trouble with multiproject

[Glenn R. Golden]

I've got 7 subprojects, and when I run multiproject on them like this:

maven -Dgoal=dist:build multiproject:goal

invoking "dist:build" it runs out of memory, I think.

I've upped the memory from the 256 it's distributed with (maven 1.0 
rc1) to 600m -> 900m.  This in a 1 gig mac 10.3.  It gets further 
along...

Here's the last banner before failure:

+----------------------------------------

Sure looks like running out of memory.

I wonder if a call to GC might be in order somewhere in the 
multiproject processing.  In fact, does anyone know of an ant task I 
could drop into the process which would do a GC?

Has anyone else run into this?  Any go arounds?  Other than doing them 
by hand, one at a time.

Thanks.
