Hi, I just svn checkout xwiki from *** http://svn.xwiki.org/svnroot/xwiki/trunks** and follow the document http://dev.xwiki.org/xwiki/bin/view/Community/Building to build it. I get the following error: Missing: ---------- 1) com.xpn.xwiki.platform:xwiki-build-xar-handlers:jar:1.8-SNAPSHOT Try downloading the file manually from the project website. Then, install it using the command: mvn install:install-file -DgroupId=com.xpn.xwiki.platform-DartifactId=xwiki-build-xar-handlers \ -Dversion=1.8-SNAPSHOT -Dpackaging=jar -Dfile=/path/to/file Path to dependency: 1) com.xpn.xwiki.platform:xwiki-externals:pom:UNVERSIONED 2) com.xpn.xwiki.platform:xwiki-build-xar-handlers:jar:1.8-SNAPSHOT ---------- 1 required artifact is missing. for artifact: com.xpn.xwiki.platform:xwiki-externals:pom:UNVERSIONED from the specified remote repositories: xwiki-releases (http://maven.xwiki.org/releases), central (http://repo1.maven.org/maven2), xwiki-snapshots (http://maven.xwiki.org/snapshots), xwiki-externals (http://maven.xwiki.org/externals) Any clue?
