I struggled to launch this. The package depends on java-runtime=21, but jdk21-openjdk isn't enough to get it working. I had to install jre21-jetbrains instead. Should that be an explicit dependency instead?

E: I had a lot of trouble getting this to work. I had to install jre21-jetbrains to get it to even launch, then hardcode the java version into the launch script. However it was freezing when creating a new project. I tried installing the newest version of mcreator. Here is a patch to update.

I hardcoded jre-jetbrains, although jdk25-jetbrains-bin might work too. FWIW neither jre-openjdk 26.0.1.u8-1 nor jdk25-openjdk work.

I then edited the launch script /opt/mcreator/mcreator.sh to hardcode the new correct jetbrains java

Thanks @inetol, just updated the package.

@impulse I added you as a co-maintainer.

Can someone add me as co-maintainer? I use this program occasionally.

Release 2025.2.28610-1 will be the last one I make. If anyone wants to become the maintainer of mcreator, contact me via the PKGBUILD maintainer email.

Hi @beanie, I didn't have my testing environment at hand for a few days so I couldn't test if the package was working properly, I'll update PKGBUILD rn. Thank you.

updated the PKGBUILD to recent version but can't push to aur... if Inetol or whoever wants to update it's all yours

If anyone else wishes to maintain and upgrade this package, please do so. I am unable to do so at this time.

I could totally 100% maintain this package, if I could find a new tar download URL that was actually supported by curl.
