I have a project with multiple modules, each in its own directory. Each module has its own ant build file (build.xml)
In the root directory I've set up a general build file that calls the build file of each module in the right order.
<?xml version="1.0"?>
<project name="bridgedb" default="all" basedir=".">
<target name="all">
<ant dir="corelib"/>
<ant dir="tools"/>
<ant dir="makeGdb"/>
<ant dir="cytoscape-plugin"/>
</target>
</project>
Now each module also has a "clean" target, so I add these lines:
<target name="clean">
<ant dir="corelib" target="clean"/>
<ant dir="tools" target="clean"/>
<ant dir="makeGdb" target="clean"/>
<ant dir="cytoscape-plugin" target="clean"/>
</target>
And there are more targets like that. Is there a way to rewrite the build file to avoid this duplication? I've looked for a built-in property that contains the active target, but I couldn't find it.

Put one clean target in your commonbuild.xml and in the child files just import your parent build.xml
<import file="${parent.dir}/commonbuild.xml" />
Now you will be able to call the clean target in your child builds. You can also override this target by creating a clean target in any of your child builds.
amarillion : If I understand this correctly, that assumes that the "clean" target does exactly the same thing in each subdirectory. But that is not the case, especially not for other targets that I may wish to call in the same way.Nuno Furtado : You are correct i misunderstood your question.amarillion : np, this is a useful trick too that I may use some other day :)Tazzy531 : [http://www.exubero.com/ant/dependencies.html](http://www.exubero.com/ant/dependencies.html) <-- I just implemented this in my build environment. Makes everything very clean and simple. I have one main build-common.xml and if I need to override the main, I just do it in the build.xml in the submodules. -
Why not use antcall to call a target that references all your subdirs, and parameterise the target to be called. e.g.
<antcall target="doStuffToSubdirs"> <!-- let's clean --> <param name="param1" value="clean"/> </antcall>
and then:
<target name="doStuffToSubdirs"> <ant dir="corelib" target="${param1}"/> <ant dir="tools" target="${param1}"/> ...etc </target>
so this allows you to parameterise the calls to your subdirs. If you add a new subdir, you only have to add that subdir to the 'doStuffToSubdirs' target (I would rename that as well!)
amarillion : Yup this works, thanks.amarillion : although it should beBrian Agnew : I'll correct that now. Thx for the heads up (I confess I didn't test that :-)
