1 import maven project:
don't put your project source code under the path you plan to setup your project.
For example, if you want to import projects to the workspace path: d:/rds
please don't put the projects source code under d:/rds.
Or the import operation won't succeed.
2 delete projects:
if projects in two workspaces are imported from the same cvs or same code source, when you want to delete projects in one workspace, and the checkbox of deleting files on hardware checked, you will delete the source code in both workspaces.
Be prudent to check the deleting files on hardware checkbox.
