If I install a default eclipse from the ubuntu program central, I get an eclipse with traces from the version Helios and the screen that starts Eclipse says Indigo. The latest version of Eclipse is called Juno. It's possible to download a separate download of eclipse juno and run it and link as mentioned:
How do I install Eclipse Indigo 3.7.1?
But the Eclipse available from the central ubuntu reposotiries could update to version 4 (Juno) and then we would not have to do the manual install. Or how do I update a manual install? I can't update the default install to Juno.
