From now to then, my Maven 2 started to mess around.
I am using SPring STS 2.6.1 and have a single project based on Spring 3, Hibernate, DWR, Cometd and all that stuff.
Today I just updated from Git und all of a sudden, I got that scary mvn exclamation mark (!) next to my project.
After hitting «Project -> Maven -> Update dependencies» I just receive:

I then checked on my Mac /Users/XYZ/.m2 and all jar files are in place as expected.
I am using the current Maven release shipped with STS. I also enabled debug output but there was nothing suspicious.

There are a few other options apart from Project->Clean, some of which are more along the lines of turning it off and on again.
- Try right-clicking on the project and selecting Maven->Update Project Configuration.
- Disable then re-enable dependency management (right-click Maven->Disable Dependency Management then Maven->Enable Dependency Management
- Close the project and reopen it.
- Check that your Maven settings are configured correctly. If you are behind a proxy you’ll need to configure the proxy settings in the global or user settings.
- Check you’re using the Maven installation you expect. By default m2eclipse uses the embedder, if you have a separate installation you may want to configure m2eclipse to use the external installation so that CLI and Eclipse builds are consistent. This also ensures you’re configured to connect through any proxy as above.

I received this same issue on SpringSource Tools ver 2.8.0.RELEASE. I had to do Maven -> Update Maven Dependencies and check the option for «Force Update of Snapshot/Releases».

I encountered similar issue. The missing artifacts (jar files) exists in ~/.m2 directory and somehow eclipse is unable to find it.
For example:
Missing artifact org.jdom:jdom:jar:1.1:compile
I looked through this directory ~/.m2/repository/org/jdom/jdom/1.1 and I noticed there is this file _maven.repositories. I opened it using text editor and saw the following entry:
#NOTE: This is an internal implementation file, its format can be changed without prior notice.
#Wed Feb 13 17:12:29 SGT 2013
jdom-1.1.jar>central=
jdom-1.1.pom>central=
I simply removed the «central» word from the file:
#NOTE: This is an internal implementation file, its format can be changed without prior notice.
#Wed Feb 13 17:12:29 SGT 2013
jdom-1.1.jar>=
jdom-1.1.pom>=
and run Maven > Update Project from eclipse and it just worked

I had the same problem. Rich Seller’s solution didn’t work for my situation, I fixed it by cancel the Window -> Preferences -> Maven. Do not automatically update dependencies from remote repositories option, then right-clicking on the project and selecting Maven->Update Project.

I had similar problem. it was showing error «Missing artifact……».After digging in, I found that I have proxy settings enabled which should be configured (proxyname, user/pwd) in setting.xml inside conf folder of Maven. As a resolution go to
Eclipse….Windows->preferences->Maven->UserSettings….and update the user setting to point the setting.xml which you have inside conf folder of Maven. After that go to Project->Update All Maven Dependencies. It should work fine after the build.

I was facing the same error with Spring Boot dependencies. What solved for me was letting Maven resolve the dependencies wrapping them with dependency management:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.3.0.RELEASE</version>
</parent>
<dependencyManagement>
<dependencies>
<dependency>...</dependency>
...
</dependencies>
</dependencyManagement>

Wow, this had me tearing my hair out, banging my head against walls, tables and other things.
I had the same or a similar issue as the OP where it was either missing / not downloading the jar files or downloading them, but not including them in the Maven dependencies with the same error message.
My limited knowledge of java packaging and maven probably didn’t help.
For me the problem seems to have been caused by the Dependency Type «bundle» (but I don’t know how or why). I was using the Add Dependency dialog in Eclipse Mars on the pom.xml, which allows you to search and browse the central repository. I was searching and adding a dependency to jackson-core libraries, picking the latest version, available as a bundle. This kept failing.
So finally, I changed the dependency properties form bundle to jar (again using the dependency properties window), which finally downloaded and referenced the dependencies properly after saving the changes.

Finally, it turned out to be a missing artifact of solr that seemed to block all the rest of my build cycle.
I have no idea why mvn behaves like that, but upgrading to the latest version fixed it.

