[rules-dev] Upgrade to maven 2.2.1 from maven 2.0.9 + upgrade maven plugins?

[Geoffrey De Smet]

Hi guys,

Our maven build could use some cleanup.
I think now is the time, before the m2 and rc releases are being build,
and much of the build will be used thoroughly.

Drools has a minimal maven version of 2.0.9.
Hudson uses maven 2.0.10 for drools.
Some developers are already using maven 2.2.1 (that's the default in 
Ubuntu 9.10 and probably will be Fedora 13 too).
Maven 3 will be released Q1 2010, though they claim that maven 3-alpha-5 
is already the most stable maven ever build.

So, currently we are suppose to make sure our build works and builds 
exactly the same on these maven versions:
   2.0.9, 2.0.10, 2.1.0 (this version sucks), 2.2.0 and 2.2.1.
It probably doesn't.

I'd like to take a look at 2 things:
- Upgrade minimal maven version to maven 2.2.1
- Upgrade maven plugins (some use really old versions)


So, the first road block (if we want to do this) is hudson.
Can the maven version of hudson be specified per project?
Or do we have to wait until jboss upgrades the overall hudson maven version?
