[xwiki-devs] Problem building XE

Hi guys, I have a problem running XE and can't solve it by myself. I have checked out the source, and did mvn install, and if I understand the Building documentation correctly this should be enough to run XE (I'm new to maven). But after the building ends (with status BUILD SUCCESSFUL), I have no jetty running. Also, near the end of build process such message shows up 4 times: [WARNING] Cannot include project artifact: org.xwiki.enterprise:xwiki-enterprise-jetty-hsqldb:pom:3.0-SNAPSHOT; it doesn't have an associated file or directory. I also tried to deploy the generated WAR but after opening up the webroot in browser a hibernate exception shows up about error in configuration file (I believe it can be related to the above). Also, when I tried to build XWiki Platform, it also succeeded, but when trying to quickly deploy app as in instructions (mvn install -Pjettyrun), I got a message about missing archetype, with name looking like not-processed or something: ${xwiki.db.jdbc.groupId}:${xwiki.db.jdbc.artifactId}:jar:${xwiki.db.jdbc.version} I followed the wiki instructions exactly, what am I doing wrong?