I had the similar problem. Just after adding below dependency
<dependency>
<groupId>xerces</groupId>
<artifactId>xercesImpl</artifactId>
<version>2.9.1</version>
<type>bundle</type>
</dependency>
caused the problem. I deleted that dependency even then I’m getting the same error. I don’t know what happened. I tried updating the maven dependency configuration which solved my issue.

After not much success with any of the answers available here so far.
My solution:
I downloaded the jar file manually and then installed the dependency by using Apache Maven install:install-file plugin, see more details here
A Full Example:
<dependency>
<groupId>commons-net</groupId>
<artifactId>commons-net</artifactId>
<version>3.4</version>
</dependency>
-
Download jar file from here
-
Install it by using the following command:
mvn -X install:install-file " -DgroupId=commons-net" "-DartifactId=commons-net" "-Dversion=3.4" "-Dpackaging=jar" "-Dfile={your_full_downloads_path}/commons-net-3.4.jar"
- Click on the project and select
Maven->Update Project

I had the same problem, maven was complaining about a missing artifact, even though it existed in .m2/repository/[…]. In my case the problem was that I forgot to specify the correct repository in the pom.xml from which the package was downloaded originally (download by another project).
Adding the package repository to the pom.xml solved the problem.
<repositories>
<repository>
<id>SomeName</id>
<name>SomeName</name>
<url>http://url.to.repo</url>
</repository>
</repositories>
Thanks Maximilianus for the hint to those «*.repositories» files in the package directory.

Ohh what a mess! My advise: When its comes to messy poms or project packaging, Eclipse is really bad at showing the real problem. It will tell you some dependencies are missing, when in fact for pom is malformed or some other problem are present in your pom.
Leave Eclipse alone are run a maven install. You will get to the real problem really quick!

<dependency>
<groupId>dom4j</groupId>
<artifactId>dom4j</artifactId>
<version>20040902.021138</version>

and my problem starts…so then i changed the version and took previous version and it removed all error. So i think this issue can because of the version we are adding in POM.xml file.

The following steps worked for me.
1) Cut all the contents from pom.xml file and keep it another file and save the pom.xml
2) Just delete .m2 folder(entire maven repository) and restart the eclipse(or jbdevstudio)
3) paste the previous pom.xml file content(from the cut file) and all the error are gone.

I faced this problem a couple of times. The following solution worked for me.
- copy the existing pom file as a back up, and delete the dependency that’s causing this error. delete the contents of the folder which this artifact is referring to.
- add the deleted dependency in the pom again and add the jar files in that folder.
- do a Maven->update Project. The errors will go away.
As a side note, sometimes when you’re copying files from some other computer there may be encryption.

I had a similar solution like @maximilianus. The difference was that my .repositories files were called _remote.repositores and I had to delete them to make it work.
For eg in my case I deleted
- C:UsersUSERNAME.m2repositoryjtajta1.0.1_remote.repositories and
- C:UsersUSERNAME.m2repositoryjndijndi1.2.1_remote.repositories
After doing so my errors disappeared.

I was getting a similar problem with SBT and slf4j. Nothing had changed, but on one machine it suddenly wouldn’t build.
I tried:
- sbt clean
- deleting
target/ - deleting project working directory and doing a fresh checkout/build
- deleting the
~/.sbt/<scala-version>/folder - deleting the offending slf4j folder from the
~/.ivy2cache - placing the missing slf4j jars in the expected ivy2 folder
None of the above worked.
So, I had to bite the bullet and delete my entire ~/.ivy2/ cache folder and wait for 2GB of dependencies to be downloaded again. I’m not familiar with what sort of cache manifests get written in there, but this must have been a corruption of one of them.

If the other solutions didn’t work and you know the correct jars are in your repository then:
The problem is that eclipse caches the errors for some reason.
I solved this problem by deleting the errors in the Problems tab and then I refreshed the project explorer and all the exclamation points and errors never returned.

I have seen a bug that manifested as «Error installing artifact: File ../null/… does not exist» (that is, the file was not found because there was «null» in the path). The reason was that one environment variable was not visible to maven. It was:
JV_SRCROOT=$DIRECTORY
instead of
export JV_SRCROOT=$DIRECTORY
(in the latter case the variable is visible to child processes)

If nothing else works which was the case for me, in the problems view, right click and copy the errors and paste it in a text editor. And scroll down to see if there are other errors besides just the missing artifact.
Eclipse problems view only shows about 100 errors and the errors that are not visible might be the ones that’s causing all the other missing artifact errors.
Once I saw all the errors, I was able to figure out what the issue was and fixed it.

