Gradle setup and build errors

It can happen that you get gradle errors during the setup of MCreator or even later when suddenly builds stop working. Most of these errors are related to file permissions, firewalls and other OS elements that block MCreator from operating properly. To find the solution for your case, check the error log in the Console tab and look for error messages similar to the titles on this page and if you find one of these, go to the section under this title to look for the solution.

The most common solution

In most cases all Gradle errors are caused by one of these:

• Firewall or antivirus blocking MCreator
• Slow internet connection
• Your ISP blocking certain websites
• Too slow VPN or VPN with blocked domains that MCreator needs to access
• Any other software blocking access to download repository

The most common errors from Gradle are caused by firewalls or antivirus software. If you have any issues, we recommend you to temporarily turn off this software and try again. If this works, add MCreator as an exception to your firewall or antivirus or reconfigure the software properly to not block programs such as MCreator.

It can also happen that the servers from which Gradle downloads files (Minecraft servers, Minecraft Forge repo, Maven repository) are down and you might just need to try again later in such cases.

In some cases of unstable or slow connections, running the setup multiple times and when it fails with errors related to the internet connection (timeout errors, failed to connect, failed to GET, HEAD, . ) clicking re-run the setup multiple times resolves the issue as eventually, all files get properly downloaded.

The second most common solution

In some cases, Gradle caches that make sure the build process does not take too long can get corrupted. In such a case, go to:

In this folder, there is a folder called caches. Delete this folder and open MCreator again. Next build will take a bit longer as caches need to be rebuilt. If you can not delete all files in this folder (which is necessary), reboot the computer first to remove any potential file locks.

If this is not enough to make things work, delete the entire gradle folder, not just caches, and try again.

If even this fails, try to delete the entire /.mcreator/gradle folder, create a new workspace with the same generator version as the version of the workspace failing, after the setup of this new workspace is done, open your current workspace, and click Build & run -> Build workspace, then Build & run -> Reload gradle project and then Build & run -> Regenerate code and build.

Common error types

Could not get unknown property ‘runClient’ for root project ‘forge’

The first thing to check is to do The second most common solution described above.

Another solution is to make sure MCreator can write to the folder where the workspace is stored.

If none of this helps, do The second most common solution and reinstall MCreator before opening it again.

ValidatorException: PKIX path building failed

Example of the error log in the Console tab:

The most common cause for this issue is Antivirus with any advanced SSL or HTTPS security turned on. Such Antiviruses can alter certificates and cause Gradle to no properly recognize them. This can be caused by a firewall too.

Could not resolve all dependencies for configuration ‘:classpath’.

Example of the error log in the Console tab:

This issue is resolved by The most common solution described above.

java.util.zip.ZipException: error in opening zip file

Example of the error log in the Console tab:

This issue is resolved by The second most common solution described above (but delete the entire gradle folder, not just the folder caches in it). You might need to restart your computer before opening MCreator again too.

Timeout of 120000 reached waiting for exclusive access to file

Example of the error log in the Console tab:

Close MCreator and reboot your computer. Then read and do The second most common solution described above (but delete the entire gradle folder, not just the folder caches in it).

Could not connect to the Gradle daemon

Example of the error log in the Console tab:

In most cases, this error can be fixed by rebooting MCreator. If this does not help, do The second most common solution described above.

Failed to load native library ‘native-platform.dll’ for Windows 10 amd64

Example of the error log in the Console tab:

In this folder, there is a folder called native. Delete this folder and open MCreator again. If this does not help, try reinstalling Minecraft on your computer and check your graphics card drivers (update them if there are updates).

org.lwjgl.LWJGLException: Pixel format not accelerated

Example of the error log in the Console tab:

This error usually means that you have an unsupported graphics card for Minecraft our outdated graphics card drivers. These pages could help:

Sometimes reinstallation of Minecraft can help too.

Expected BEGIN_OBJECT but was STRING at line 1 column 1

Example of the error log in the Console tab:

This issue is resolved by The second most common solution described above (but delete the entire gradle folder, not just the folder caches in it). You might need to restart your computer before opening MCreator again too.

Gradle task compileJava FAILED with errors of type «Override is not a repeatable annotation type»

In some cases, links to the libraries from the Gradle build system can get lost and MCreator builds will stop working. Especially some mod elements such as GUIs and dimensions are prone to this happening. When this happens, the following solution usually fixes this error:

Go to the Build & run menu and click the following two options in the given order

1. Reload Gradle project
2. Regenerate code and build

Wait for the workspace code to be regenerated and the error should be gone.

Gradle task compileJava FAILED with 100 errors of type «cannot find symbol»

This issue is resolved by The second most common solution described at the top of this page. After applying the solution, run the build again.

Error occurred during initialization of VM: Picked up _JAVA_OPTIONS

This error indicates there is an override for JAVA_OPTIONS defined somewhere. There are multiple possible places:

1. Check your computer environment variables (system and user) and if there is a parameter _JAVA_OPTIONS or JAVA_OPTIONS present, remove it from the list
2. It was reported that Razer Synapse software can override this parameter and cause compatibility problems. In this case, consider disabling or uninstalling this software

If these two do not help, make sure you are using a 64-bit version of MCreator if your computer is 64-bit, as this may cause such a problem too.

[Разное] Как исправить некоторые ошибки в MCreator?

