How to install plugins on Eclipse

Question

i know there already are other questions like this, but i could't find anything useful. And it's becoming such a painful issue..

I was trying to install ObjectAid on Eclipse 3.5.1.

So, lets google, http://www.objectaid.com shows up. i added it to the repository list, then checked ObjectAid UML Explorer. It says:

Cannot complete the install because one or more required items could not be found.
  Software being installed: ObjectAid Class Diagram 0.9.86 (com.objectaid.uml.feature.group 0.9.86)
  Missing requirement: ObjectAid Class Diagram 0.9.86 (com.objectaid.uml.feature.group 0.9.86) requires 'org.eclipse.draw2d 0.0.0'

I've had a look into /opt/eclipse/plugins and i've found org.eclipse.draw2d_3.5.2.v20091126-1908, but i coudnt figure out how to install it.

The operating system is Ubuntu.

Thanks for any help.

It looks like you didn't install the GEF, which is a requirement for ObjectAid. You can get it at http://www.eclipse.org/gef/ .