By deleting the _remote_repositories file in the same directory as the «missing jar file» and doing maven update I got it to work.

In this example, we will be discussing about how to resolve “Missing Artifact” error while using Maven. Before we start with this article, it is expected that we have a basic understanding of how software development works with Java. It would also be good if we have an exposure to software build and deployment process to understand the usage and the working of the Apache Maven better. To get familiar with the installation, the usage and the basics of Maven please refer to the article Maven Hello World.
In this example, we will see how to resolve “Missing artifact error” while working with Maven.
1. Introduction
In general software terms, an artifact is something produced by the software development process, whether it is software related documentation or an executable file.
In Maven terminology, an artifact is a file, usually a JAR, that gets deployed to a Maven repository. It is a resource generated by a maven project. Each maven project can have exactly one artifact like a jar, war, ear, etc. Each artifact has a group ID (usually a reversed domain name, like com.jcg.maven), an artifact ID (just a name), and a version string. The three together uniquely identify the artifact. You can refer to the pom.xml below.
pom.xml
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.jcg.maven</groupId> <artifactId>MavenHelloWorldProject</artifactId> <packaging>jar</packaging> <version>1.0-SNAPSHOT</version> <name>MavenHelloWorldProject</name> <url>http://maven.apache.org</url> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> </dependencies> </project>
2. Missing Artifact error
Maven artifacts are not limited to java resources. We can generate whatever resource we need like, documentation, project-site, zip-archives, native-libraries, etc.
Each maven project has a unique identifier consisting of [groupId, artifactId, version]. When a maven project requires resources of another project a dependency is configured in it’s pom.xml using the [groupId, artifactId, version] identifier. Maven then automatically resolves the dependencies when a build is triggered. The artifacts of the required projects are then loaded either from the local repository, which is a simple directory in user’s home, or from other (remote) repositories specified in the projects pom.xml.
Maven throws “Missing artifact error” when a dependency is not recognized or a dependency artifact cannot be found either in the local repository or the remote repository depending on how we have configured our project to get the dependencies (check the <url> tag in pom.xml which helps to determine where maven will refer the dependencies). It may also means that Maven is not able to download the artifacts specified in the pom.xml from the repository.
3. Resolving Missing Artifact error
Whenever we get a missing artifact error while building our Maven project, the only thing we should first try out is to check for dependencies in the pom.xml.
Things that can be checked in pom.xml:
- Check if the correct repository is specified in the
pom.xmlfrom which the package was downloaded originally. It might happen that the url inpom.xmlis not correct and you have the required jar file in the .m2 repository. - Check for the artifact version, if the version specified in the
pom.xmlis there in the repository from where it should be downloaded. - Check if the jar is missing or not. If yes, place it manually in the .m2 repository. Sometimes the jar mentioned in the
pom.xmlis not downloaded and it gives error. - You can also try deleting the entire .m2 repository folder and run the maven build. The jars get downloaded from scratch. It might resolve the problem as well.
- In eclipse, you can always try to clean the project by selecting the Project->Clean option. There are a few other options apart from Project->Clean, some of which are more along the lines of turning it off and on again.
- Try right-clicking on the project and select Maven->Update Project.
- Disable then re-enable dependency management (right-click Maven->Disable Maven Nature then to again convert the project to a Maven project, Right Click on the project and select Configure ->Convert To Maven Project. Please refer to the screen shots below.
- Close the project and reopen it.
Fig 1: Disable Maven Nature
Fig 2: Convert To Maven Project
6. Check that your Maven settings are configured correctly. If you are behind a proxy you’ll need to configure the proxy settings in the global or user settings.
7. You can also try right-clicking on the project and select Maven -> Update Project and check the option for “Force Update of Snapshot/Releases”. It will clean build the project checking for dependencies. Refer to the screenshot below.
Fig 3: Force Update of Snapshots
4. Conclusion
That was an example of the “Missing Artifact error” while building a Maven project. We saw some things that can be checked in order to resolve this error.
In maven, missing artifact error in pom.xml is due to dependency download problem. The error in pom.xml “missing artifact maven” occurs when the artifact is missing in local repository and remote repository. In eclipse, missing artifact maven error shows in the programs window.
