Hi,
When a port defines JAVA_VERSION but during the build multiple jdk versions are installed, maven does not use the defined version if JAVA_HOME is not set in the environment.
I found this while pinning ports to openjdk8 and defining JAVA_DEFAULT=21 [1]. Dependencies install openjdk21 as run_dep which is picked up by maven, although JAVA_VERSION of the current build is 8.
The patch in the attachment makes sure JAVA_HOME is set. This fixes the builds.
I used this to find the relevant ports.
find . -name Makefile | xargs grep -l bin/mvn | xargs grep -L JAVA_HOME
NB: for ant we set a similar MAKE_ENV in Mk/Uses/java.mk. It might be a nice follow up task to add maven support to java.mk. I first want to get JAVA_DEFAULT=21 in the ports tree.
Is it possible to get some java@ approval for such a change without going through the hassle of creating separate PRs for every port?
Regards,
Ronald.

many: pass JAVA_HOME to maven
When a port defines JAVA_VERSION but during the build multiple
jdk versions are installed, maven does not use the defined version
if JAVA_HOME is not set in the environment.
