"overriding" a target

["Combs, Clint" <cl...@contrado.com>]

Hi,

My company is using ant for all our Java builds.  We have a primary build
file, called common.xml, and all include files named project-name.xml
include this file via a line like:

<!ENTITY include.commontasks SYSTEM "file:./common.xml">

This works great, but I have a project where I'd like to extend the "clean"
target that is found in common.xml.  In other words, I'd like to define the
"clean" target in project-name.xml to do everything in common.xml, plus a
few more things.  Obviously, I could define another target name which
depends on clean, but that would break the overall build process, which
calls clean automatically on each project.

I saw discussions of extending tasks on this list a while ago, but nothing
about overriding/extending targets.

Is this sort of feature available now?  If not, does it sound like a
reasonable idea?  Would it be possible to add this?

Thanks,
Clint

How about the approach described below?

common.xml:

  <property name="clean.target" value="clean.commontasks" />

  <target name="clean">
    <antcall target="${clean.target}" />
  </target>

  <!-- The common clean target: -->
  <target name="clean.commontasks">
    <echo message="Now executing commontasks clean..." />
  </target>

The project build.xml:

  <?xml version="1.0"?>

  <!DOCTYPE project [<!ENTITY common SYSTEM "file:./common.xml">]>

  <project name="myproject" default="test" basedir=".">

    <!-- Comment this out and clean.commontasks will be called: -->
    <property name="clean.target" value="clean.myproject" />
	
    &common;

    <target name="test" depends="clean" />
      <!-- The overriding clean target: -->
      <target name="clean.myproject">
        <antcall target="clean.commontasks" />
        <echo message="Now executing project clean..." />
      </target>
  </project>
