Eclipse is throwing the following error when I check for updates:
An internal error occurred during: "Searching alternate solutions...".
org.codehaus.groovy.eclipse 2.6.1.xx-20120301-1300-e36-RELEASE is unknown in the solver!
I have searched and checked this related question, but I do not have the mentioned package installed. Neither anything is getting listed when I search for groo/java 8 etc in the installed software.
If I just ignore the groovy plugin update listed (and marked in error), and try to continue with the update, I am getting below error while updating software:
An error occurred while collecting items to be installed
session context was:(profile=epp.package.jee, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).

Eclipse Version: Neon Release (4.6.0) and Build id: 20160613-1800
How do I fix this?
