[virgo-dev] Virgo maven build
Hi All,

I finally got some time and attached is the result of some prototyping.

Attached is the master.pom - lock down versions of plugins and artifacts used across all projects.
Also to provide some place for common properties and version variables.
(see attached pom.xml)

I decided to work in the dependency order (i.e. http://wiki.eclipse.org/Virgo/Build#.22Rippling.22).
So I started with osgi-test-stubs.

The results of my experimentation is maven-squashed.patch (attached).

So issues I ran into:
1. Could not get maven-compiler-plugin with compilerId = aspectj (http://maven.apache.org/plugins/maven-compiler-plugin/non-javac-compilers.html) to work
2. #1 means that we really can't do "exactly" what osgi-test-stubs build is doing, i.e. compiling with iajc. What I got working is the virgo-build/weaving approach. Compile with jdt and call iajc on compiled code.
3. Bundlor usage is a bit unfriendly with maven. Especially for webapps. (see comments in master pom.xml)

Top two issues ate most of the time. I pulled down sources for all of the related plugins and to be honest - each and everyone of them is in need of some TLC.

What worked:
1. tycho-compiler-jdt works well and allows override of jdt compiler version. (Should jdt compiler be updated from 3.3?)
2. generated class files are identical in size
3. tests run and pass building both ways.

I will continue on modifying all other projects and post back with results.

Regards,
Dmitry
