Hello, I checked ou trunks yesterday night with an empty maven repository in console mode... Then I launch "mvn install -Pmysql" 1)It then blocks immediately because in trunks/pom.xml, the parent pom is xwiki-platform-pom/pom.xml with version "14-SNAPSHOT" but current version is "15-SNAPSHOT". To go quickly, I change xwiki-platform-pom/pom.xml to version 15-SNAPSHOT... 2)I relaunches and it blocks again because it can't download xwiki-xar-handlers version 1.9-SNAPSHOT (apparently it doesn't try to compile xwiki-platform-tool before looking elsewhere). So I go in xwiki-platform-tools/xwiki-xar-handlers and I run "maven install" and I get my 1.9-SNAPSHOT 3)I relaunches and it goes on until xwiki-platform-plugins/lucene... I get lots of "unknown symbol" Maven downloads into repository lucene/lucene/1.4.3 and org/apache/lucene/lucene-core and lucene-parent version 2.3.1 If I remove lucene/lucene/1.4.3, it resynchronizes it and then it works... I had this problem last week when I compiled from an empty maven repository also... Maybe a problem while downloading lucene-1.4.3 first time and this gives a bad Jar file... Anyway not a real problem 4)I relaunches again and it goes on until xwiki-platform-core/xwiki-velocity which fails due to TEST errors: org.codehaus.plexus.component.repository.exception.ComponentLookupException: Unable to lookup component 'org.xwiki.velocity.VelocityManager', it could not be started at org.codehaus.plexus.DefaultComponentLookupManager.lookup( DefaultComponentLookupManager.java:156) I haven't been looking in the project but I wonder if anyone had the same pb as me... 5)So as I don't care about tests now, I relaunches with "maven install -Pmysql -Dmaven.test.skip=true" and then it runs until "BUILd SUCCESSFUL" Next step: run it... Next step: do it from Eclipse (I get lots of Java Heap Space problems with M2Eclipse 0.0.12) Pascal
