I've started research on developing for Eclipse. My intention is to make a suite to aid in the development of my custom game library. I have successfully created a "Hello World" example and am able to run successfully. I am adding to the project to test the eclipse plugin api, however, when I type IProject or IFile, both cannot be resolved to a type. I have tried Ctrl+Shift+I to auto-import, but no libraries are imported. Can someone please point me in direction where I might find the api / libs / jar / whatever to reference? Thanks
These classes are in the org.eclipse.core.resources plugin. You must add this plugin to the 'Required Plug-ins' list on the 'Dependencies' page of the plugin.xml/MANIFEST.MF editor.
Note that you can only use these APIs in a Eclipse plugin, they can't be used in a plain Java project.
