Installing Eclipse

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 the opt folder, extracted it, and ran it.

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

Is there another file that is helping Eclipse keep data from previous installs? 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.

I had the same problem when doing a fresh install of Java EE 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.

Download Eclipse 2018-19 (4.9.0) version as an updated eclipse version and install it! Maven dependency will presented inbuild thing in that model, Right click on project -> properties -> on left pane, Maven will display ! Change your setting there to overcome this error and you can add external JAR'S there
