Simplify build profiles and make the default profile faster

From mailing list:

I 'd like to refactor the maven build to use exactly 3 profiles and remove all other profiles:

• default
  o Fast, for during development
• full
  o Slow, but builds everything. Used by hudson, releases and before you go to sleep
• soa
  o Prunes the non-soa stuff away

What do you think?

Long explanation:

• The maven build is too slow atm:
  o GWT compilation of all permutations (during development 1 permutation is enough)
• yet some parts of the code don't build with maven
  o such as
  + in the past GWT compilation
  + antlr generation
  + eclipse plugin
  + examples
  o problems with this approach
  + they use unmanaged dependency versions (antlr generation might use a different version than antlr dependency in pom)
  + require tool installations (gwt dev kit under /home/Rikkola/gwt
  + commit generated files to svn
  o adding them to maven will make the maven build even slower... unless...

The profiles are too complicated, currently we have these profiles:

• default (the one you run with "mvn clean install")
  o Build these too
  + drools-clips
  + drools-planner
  + drools-pipeline
  + drools-simulator
  + osgi-bundles
  o Proposition: don't build those in soa
• documentation
  o Build drools-docs too
  o Proposition: merge into profile full
• build-eclipse
  o Build drools-eclipse too
  o Proposition: merge into profile full
• cibuild (hudson)
  o Build these too:
  + drools-docs
  + drools-eclipse
  + drools-examples too
  o In drools-process, build these too:
  + drools-bpel
  + drools-jpdl
  o Proposition: merge into profile full
• soa
  o in drools (parent)
  + assembly: use soa assembly description alternatives
  o in drools-guvnor
  + change some tokens in some files (ant based, not maven filtering yet)
  + run pre-integration-test
  o in drools-eclipse
  + Don't build org.drools.eclipse.task
  o in drools-docs
  + Don't build drools-docs-planner and drools-docs-integration
• grammars
  o in drools-core and drools-compiler
  + runs the antlr file generation
  o Proposition: replace with maven antlr plugin
  + if fast, do part of the default profile and output to target dir
  + if slow, do part of the full profile and output to src dir (just as it is now)
• gen-brms-import (not part of any top-level build)
  o Proposition: Leave it alone until we deal with that commented out module bulk-importer-util
• ydoc-doclet (commented out on drools parent pom)
  o Proposition: remove it
