I am trying to install Green UML on eclipse(version 3.8), but there are some errors listed below. Anybody know how to solve it?

"Cannot complete the install because one or more required items could not be found. Software being installed: Green 3.5.0 (Green.feature.group 3.5.0) Missing requirement: Green 3.5.0 (Green.feature.group 3.5.0) requires 'org.eclipse.draw2d 0.0.0' but it could not be found"

When you are installing something in Eclipse, at the moment of choosing what will be installed, mark the option :

Contact all update sites during instal to find required software

Also, you should be sure that you have all update sites set. Go to Work With field and check sites. You should have there:

If you don't have these sites, write them both into the field.

The package org.eclipse.draw2d is one of three main components of GEF. The GEF is on the first site, so, the problem should be eliminated. You need only to revert the last installation (help-about- installation details - installation history- the previous installation - revert), restart Eclipse and repeat the installation.

  • Thank you for your answer. I tried your way to do it, but it still doesn't work. I can not even move to next step since it can not find http://www.cse.buffalo.edu/faculty/alphonce/green. – user3352920 Mar 05 '14 at 04:26
  • @user3352920 And why do you install by hand? read http://green.sourceforge.net/builds.html and install normally, from the address given there. – Gangnus Mar 05 '14 at 09:11
  • what do you mean by installing by hand? What i did is exactly according to the link you showed. Is that right? – user3352920 Mar 06 '14 at 06:31
