In Gump's case the "dated version snapshot builds" are less controlled
- and this is where I expect problems to come up.
commons-collections-20040102 is compiled against commons-lang-20040102
and may not work with commons-lang-2.0 at all.  This is a completely
fictuos example.

I'm all for coordinating this.

And as I already said, Gump can publish the created jars right now,
it's all a matter of how we get them from say the machine
(or a future into the directory layout you envision.

you don't want to rule out projects that build with vanilla Ant, do
you ;-)

For all projects that build successfully in Gump except for
bootstrap-ant you can assume that they have a working build.xml that
creates the jars.  Which targets Gump executes is completely under
control of the project - or whoever takes care of the metadata
describing it.

This is nothing Gump can enforce.  Traditionally Gump has been picking
up the build files as they are, injected properties to its liking and
tried to figure out which target to invoke.  I don't think you'll ever
get all projects built by Gump to follow any target name convention at
