Eclipse - Error occurred at launch / see log file

Question

Ok, I have a Java presentation to provide this morning and here I am in front of the audience, not able to load Eclipse with no "obvious" error to fix it quickly in a humane way without crawling in forums and going through the whole debugging process.

If somebody knows how can I upload the whole error log file let me know, as it still goes for pages.

I searched through the web and the possible culprits seem to be so numerous, so I try yet-another SOS here (each case seems to be so user-specific)

Any help or hint about how to solve this issue is very welcome.

Please consider asking questions before downvoting, some people tend to be quick shooters.

PS (off-topic) : I've been coding on this IDE for 15 years and I find it unacceptable to still have to debug your own IDE instead of spending time being productive on your core code, not to mention public embarrassments like the one I am going through now.

I never have this in Visual Studio for example. This IDE is too fragile to be considered "normal", acceptable, and an industry professional level. I really like eclipse but this aspect is a curse.

Answer 1

A couple of options

1. Have you tried starting eclipse with the argument -Dosgi.locking=none?
2. Delete the lock files under the eclipse directory configuration/org.eclipse.osgi/.manager
