Arch Linux User Repository

@joemaro Did you try clearing cache and resyncing before rebuild?

@Reycko I'll consider it if it solves a real problem, but right now I don't see any benefit. The script would still be complicated to avoid the problem people were having.

Thank you for creating this :) I feel as if this PKGBUILD could take advantage of the archlinux-java tool to detect a java 17 runtime instead of using a hardcoded assumption of openjdk Something like

archlinux-java status | awk '/'"$_java_ver"'/ {print $1}'

should do the trick

As previously reported, the application fails to start with Java25, even though it is actually installed.

The issue lies in the shell startup script: /usr/bin/mindustry. The program successfully finds the installed Java25, saves its path in the JAVA_HOME shell variable, but then still launches default Java:

exec /usr/bin/java -jar /usr/share/java/mindustry/mindustry.jar "$@"

To fix update the launcher script changing the last line to: exec "$JAVA_HOME/bin/java" \ -jar /usr/share/java/mindustry/mindustry.jar "$@"

Full fixed script /usr/bin/mindustry:

#!/usr/bin/env bash

_java_ver=25
_best=""

for d in /usr/lib/jvm/java-*-openjdk; do
    if [ -d "$d" ]; then
        n=$(grep -Pom1 'java-\K[0-9]+' <<< "$d")

        if (( n >= _java_ver )); then
            _best="$d"
            break
        fi
    fi
done

if [ -z "$_best" ]; then
    echo "No compatible Java version found."
    exit 1
fi

export JAVA_HOME="$_best"

exec "$JAVA_HOME/bin/java" \
    -jar /usr/share/java/mindustry/mindustry.jar "$@"

i'm having the exact issue fibonacci is

When I am starting mindustry, I get the message that java 25 is required but java 8 is installed. I tried clean building the package build. As far as I can see in pacman the build installs java-runtime. Is it possible to record the java dependency more precisely?

@Pavlov. Please let that be your last comment on this non-issue. Edit your last comment if you need to revise your alternate PKGBUILD.

There are still some things to modify, but just as is is far way better than your own, and doesn't use any eval or dynamically generated bash code and generates correct .SRCINFO information. You can still improve it, for example removing java-runtime from mindustry-icons dependencies.
