Eclipse project import error: some projects were hidden because they exist in the workspace directory

Sometimes, when we import an existing project, an error occurs, and the next button is not displayed. The error message is as follows: some projects were hidden because they exist in the workspace directory.

After reading this article for a long time, many Chinese websites did not see any feasible explanations. I accidentally saw it on a foreign language website. At this time, it seems that English is particularly important!

The cause of this error is that the project name is duplicated! It is not just a folder name. I believe many people have modified the folder name, but it is useless. The key is to modify a file in the project! That is, the. project file! Open it in notepad and modify projectname in <projectdescription> <Name> projectname </Name>. If it is imported again, it will be OK.
