pm.setShowSubTaskChanges(true);
pm.forceRefreshInterval(-1);
IWorkspace workspace = ResourcesPlugin.getWorkspace();
IWorkspaceRoot rootWorkspace = workspace.getRoot();
// IProject project = rootWorkspace.getProject("Sunopsis
Beans");
// IPath workspaceFolder = rootWorkspace.getFullPath();
File directory = new File("C:\\work\\odi_11g\\Sunopsis Marker
Icons");
ImportOperation importOperation = new ImportOperation(
rootWorkspace.getFullPath(),
directory,
FileSystemStructureProvider.INSTANCE,
OVERWRITE_ALL_QUERY);
importOperation.setCreateContainerStructure(false);
importOperation.setContext(null);
importOperation.run(new SubProgressMonitor(pm, 1));
I am getting the followign exception

I have compiled my plugin with java 1.4 and compliance level set to 1.4
and am also running it with java 1.4.
The only thing that i did is that i have added the plugins as external
jars to my project in order to get my project compiled as i was not able
to select the particular plugin jar file in the plugin-in dependencies.

Suresh,
When building plugins, don't ever edit the project's build path
directly. You must use the dependencies tab of the MANIFEST.MF editor
to fix your classpath problems, otherwise the problem will just come
back at runtime as you see here.

The file system path from which i am trying to import does have the
project and the .classpath files under it. I am not sure if i understand
this exception.

Hi got past the earlier exception by
just creating an empty project using workspaceRoot.getProject(projectName)
and project.createProject(projectDescription, pm) call
Now the project gets imported into the empty project, however there are
some problems.
1. The project doest not have a java nature attached to it. The .project
file which is copied into the project does have the java nature in its
content.
2. I do not want to physically copy the projects into the workspace
directory, i would like to just link it the actual file system location
where the project is located. I basically just want to register the java
project with the workspace so that when i build the workspace
programmatically it does not say that the resource does not exists.
The ImportOperation seems to be a utility for importing some external
content into an existing project.
What i want is to be able to import an external existing project into the
workspace without actually copying it and without UI

Suresh,
When you "create" a project you can specify the physical location for it
in the project description...
