Subject Re: Best way to perform this type of conditonal test in ANT
Date Fri, 21 Sep 2007 13:48:46 GMT
The "ant" way is not to think in terms of calling targets,
it is more in-terms of invoking a target, and the
target reads it's dependences.

In ant 1.6 the unit of reuse/encapsulation/block would be a macro.

I would use a macro instead of each of your pmd targets, and
call them directly from the pmd target.

...
However with <antcontrib> the runtarget does not
set up a new ant project context, so the properties
set in them are visible afterwards, so there
must be something else wrong with your script.

For example:
<project default="abc" xmlns:ac="antlib:net.sf.antcontrib">
  <target name="abc">
    <ac:runtarget target="runme"/>
    <echo>${set_in_runme}</echo>
  </target>
  <target name="runme">
    <property name="set_in_runme" value="hello world"/>
  </target>
</project>

Buildfile: /work/reilly/learning/a/runtarget/build.xml

abc:

runme:
     [echo] hello world

BUILD SUCCESSFUL
