Ant break

[Stephen Felts]

I'm seeing a problem using ant that I suspect is related to the classloading.  I think it came in build 107 or 108.

The following 

  <path id="modules.antcontrib.classpath">
    <pathelement location="${build.install}/ant-contrib-1.0b3.jar" />
  </path>
  <taskdef resource="net/sf/antcontrib/antlib.xml" classpathref="modules.antcontrib.classpath" />

Is failing with

/mydir/build.xml:27: taskdef class "ignore"/> cannot be found
 using the classloader AntClassLoader[/mydir_build/ant-contrib-1.0b3.jar]


This would seem like a pretty common use case.

If I comment that out, then I get the following.  The named class is in the specified jar file.


/mydir/build.xml:578: typedef class name="p4versionstring" classname="weblogic.ant.taskdefs.perforce.P4VersionString"/> cannot be found
 using the classloader AntClassLoader[/mydir2/weblogic.ant.taskdefs.perforce_1.1.0.0.jar]
