BUILD.txt

Build system: 

JDK required: 1.5+
Maven (http://maven.apache.org) required: 2.0.9+

Build profiles:  

- default: builds all releasable modules
- reporting:  builds reports and javadoc/source attachment of artifacts
- distribution:  builds distribution
- nt: no-test, builds skipping unit tests 

Note:  profiles are additive and the default profile is always active.
Eg, build with reporting and distribution:

mvn -Preporting,distribution install

IMPORTANT NOTE ON REPOSITORIES: 
Some dependencies are not synched with central maven repo.  
Rather than configuring lots of remote repositories to the root POM, which implies lots of redundant lookups to several remote servers, 
it is the responsibility of the user building the code to ensure that these are configured in the user ~/.m2/settings.xml, as profiles, 
and then build (just once) with the corresponding profiles to retrieve the dependency.  
A good practice is to leave a note next to dependency declaration where it is found, if not in central repo.
Another option is to define a picocontainer profile with all the remote repositories needed by project and activate it on demand.
A settings.xml template is found at http://svn.codehaus.org/picocontainer/java/2.x/trunk/pico/distribution/src/config/settings.xml.
