I've installed Eclipse with the command:

sudo apt-get install eclipse

or when I install via the synaptic manager.

Unfortunately, when I open up Eclipse I get this error:

Has anyone else seen this issue?

Some succeeded by renaming the ~/.eclipse folder (e.g.

sudo mv ~/.eclipse ~/.eclipse.bak

Note, all plugins will be disabled and you will need to re-install them.

Others (incl. me) did not succeed by doing this. In this case, you have to remove/uninstall the whole platform. You then have to download the package from the official website (and then move for example the extracted package to your /usr/share folder).

Re-installing the IDE via apt-get probably won't work.

I think there is something wrong with PATH environment variable.

Windows XP: http://support.microsoft.com/kb/310519
Linux: http://www.troubleshooters.com/linux/prepostpath.htm
Mac: http://www.tech-recipes.com/rx/2621/os_x_change_path_environment_variable

You need to add the path to the java folder there. After that it should work again as expected.
