I'm sorry, I know that question is asked quite often. But non of the scenarios suits my problem.
I'm using Eclipse (in Win7) with Git. Within a Git-branch I created a new project. Then I switched back on the master-branch. There the project is not in the workspace. But when I want to add it, I get the following error:
Some or all projects can not be imported because they already exist in
Use "file" --> "import" -->"Existing Projects into Workspace" to import the Project that exists on your HDD