Maven is a software tool for building artifacts. The maven exception “Missing artifact” is thrown when a new dependency is added in the pom.xml file. A maven dependency is identified with group Id, artifact Id and version. If there is a problem related to these parameters, the exception “Missing artifact” will be thrown from maven pom.xml.
The code below displays an error message “Missing artifact Maven” due to dependency problem. In eclipse, along with this exception, additional errors will be shown in the programs window.
Missing artifact org.apache.commons:commons-lang3:jar:3.9.1
The container 'Maven Dependencies' references non existing library '../../.m2/repository/org/apache/commons/commons-lang3/3.9.1/commons-lang3-3.9.1.jar'
The project cannot be built until build path errors are resolvedRoot Cause
The exception “missing artifact maven” can occur if a new dependency is added in the pom.xml file. Maven will check the dependence of the local repository. If this is not available, try downloading it from the source url. If the dependency is not present in either local repository or remote repository, this exception will be thrown.
There might be a different reason not to find the dependent jar files. Maven distinguishes dependency based on three factors, group id, artifact id and version.
Solution 1
Check the group id and artifact id in the dependency configuration in pom.xml. If this is a spelling error, correct it and refresh. This exception will be resolved. Make sure that the group id and artifact id are correct in the pom.xml file. The artifact like jar file is located using these parameters.
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-lang3</artifactId>
<version>3.9.1</version>
</dependency>Solution 2
For this exception, the version is an important factor. The jars are placed in a path that is based on group id and artifact id. There are several jars available for a dependency based on their versions. For example, the jar file is going to have different versions. The jar is added to the project on the basis of the version specified in pom.xml.
First, make sure that the version number is correct. Check whether the file is available in the local repository or not. Check the version in the downloadable link on the internet.
Solution 3
Check the jar file in your local repository. The version folder is sometimes created in the local repository, but the jar file is missing. This will happen if the internet is disconnected while downloading or if something happens while downloading the jar file. In this case, there will be a folder in the local repository. But the jar file is not going to be available.
Download the jar file from the internet and place the jar file in your local repository folder.
Solution 4
This solution is not recommended at all times. If you are not concerned about your.m2 local repository, delete the local repository and refresh the maven project. Maven is going to try to download all the jars from scratch. If there is a repository related issue, this step will resolve the exception “missing artifact maven”.
Note that this will also affect other maven projects as you delete a complete.m2 local repository. It is recommended that you take backup of the entire.m2 local repository.
Solution 5
If you use eclipse as your IDE, recompile the entire project. Click “Project->clean” in the menu. This will clean up all of the target and bin folders. If there is any issue in the folder structure of the maven project, this step will resolve the issue. If any file is locked in the target or bin folders, fix it first. From the menu, click “Project->clean.”
Run the maven after cleaning the project build directory. This step is going to solve the exception.
Solution 6
In the maven project, right-click the name of the project, click “Maven->Update Project.” If any problems occur while downloading or linking the jar to the maven project, they will be resolved in this step. Maven is trying to check all the dependency jar links with the local repository and remote repository. In this step, if any issues related to linking jars will be resolved. The maven error missing artifact will also resolved.
Solution 7
If none of the above steps is working, then try these steps to resolve missing artifact maven error in pom.xml
- try to close the project and open up the project
- try to close the eclipse and begin the eclipse again
- try to shut down your system and restart your system.

A friend has passed me a Maven project that I’m trying to run locally in my computer. All that I have done in Eclipse, I selected:
File -> Import -> Existing Maven Projects
After that, the project showed me 4 errors in my pom.xml (Missing artifact..):
I tried removing the content of .m2 folder and then in Eclipse I clicked on my project and chose «Run as» -> «Maven clean» and then «Run as» -> «Maven install». But I still have the same errors. I’m new with Spring so I dont know what else to do.
EDIT:
When I try to do: run as/ maven install, this is what my console says:
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
