I have an eclipse plugin application which tries to import an existing
project into the eclipse workspace. Following is the source code
ProgressMonitorOutputStream pm = new ProgressMonitorOutputStream();
pm.beginTask("Create Workspace", 100);
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 you "create" a project you can specify the physical location for it
in the project description...
