Solve the Problem of overlaps the location of another project in Eclipse: 'xxxx'

New-> Android project-> Create project from exist Source
The following error message is displayed:
Invalid Project Description
------> Detail:->>> xxxx (Project path) overlaps the location of another project: 'xxxx'
I finally found out why I put the source code under the workspace directory.
When creating a project, the Eclipse plug-in needs to create a directory with the same name under the workspace directory.
However, if the corresponding directory already exists in the workspace directory, the error message above will be reported.

The solution is simple: Move the source code package to a non-workspace directory.
