[ERROR] Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.5.0:exec (generate schema types) on project sparqlify-core: Command execution failed.: Cannot run program "xjc" (in directory "/home/konrad/opt/sparqlify/sparqlify-core"): error=2, No such file or directory -> [Help 1]
KonradHoeffner commented 3 years ago

Ich denke das Kernproblem ist java.io.IOException: Cannot run program "xjc" (in directory "/home/konrad/opt/sparqlify/sparqlify-core"): error=2, No such file or directory.

Ich schätze mal, das bezieht sich auf https://docs.oracle.com/javase/8/docs/technotes/tools/unix/xjc.html

Compiles an XML schema file into fully annotated Java classes.

Das gibt es nicht als Arch Linux-Paket aus den Standardquellen, pacman -Ss xjc liefert keinen Treffer.

Interessanterweise wird es aber unter https://man.archlinux.org/man/xjc-openjdk8.1.en gelistet unter dem Package extra/jdk8-openjdk. Außerdem gibt es auf meinem System einen Softlink May 16 2020 /usr/bin/xjc -> /usr/lib/jvm/default/bin/xjc der aber ins leere geht.

Mein Verdacht ist, dass xjc früher mal Bestandteil von Java war und in den modernen Versionen nicht mehr enthalten ist. Ich verwende openjdk 15.0.2 2021-01-19.
