Downloaded update zip from http://download.jboss.org/jbosstools/builds/nightly/3.1.0.RC1/200912141523/all/JBossTools-Update-3.1.0.v200912141523M-H176-RC1.zip

Download fresh eclipse from eclipse.org

Added the updatesite zip
Added m2eclipse update site

Tried to install All features (excluding birt and tptp and SDK's)

And received this error - only when I installed m2eclipse first did it want to go pass this:

Cannot complete the install because one or more required items could not be found.

Why are we depending on 0.0.0 ? ( I assume that is the problem )
And shouldn't this work if m2eclipse is available as an update site ?
