>What I'm trying to do is compile only the classes that are 
>needed for specific targets not all the targets in the source 
>tree. And do so without having to specify the files every 
>time. Here are how the targets are defined:
>
>  <target name = "compile-examples"
>      depends  = "init">
>    <compile sourceref = "${toString:java.source.examples}" />
>  </target>
>
>  <target name = "compile-project"
>      depends  = "init">
>    <compile sourceref = "${toString:java.source.project}" />
>  </target>
>
>  <target name = "compile-tests"
>      depends  = "init">
>    <compile sourceref = "${toString:java.source.tests}" />
>  </target>

>As you can see each target specifies the java files to be 
>compiled as a simi-colon separated list of absolute file 
>names. The only problem with this is that javac does not 
>support filelist. It also does not support fileset, path or 
>pathset. I've tried using <include name = "@{sourceref}" /> 
>but it treats the list as a single file name. Another thing I 
>tried is sending the reference directly (not using toString) 
>and using <include ref = "@{sourceref}" /> but include does 
>not have a ref attribute.
>
>I've done a search of this list and noticed another person 
>with a similar problem. But while it was discussed no solution 
>was presented.
>
>SO THE QUESTION IS: How do you get the javac task to use a 
>reference to a fileset that was defined in another part of the 
>build file? I'm not interested in solutions that cause me to 
>have multiple javac tasks. Completely re-writting the macro is 
>acceptable. Changes to the targets are also acceptable 
>provided redundant code between targets is kept to a minimum.
>
>p.s. Another problem is that fileset wants a comma separated 
>list. I've only done a brief search for a way to convert 
>semi-colons to commas and haven't found a way to do that.

>p.p.s. Sorry for the yelling but some people are too quick to 
>post responses that don't address the subject.
