Ant - how do I pass parameters to forked javac?

[Steve Dalton]

Hi All

I am currently running ant under java 1.3 (long story - but this is so I can run the Borland BES 5.1 java2iiop command - won't run under anything else).

I have a requirement to now use a third party java 1.5 built jar (Adgen 7.5 runtime). I can't do this in the 1.3, so my plan was to make the javac command run under java 1.5, but targeting the resulting classes back to 1.3 (using target=1.3).

I'm using the following task

  <target name="compile" depends="init" description="compile the source ">
    <!-- Compile the java code from ${src} into ${build} -->
  <mkdir dir="${build}/${prefix}"/>
        <javac srcdir="${src}/${prefix}/src" destdir="${build}/${prefix}"
    fork="yes"
    compiler="javac1.5"
        executable="C:/apps/Java/jdk1.5.0_08/bin/javac"
        target="1.3" source="1.3">
<classpath refid="build.classpath"/>
    </javac>
  </target>

However when the compiler is external the parameters to javac are ignored (I get a warning).

Is there any way to do this???

Without the options being passed, the resultant jar is a 1.5 jar - which just passes the problem up to the next layer in the system. At some point I need to bring the bytecode down to v1.3, and the lower the better as this is the only part of the system where we have a dependency on java 1.5.

Any other suggestions also welcome!

Regards
Steve

Just answering my own question here....

Just upgraded to Ant 1.6.5 (was using 1.6.2 before) and the fork now passes the parameters.

I now have another problem in that the java2iiop doesn't like my 1.3 targetted classes (insists they a v49 - which is java 1.5, but I have looked at them with a hex editor and they are definitely 47) - but this is another problem now not Ant.
