Quick Fix for Most Random Build Errors

Pinned this topic :D

Indeed usually code references brake and regenerating code to fix them is all that is needed.

If this does not do the trick, 95 % of the remaining cases are fixed by: https://mcreator.net/wiki/gradle-setup-errors

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.

I dont know how to fix my issue. it says workspace setup failed, and this is the error log i think.

I have the same problem; It can't seem to download the required gradle file for the project.

I know the KB says that usually its because of slow connections, and I live in a rural area, so yes, my connection is slow. But i managed to download the file itself (In this instance Gradle-4.9-bin.zip) and I'm just wondering if it's possible to install the files yourself?

I've tried everything in the "Most common solutions" part of the KB and to no avail. (and I clicked retry 50 times xD)

Thanks! it really helped XD.

Uh, I don't understand...............
I'm havig kindaaaaa a similair problem.
Just that it shows

Nevermind, I deleted my workspace :(
But still, it would be nice if you could let me know what was the error.

Please help me, when I opened MCreator today the mod was not there, as if it had been deleted.

it happened to me too but you just have to click add workspace go to C:/users/*ur user*/mcreatorworkspaces/*ur workspace name* and than select *ur workspace name*.mcreator and click add
