Open the Terminal and go to the location where eclipse is installed.

If you have any shortcuts on the desktop youll have to remove them and make new shortcuts with the executable.

Eclipse Java 7 Archive The Tar

I was using The Unarchiver 3.3 to unarchive the tar.gz archivethis was the problem.

I right clicked the archive and selected Open With Archive Utility.app (10.8).

Very strange, The Unarchiver has never let me down before but this seems to be the problem.

An older version is known to corrupt files on extract under certain circumstances.

Then I find out that the reason is I am trying to run Eclipse from a shortcut link, so I delete that and then back to Eclipse root folder and make an Alias from the Eclipse file and then I send it to desktop and now running very well.

Instead of running the eclipse app from the Applications folder, simply run it from the original eclipse folder to avoid the error.

I solved this by moving whole eclipse folder(not the eclipse shortcuteclipse executable) to application.

To solve it, I had to remove the eclipse executable in the application folder and replace it with a link to the one inside the Eclipse.app folder.
