Setting up Xwiki for development

Greetings! I'm currently working on my master thesis, I've chosen XWiki as the wiki system that will support my platform. I used the Windows Installer in http://www.xwiki.org/xwiki/bin/view/Main/Download and easily set up a local xwiki instance, in order to explore it and learn how it works. But I shall probably have to adapt or create some functionality related to the Audit requirements I have defined (I'll save this for future posts ;) ), so I'd like to set up a development xwiki project using Eclipse. I followed the instructions in http://www.xwiki.org/xwiki/bin/view/Community/BuildingInEclipse: I checked out the source from the trunks-devs, ran mvn eclipse:eclipse and created a new eclipse workspace, which I included in a new variable M2_REPO. Finally I created a java project and did an import from the folder with all the code (xwiki-platform-tools, xwiki-platform-core, xwiki-platform-web, xwiki-platform-plugins and the others). The result was 22070 errors and 390 warnings in the 'Problems' tab! I think I must have missing something related to the building process.. being my first experience with eclipse, besides the tutorials, surely doesn't help! Could you guys help me? Thanks in advance and congratulations for the xwiki platform. I hope I can contribute with some code or plugins :) Best regards, Ricardo Pinto. Ps: By the way, I'm using Windows XP, Eclipse 3.2, JDK 1.5.10, Tortoise SVN (and will use mySQL after setting up the IDE environment).
