First of all I want to say that in my opinion your code looks fine. I am a
little bit astonished by the part:
<javac srcdir="${src}" destdir="${bin}" includeAntRuntime="no"
classpathref="lib.path" debug="${compile.debug}">
<compilerarg value="-classpath"/>
<compilerarg value="/System/Library/Java/"/>
</javac>
Maybe, I am not quite sure, so maybe there is a problem when using
classpathref and <compilerarg value="-classpath"/>. I don't know whether
some kind of confrontation could arise. Let me suggest you something. You
have a
<path id="lib.path">
<fileset refid="lib.jars"/>
</path>
defined. Why don't you just add your folder to this path and then call
classpathref="lib.path" in your javac task. Something like this should work:
<path id="lib.path">
<fileset refid="lib.jars"/>
<fileset dir="/System/Library/Java">
<include name="**/*.*"/>
</fileset>
</path>
Also tell me does your code now compile and breaks down during execution or
you can't compile it at all?
