You need to set ant.home Java property, not the environment variable, if you want to launch ANT yourself.

I am playing around with executing Ant targets from Java code.

Here's what I am trying to do (based on what I've seen in mailing list posts)...

      public static void main(String[] args) {
                ProjectHelper ph = ProjectHelper.getProjectHelper();
                Project p = new Project();              
                ph.parse(p, new java.io.File("build.xml"));
                System.out.println(p.getBaseDir());
                System.out.println(p.getDefaultTarget());
        }

But I get ...
Exception in thread "main" build.xml:6: Could not create task or type
of type: description.

The $ANT_HOME env var is set and I have all of the $ANT_HOME/lib dirs
on my classpath. So, either that's not the way to create an in-memory
version of a build script that can be called from code or there's
something more I need to do with my classpath so that the
ProjectHelper can find all the JARs.

Can anyone point me in the right direction?

thx
andy
