Installing Eclipse

Question

I am installing Eclipse for RCP and RAP Developers, my old copy went rogue and decided to act up.

So clean install time! Yay! I downloaded the new version copied it to opt folder and extracted it, then ran it.

For some reason I cant install any plugins due to some crap error*, and it doesn't have list of default plugins, i deleted my workspace and the original eclipse install.

If there is another file that is helping it keep data from previous installs, because i am seeing update sites i added, when i was constantly trying to get past this issue.

Also Why can't I install new plugins?

I need a clean install so I can't use the Ubuntu installer.

Any tips are appreciated.

*Cannot complete the install because one or more required items could not be found.

Answer 1

I had the same problem when doing a fresh install of jee eclipse (helios, galileo, win32 and win64).

The solution for me was to explicitly open the Java perspective, and doing the install after this. This time the installation worked fine.

I suspect the reason is that after a fresh install not all bundles are loaded (although they are present on disk; a feature of eclipse) so that the dependencies cannot be resolved. Opening the Java perspective or creating a dummy Java project will force to load these bundles. Once a bundle is loaded, its existence is persisted, so this only has to happen once.

This issue was mentioned a number of time on the official websites, but always closed or neglected, probably because the reproducer did not do a fresh install.
