I think this is a good suggestion. While I was setting myself up to be 
able to read/compile the sources, I really had little need to use Maven 
- build.xml is enough to compile and test the math project (and I 
assume Maven uses this as part of the process in creating a jar). 
Still, from what I can see, Maven might have uses for things other than 
just creating the web site and release builds. It downloads correct 
versions of all dependency jars, saving a little bit of work. Also, I 
imagine that if somebody makes documentation changes, they would need 
to do a 'maven site:generate' to see what the changes actually will 
look like.

Although I'm new here, this thread kind of started because of my 
question. So my suggestion is that (perhaps in the Developer's Guide), 
using just build.xml for development should be encouraged. But for 
people who want to use Maven (for some reason or other), there could be 
instructions that say exactly which files/directories need to be 
checked out from jakarta-commons in addition to the 
jakarta-commons/math module. This won't reduce external Maven 
dependencies, though. If there really is a desire to reduce external 
dependencies, could a second project.xml file be created in math that 
removes references to '../project.xml'? Then Maven could be called with 
'maven -p onlymath.xml' (unless I misunderstand the -p switch), and 
this would be used only by developers who want less to download from 

Anyway, just my 2 cents.
