[Proposal] Switch to using Maven2

Hi, I'd like to propose 2 things: 1) Use Maven2 to perform the 1.1M3 release 2) Remove the Ant build in 1.1M4 Rationale: * It's a real pain to maintain 2 builds * The m2 build is already doing more than the Ant build Things left to do on the m2 build: * Finish setting up TeamCity (I need Raffaello's help as ObjectWeb's SVN is bad and we need to set up a SVN ready only replicate on which we could plug TC) * Fix an issue with the database importer (XWIKI-1104) * Review the versions of the dependencies What this means is that you should try using Maven 2 yourself from today onward and see if can make it work. If not, ask questions here on the list and I'll help and I'll tune the build accordingly. There's already some doc on: http://www.xwiki.org/xwiki/bin/view/Community/ Building#HBuildingwithMaven2 WDYT? Thanks -Vincent
