Что делать если mcreator выдает ошибку

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:

<your user home folder>/.mcreator/gradle

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 <your user home folder>/.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.
