There are many projects in the package explorer view so I deleted some from the view (not on the disk). Now, I want to reopen a project in the same workspace. I use import -> existing project into workspace -> select root directory and find my project. Then, I somtimes got: "Some projects cannot be imported because they already exist in the workspace", which didn't allow to open the previously no-show project. But sometimes, I could. Can someone tell me what is the correct way to reopen a project in the same workspace. Thanks.
