The best answers to the question “Some projects cannot be imported because they already exist in the workspace error in Eclipse” in the category Dev.
I am trying to import a project that me and my co-worker have been working on.. and keep getting this error after I select– “import” then “import existing project” then click archive file, and then I click next, and this error comes up:
“Some projects cannot be imported because they already exist in the workspace”
go to .project file in your project and change the name of the project in name tag
Uncheck the “copy projects into workspace” checkbox, and then click “refresh” button, you will be able to import the project
This usually happens when you change the project directory physically without first delete in Eclipse.
You can view and delete these hidden projects in the following view:
Window -> Show View -> Other -> General -> Navigator
Then simply just continue with the process of import existing project.
It has just happened to me too. Finally I realized that the project was already open in my workspace but it was not visible because of the selected working set. You have just to deselect the active working set and all opened projects will become visible.
