Setting Java version for maven build

Question

I am trying to set the java version for a maven build when I execute it from a shell script. Fot some reason it is not picking up the intended java version. Any advise welcome.<

Answer 1

I found a solution:

If I set, this it works. Maven compiles the code.

    /usr/lib/jvm/jdk-14.0.2/bin/javac

However, this is not ideal because the path to the install is hard-coded, so on other servers with a different JAVA_HOME location, it won't work. Is it possible to reference $JAVA_HOME from within the POM file? and do something like this?

    <$JAVA_HOME>/bin/javac

e.g.

        
            org.apache.maven.plugins
            maven-compiler-plugin
            
                ${java.version}
                ${java.version}
                ${java.version}
                ${java.version}
                true
                /usr/lib/jvm/jdk-14.0.2/bin/javac
