Possible values for Ant Javac attributes "source", "target", "compiler" across various JDK versions?

Question

For the Ant javac task below, is there a resource that lists the values of source, target, and compiler for various JDK versions?

<target name="_compile" depends="">
    <echo message='compile excludes ${javac.excludes} includes ${javac.includes}'/>
    <javac
        srcdir="${javac.srcdir}" 
        destdir="${javac.destdir}" 
        classpathref="project.class.path"
        classpath="${javac.classpath}"
        includes="${javac.includes}"
        excludes="${javac.excludes}" 
        compiler="${javac.compiler}" 
        source="${javac.source}"
        target="${javac.target}"
        nowarn="${javac.nowarn}"
        optimize="${javac.optimize}"
        deprecation="${javac.deprecation}"
        verbose="${javac.verbose}"
        debug="${javac.debug}" 
        debuglevel="${javac.debuglevel}" 
        fork="${java.fork}"
        listfiles="${javac.listfiles}"
        includeantruntime="false"
        />
</target>

The values for the Ant build file are managed in project-specific property files. For example, a legacy project that I was working on had javac.source=1.8, javac.target=1.8, javac.compiler=javac1.8. My priority is to find out these values for the LTS versions of JDK (i.e 11 and 17), but it would be great if I can see all the various values.