И так начнём с того, что все ошибки указанные ниже, были обнаружены на версии 1.4.5 для версии Minecraft’a 1.7.2! Кстати всё что выделено коричнево-оранжевым цветом будет внизу описано более подробно!
Приступим:
Ошибки во время установки , скорее всего связаны с в Вашей криворукостью!
Решение:
Попробуйте переустановить minecraft! Он обязательно должен лежать в папке .minecraft!
Проверти подходит ли версия программы к версии minecraft’a!
Попробуйте установить forge или его переустановить!
Поудаляйте моды!
Ошибки во время создания или загрузки текстур блоковвещей!
Решение:
Народный способ: просто напросто пересоздать текстуру! Возможно текстура которая сделана не с помощью MCreator’a, в формате Jpg — решить это можно легко! Откройте вашу текстуру в любом ГрафРедакторе и сохраните в формате PNG !
Слишком большой размер — либо много весит, либо слишком большая. Первое решается так — открываете в ГР текстуру и сохраняете в худшем качестве (photoshop)!
Ну с большим размером (пикселы) думаю всё понятно! Советую делать текстуры для первого раза в размере 16х16 пикс.
Вылет при создании мода.
Пока нет решения.
Извиняюсь, но тут я бессилен!
Ошибки во время рекомпляции мода
Решение
Возможно в вашем моде присутствуют не поддерживаемые символы !
Или в вашем моде не стыковка, например во время создания event’a вы сделали помарку! Обращайте на это больше внимания!
Фиолетово- чёрные текстуры после создания мода !
Решение
Формат jpg (рассказывалось ранее)!
Возможно у вас текстуры не сохранились в архиве, у меня была эта ошибка и решил я её как ни странно быстро! После того как вы загрузили текстуру, её копия должна лежать в папке, а как её открыть написано ниже! После того как мы её открыли видим те текстуры (в папках Block, Item, и ещё какая ) копируем все эти три папки в архив с нашим модом (там должен быть такой же путь как и у папки с нашими текстурами)!

Тот самый низ что был вверху!
ГрафРедактор или Графический редактор — это paint, photoshop и.т.д!
ГР — сокращение Графического редактора!
Рекомпляция — это создание вашего мод, ход данного действия можно отследить сдесь:

После синих «Букв» идут красные, а потом зелёные, то значит всё чики-пуки
Поддерживаемые символы — это все знаки препинания и цифры, а также только английский язык! А как перевести ваш мод на Русский язык, я расскажу в следующем гайде!
Ну вот и всё ребяты! Вот вам ссылка что-бы скачать MCREATOR!
P.S Указывайте что я пропустил и оцените мой труд. Писал статью где то минут 20!

GeckoLib + MCreator | Ошибка при установке.

Столкнулся с проблемой загрузки GeckoLib в программу MCreator .

При компиляции или после перегенерации кода выскакивает ошибка:

По инструкции и гайдам требуется скачать плагин — Feder’s Geckolib 2.0.0 Plugin | MCreator и поместить его в папку plagins
после зайти во вкладку » Рабочее пространство/Настройки рабочего пространства. /Внешние API » и поставить галочку на против пункта GeckoLib API .

После чего по «сюжету» мы перегенерируем код.

Но тут же в консоли выскакивает ошибка

Все эти ссылки не работают.
На форумах пусто.
В интернете ничего нет.
Дальше forge_grable путь не сходится.

В чем может быть проблема? Есть ли те, кого всё работает? Какую версию Mc вы используете и может ли скинуть архивом папку bernie с всем содержимым?
Буду очень признателен.

Gradle task compileJava FAILED with errors of type «Override is not a repeatable annotation type»

In some cases, links to the libraries from the Gradle build system can get lost and MCreator builds will stop working. Especially some mod elements such as GUIs and dimensions are prone to this happening. When this happens, the following solution usually fixes this error:

Go to the Build & run menu and click the following two options in the given order

1. Reload Gradle project
2. Regenerate code and build

Wait for the workspace code to be regenerated and the error should be gone.

Gradle task compileJava FAILED with 100 errors of type «cannot find symbol»

This issue is resolved by The second most common solution described at the top of this page. After applying the solution, run the build again.

Error occurred during initialization of VM: Picked up _JAVA_OPTIONS

This error indicates there is an override for JAVA_OPTIONS defined somewhere. There are multiple possible places:

1. Check your computer environment variables (system and user) and if there is a parameter _JAVA_OPTIONS or JAVA_OPTIONS present, remove it from the list
2. It was reported that Razer Synapse software can override this parameter and cause compatibility problems. In this case, consider disabling or uninstalling this software

If these two do not help, make sure you are using a 64-bit version of MCreator if your computer is 64-bit, as this may cause such a problem too.

This may not be what you want to hear, but I would recommend not using mcreator, as it is a awful program with tons of bugs, among many other things (such as being a much less powerful tool that plain forge).

On top of that, you probably won’t get help as people who know how to fix these errors do not use mcreator (also many errors might be due to pylo)

From the error log, it seems that the error is probably not your fault, so you should report this to pylo.

I can’t tell you how to fix it, but if you were to show me the code (if you can do that) I probably could.

It appears that it is unable to find the class objects for your various coins «error: cannot find symbol mcreator_money … symbol: class mcreator_money», etc.

I don’t know what your reason for using mcreator is (whether it be lack of java knowledge, lack of confidence in java skills, uncertainty that despite knowledge of java minecraft modding might be really confusing), but regardless, I would strongly recommend downloading the forge mdk (available here), and following tutorials to get started, and referencing them or minecraft’s source code, or asking for help on the forums if you get stuck.
