When i try to run Eclipse Neon, I get an error message saying "An Error has occurred. See the log file F:\path\to\workspace.metadata.log."
Upon viewing the log, I found this:
!ENTRY org.eclipse.recommenders.models.rcp 1 9 2016-07-08 23:06:53.728
!MESSAGE The model index service was accessed either before it started or after it finished running.
!STACK 0
org.eclipse.recommenders.utils.Logs$LogTraceException
at org.eclipse.recommenders.utils.Logs$LogTraceException.newTrace(Logs.java:381)
....
Any ideas what is causing this, and how I fix it? I tried using good old Google, but all I got was that it is a reported bug that has been fixed, yet I am still getting the problem? Reinstalling eclipse didn't fix the problem either.
This is common issue. There are two fixes:
#1
X:\WhereWS_Is\Workspaces\name_of_workspace\.metadata\.plugins\org.eclipse.core.resources\
Here delete .snap file. Eclipse will start normally then.
If not solved then second fix is a bit Heavy as it deletes all preferences etc.
#2
X:\WhereWS_Is\Workspaces\name_of_workspace\.metadata\.plugins\org.eclipse.e4.workbench\
Here delete(not permanently) workspace file. After starting Eclipse, IDE will re generate this file after all setup, paste that file again to get all your preferences.
Both tried, both worked for me. Hope this helps someone.
