The first thing to check is to do The second most common solution described above.Īnother solution is to make sure MCreator can write to the folder where the workspace is stored.

Common error types Could not get unknown property 'runClient' for root project 'forge' 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. If this is not enough to make things work, delete the entire gradle folder, not just caches, and try again.

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

Delete this folder and open MCreator again. In this folder, there is a folder called caches. In some cases, Gradle caches that make sure the build process does not take too long can get corrupted. ) clicking re-run the setup multiple times resolves the issue as eventually, all files get properly downloaded. 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. 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. 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. If you have any issues, we recommend you to temporarily turn off this software and try again. The most common errors from Gradle are caused by firewalls or antivirus software. Any other software blocking access to download repository.Too slow VPN or VPN with blocked domains that MCreator needs to access.Firewall or antivirus blocking MCreator.In most cases all Gradle errors are caused by one of these:

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. Most of these errors are related to file permissions, firewalls and other OS elements that block MCreator from operating properly. Run with -stacktrace option to get the stack trace. Run with -info or -debug option to get more log output. Run with -scan to get full insights.It can happen that you get gradle errors during the setup of MCreator or even later when suddenly builds stop working. > Could not GET ' '.

So im confused to why there is a problem, any help is greatly appreciated.Įxecuting gradle task: setupDecompWorkspace -refresh-dependenciesīuild info: MCreator 209, 1.12.2, 64-bit, 16328 MB, Windows 10, JVM 1.8.0_232, JAVA_HOME: C:\Program Files\Pylo\MCreator\jdkĪ problem occurred configuring root project 'testing123'. I have a 圆4 computer with 16gb of ram, a gtx 1060 3gb and 30mb download/18mb upload from a speed test. I can install mcreator and run it but when it tries to setup and download files from it says there is no internet connection, it been just over 3 days now and im starting to think that if this was a forge outage this would be fixed by now, and yes i have tried deleting my antivirus software and turning windows defender off.
