Arch Linux User Repository

To build, add following to end of PKGBUILD:

# update license
license=('GPL-3.0-only')

# update makedepends
makedepends=(${makedepends[@]/java-environment*})
makedepends+=('java-environment=17')

# update depends
depends=(${depends[@]/java-runtime*})
eval _orig_"$(declare -f _package_common)"
_package_common() {
  depends+=('java-runtime')
  _orig__package_common
}

# update pkgver
pkgver=$(sed 's@_@.@g' <<< "$pkgver")
_tag=$(sed 's@^.*\.@@' <<< "$pkgver")

# add arc to source
_pkgsrc_arc="Arc-${_tag:?}"
_pkgext="tar.gz"
source+=("$_pkgsrc_arc.$_pkgext"::"https://github.com/Anuken/Arc/archive/refs/tags/v${_tag:?}.$_pkgext")
sha256sums+=('SKIP')

# prepare arc
prepare() {
  cp -rl "$_pkgsrc_arc" Arc
  cd "${_repo_name}-${_build}"
  sed -E -e '/archash/s&archash=.*$&archash=8d5651a6adebd8c04be146d9a4a95f237ecf57b2&' -i gradle.properties
}

Can also set archash=152e49944a1de4653c6aa8c822b03915fcdf25ba. Doesn't seem to make any difference (but does need to be changed, and cannot be a bogus string).

Uh, I suppose Java versions that are too new are not supported by the Gradle version Mindustry is using, try compiling with an older JDK

Installing gradle doesn't help.

https://wiki.archlinux.org/title/Java#Launching_an_application_with_the_non-default_java_version You can restrict java version in dependencies and use environment variables to select the java version which package needs.

Why don't you use the bundled archlinux gradle?

Not sure how broken the java landscape is, but shouldn't deps take care of version conflicts like this?

To build in clean chroot when cannot run archlinux-java:

• set java-environment=17 in makedepends
• remove java-runtime from depends
• put java-runtime in depends+=(...) inside package() function.

If you'd rather compile on your own, follow these instructions. First, make sure you have JDK 16-17 installed. Other JDK versions will not work. Open a terminal in the Mindustry directory and run the following commands:

sudo archlinux-java set java-17-openjdk

it may not be the right place, but it took me a lot of time to figure out i needed to do this: hopefully it we be usefull for some lurker

sudo archlinux-java set java-19-openjdk

It also builds with 'java-environment=17' or this patch
