Issue comments

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 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 -> Reload gradle project and then Build & run -> Regenerate code and build.

Ok. It persisted after deleting and recreating it, but when making a differently named workspace, it worked(the new workspace was called gun and the other new workspace was called guncraft, and the old one was called warcraft
