[xwiki-devs] building xeclipse?

Hello, is there a chance for me to succeed at building xeclipse? I tried following http://svn.xwiki.org/svnroot/xwiki/xeclipse/trunk/plugins/org.xwiki.eclipse.... but failed. - it is spoken there about three downloads but two configs in the profile... maybe I goofed there It ended up as:

generateFeature:

BUILD FAILED /Users/paul/tmp/xeclipse/eclise-SDK-3.4/plugins/ org.eclipse.pde.build_3.4.0.v20080604/scripts/productBuild/ productBuild.xml:21: The following error occurred while executing this line: /Users/paul/tmp/xeclipse/eclise-SDK-3.4/plugins/ org.eclipse.pde.build_3.4.0.v20080604/scripts/productBuild/ productBuild.xml:53: Unable to find element: /org.xwiki.eclipse.rcp/ org.xwiki.eclipse.product.

hints welcome paul
