I would recommend the following changes since jdk17 is the latest supported lts and a chroot build (or any other build) can have issues if another version of java is on the system or is set to something else. This forces the use of jdk17 during compilation unconditionally. From what I've seen the use of JAVA_HOME is only frowned upon in runtime scripts:

Since this fails to build on java 20, could you change the make dependency to something like 'java-environment<=17'? That way, it should build correctly in a clean chroot without manual intervention.

This seems to be a problem with the Java version. I solved it by switching to version 17.

pacman -S jre17-openjdk jdk17-openjdk
sudo archlinux-java set java-17-openjdk

After compile and install I switched back to Java 20.

sudo archlinux-java set java-20-openjdk

I've just switched to binaries and it's all fine

@bkb You need to use archlinux-java to set your default java version to one for which you have a JDK installed.

@trainzkid Not good advice. This package depends on the shared library quazip-qt6 provides. All you need to do is rebuild it with the updated package installed (1.4 in this case).
