I checked in eclipse/java plugin project from svn repository.
Eclipse automatically builds the code to show hundreds of errors.

It seems like that eclipse doesn’t properly link to the plugin libraries. Googling to find this site that I need dependencies and other tabs in plugin.xml.

What might be wrong? I use Indogo(3.7) on Mac OS X 10.7.4
I used Indigo (3.7) for my Mac, but it happened so that the plugin was built on Helios (3.6). When I run the plugin using Helios, I got the project compiled without errors.
It seems like that some of the plugins are (heavily) version dependent.
