I have builded jboss tools localy and have tried to install RW tools throw local update site under linux.
I have obtained following exception:
An error occurred while collecting items to be installed
session context was:(profile=SDKProfile, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).
No repository found containing: osgi.bundle,com.thoughtworks.qdox,1.6.3.v20081201-1400
No repository found containing: osgi.bundle,org.hamcrest.generator,1.1.0.v20090501071000
So looks like smth broken in our update site, try to wait why we will fix it.
