i added eclipse cdt 8.4 update site (http://download.eclipse.org/tools/cdt/releases/8.4), retrieves version 8.4.0.201406111759, same version luna update site, , error same:

an error occurred while collecting items installed session context was:(profile=epp.package.jee, phase=org.eclipse.equinox.internal.p2.engine.phases.collect, operand=, action=). no repository found containing: osgi.bundle,org.eclipse.net4j.jms.api,3.1.100.v20140218-1709 

how can install eclipse cdt in eclipse luna instance?

pd: eclipse forums not accepting credentials of eclipse account, not post question there.

finally solved problem. using oracle java 6 execute eclipse. after upgrading oracle java 8, installation process executed correctly.
