All:

I am trying to invoke an Ant build from within a java program. The build=20
system itself includes both:
=2D a namespace declarations (<project xmlns:ivy=3D"antlib:fr.jayasoft.ivy.=
ant") -=20
=2D an <import task.

=46rom what I can gather, the basic sequence for invoking ant is the follow=
ing:
project =3D new Project()
project.init()
helper =3D ProjectHelperxxx()
helper.parse( ant, File(<buildfile>))

The API docs reference 2 helpers - ProjectHelper2 and ProjectHelperImpl. I=
=20
can't get either to work.=20

If I use ProjectHelperImpl the parse fails with an "Unexpected attribute=20
"xmlns:ivy" error. If I remove the remove the namespace declaration the par=
se=20
suceeds

If I use ProjectHelper2 then I avoid the namespace error, but the import fa=
ils=20
with a null pointer exception and an unknown element error.

Anybody have any clues/hints on what I am missing?

Thanks!
