If I log out & login again I am able to launch eclipse without the previously mentioned error. I am using Ubuntu 12.04(64 bit).

  • Where is your workspace located? Thanks. – Mochan Nov 5 '12 at 11:13
  • Located on an unmounted disk. Should it be mounted permenantly all the time – shiju87 Dec 19 '12 at 12:06

This message is because there is a previous Eclipse process hanging around interrupting the one you are trying to launch.

ps aux | grep eclipse

find the eclipse process that's still running. I killed both the /usr/lib/eclipse/eclipse and /usr/bin/java processes. The process number is the number immediately adjacent to your user name. Then run

kill -9 [process number]

(without the brackets). That oughta do it!

    I would suggest to try a regular kill first (without the -9 option). A -9 will send a fairly destructive signal whereas a regular SIGTERM will shut it down gracefully (less likely to loose data). – gertvdijk Feb 5 '13 at 16:25
  • @gertvdijk good point – Engineiro Feb 7 '13 at 18:52
