I'm well aware of this, but this is just to ease things in the future. 
It shouldn't stop anything happening now.

Moving around is always going to be a problem.

I still don't get how Magic does this. Would "ant" declare that it is 
also "jakarta-ant" so that projects looking for "jakarta-ant" find the 
right thing? How does this get fed to gump?

Anyway, I added dependency properties so that projects can control their 
own destiny. This means if a project changes names, its dependees will 
all break, but I think they'd want to know that anyway.


With that, the gump descriptor should not need to be hand edited.

According to the documentation, it was for classpath generation. 
Shouldn't be needed.

Yes, it does it like you had previously done it for eve. One module, 
many projects.

This is what matching the IDs will buy eventually.

So, does eve/trunk/gump.xml now look correct to you? Is there anyway we 
can get it to run and find out?

If there is anything else you want to discuss about the changes I made 
for Maven/Gump, we should probably take it over to the gump list...
