How to install plugins on Eclipse

Question

I know there already are other questions like this, but I couldn't find anything useful.

I was trying to install ObjectAid on Eclipse 3.5.1.

I added it to the repository list, then checked ObjectAid UML Explorer. It said:

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 couldn't figure out how to install it.

The operating system is Ubuntu.

Thanks for any help.

That it's in the plugins folder likely means that it IS installed. Can you verify that Eclipse is finding the plugin via Help->About Eclipse->Installation Details->Plug-ins? Make sure it is listed and check the version. The Plug-in name should be "Graphical Editing Framework Draw2d". — Mark Peters

If there is no plug-in with a plug-in id of "org.eclipse.draw2d", but there IS a corresponding directory (or .jar file) in your plugins directory, it's possible that the plug-in is failing to load. Open the Error Log in Eclipse (Window->Show View->Error Log) and see if there are any errors listed where the plug-in is org.eclipse.draw2d. Also ensure that the Eclipse instance you're running is in fact from /opt/eclipse/. — Mark Peters

What's with the org.eclipse.draw2d version being "0.0.0"? Maybe it can't find draw2d because there is no version 0.0.0! — Michael

Have you installed Eclipse from the repositories or from eclipse.org? Have you been able to install other plugins besides this one? I am asking because I ran into problems installing plugins with the Eclipse version from the Ubuntu repository. — ponzao

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/.
