ant, jar with selected directories

Hello,

I'm tyring to use Ant to create a jar file with selected directories in
a potentially large tree.
For example:

<property name="top.dir" value="/javasrc"/>
<property name="util.dir" value="/javasrc/my/stuff/util"/>
<property name="Proj1.dir" value="/javasrc/other/stuff/Proj1"/>
<property name="jar.file" value="Proj1.jar"/>

I can do this:

<jar basedir="${top.dir}" destfile="${top.dir}/${jar.file}"
includes="**/*.class">

But of course I get all classfiles under /javasrc. I've been tinkering
with includes= and <fileset> to try and pick and choose the directories
to include, without success. Also, I often get just the class file name
referenced in the manifest, but what I need is

/javasrc/my/stuff/util/a.class

So far the only thing that's worked is includesfile, but then I have to
maintain the file. This seems like a pretty natural thing to do... Any
suggestions???

Thanks,
Dave

Well, I solved it... The key was in this sentence in the Ant docs for
the jar task:

The extended fileset and groupfileset child elements from the zip task
are also available in the jar task.

Which enabled me to do this:

<property name="top.dir" value="/javasrc"/>
<property name="util.dir" value="my/stuff/util"/>
<property name="Proj1.dir" value="other/stuff/Proj1"/>
<property name="jar.file" value="Proj1.jar"/>

<target name="jar">
<jar destfile="${top.dir}/${jar.file}">
<zipfileset dir="${top.dir}/${jws.dir}" prefix="${util.dir}"
includes="*.class"/>
<zipfileset dir="${top.dir}/${jcw.dir}" prefix="${Proj1.dir}"
includes="*.class"/>
</jar>
</target>

The jar task specifies no contents, and each of the zipfileset elements
specifies a directory, and prepends the path when the files are stored.

cheers,
Dave

check out genjar. It makes sure you have not forgotten anything or
including stuff that does not need to be there.
