Hi,
I'm designing a plug-in and i need to get the workspace's path; so i'm
trying some code;
IWorkspace workspace = ResourcesPlugin.getWorkspace();
..
..
But first, i could not import library of "IWorkspace" and
"ResourcesPlugin".
i tried adding this library to my eclipse by;
project-> properties -> java build path -> add external jars
so i added; -found them in "C:\Program Files\eclipse\plugins"-
org.eclipse.core.resources.win32_3.3.0.v20070226.jar
org.eclipse.core.resources_3.3.1.R33x_v20080205.jar
org.eclipse.core.resources.compatibility_3.2.100.v20070502.j ar
now i can import their library "org.eclipse.core.resources"
But when i try to run the code, i get the "Class can not be found" runtime
error.
Can someone tell me where is the problem ? and how can i fix it ?
Or is there a way to get the workspace path without using this library?

Cumhur,
This is a recurring error that I see again and again. When building
plugins, don't ever mess with the classpath directly via the properties
of the project. Only edit the MANIFEST.MF and change the dependencies
in the Dependencies tab. Otherwise, the compile time problem you fix
will come back again at runtime.
