I have org.eclipse.platform_3.8_155965261 installed in my pc and yesterday I upgraded my linux mint 18.3 to 19. after that eclipse stopped working showing error message

An error has occured. See the log file

I have reinstalled it but it was not Beneficial. tried this but that's also worth.

This is the log

Bug #891956

This sounds like your issue, titled: Debian Bug report logs - #891956 eclipse no starting -ClassNotFoundException: org.eclipse.core.runtime.adaptor.EclipseStarter.

the suggestion in that bug was to do this:

$ sudo apt-get install --reinstall libequinox-osgi-java

The debug output claimed that the framework has been found, but this was a lie since: /usr/lib/eclipse/plugins/org.eclipse.osgi_3.8.1.dist.jar was missing.

Bug #898086

Based on the stack trace there's also this bug titled: Debian Bug report logs - #898086 Missing symlink of org.eclipse.osgi jar.

This looks like your exact issue. This particular bug is still active and has no resolution or workaround.

  • @UjjwalSingh - another bug, has your stack trace, the bit about the missing link, maybe make that manually? – slm Jul 17 '18 at 4:05
