Arch Linux User Repository

Please note that this package builds Mindustry from the latest source code. If you wish to build a specific release, make sure to add something like "#tag=v108" to the git repository in the sources array, or use one of the Mindustry packages by dmitmel.

Ok, I managed to fix it. It was indeed a mistake I made myself.

I changed to java-14-opendjk via archlinux-java, even though I only installed the runtime environments and not the jdk itself.

Since there were still other Java versions installed (8 and 10), I guess gradle tried to use those old jdks as a fallback?

Anyway, the issue has been fixed and everything works perfectly fine.

I'm sorry for any inconveniences. I didn't expect this whole java version juggling to be this confusing :D

Thanks for your time and this PKGBUILD!

@Nukesor: Package builds for me. The only difference I can see is the "_JAVA_OPTIONS" line. I've asked in the game's Discord to see if anyone knows more. So far setting -Djdk.attach.allowSelfAttach=true has been suggested (which you might be able to set in _JAVA_OPTIONS or the newer JDK_JAVA_OPTIONS / JAVA_TOOL_OPTIONS?) - also something that came up when searching for your error.

The current git build fails with JDK14:

JDK 14 is now recommended in the README

Updated the package as by vasya's comments. Doesn't use absolute paths anymore so it respects $PATH. I decided to keep the java-runtime=8 dependency for now, as that appears to be recommended to build (and play?) as per the project's readme. If you wish, you can always change the requirement to >= this before you build the package.

I also changed all the file and folder names to remove the -git suffix as per recommendations in the #archlinux IRC channel, and made the package provide and conflict with other mindustry packages. I initially intended this package to be playable alongside a stable version of the game, but as both versions would use the same configuration folder, it could cause issues.

I noticed myself that I could not build the game from the latest source code. If you run into a similar issue, try to build from the most recent release tag instead (see pinned comment and https://github.com/Anuken/Mindustry/releases), and perhaps report it to the developers.

Also, same as with the mindustry AUR package, can you please change the java-runtime requirements from 8 to >=8 ?

Can we change .desktop file to call Exec=mindustry-git instead of /usr/bin/mindustry-git, and the main executable to call java instead of /usr/bin/java ? This is the preferred way I think. The user might want to override the binaries in e.g. /usr/local/bin, and it makes sense to allow it. Also, this is how all other .desktop behave as far as I see. Thanks for the package!

I updated the package to require JRE and JDK version 8 exactly, hopefully fixing the "Could not find tools.jar." issue. Unsure if a newer JRE would also work for just running the game, but I'll keep it simple, as it is required for building according to the README.
