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.
