to create the eclipse update site just call:

'mvn install' 

this will create a folder:

'<project-dir>/updatesite/site.dir/'

this folder includes the 'site.xml' which is needed by eclipse to install a new feature.

To test the update site generation just point your eclipse update manager to this folder,
by specifying a new "local update site".

by now (2008-10-13) the feature generation is realised through a single stand alone maven
project located in the teamweaver svn trunk with the following name: 

'org.teamweaver.is.eclipse.feature'

this is because maven and its plugins lag of support for generation of eclipse features. 

To Change s.th. in the feature you have to change the 'feature.xml' located in the extra
project above. And install/ deploy the changes to the maven repostory.

The 'features' folder an all its contents included in this project(org.teamweaver.dist.is.eclipse)
are disabled and just keep here for documentation.
