Eclipse import project hints already exist in workspace, but the project has not been imported, because the unexported files have been placed in the imported folder. The specific operation steps of eclipse import project are as follows:

1. First, double-click the eclipse icon to start the program. After opening the eclipse program, click File-Import.

2. An Import window will pop up to enter the Select step.

3. Then select the root directory of the project to be imported, expand the "General" directory, select the existing project and put it in the subdirectory of the workspace, and then click "next".

4. At this point, switch to the Import Project window. We need to select the project file to import, and then click "Browse ..." to find the project file TestAll.

5. Finally, check Copy Project to Workspace and click Finish to complete the project import.

6. At this point, the TestAll file has been imported into eclipse.
