Eclipse won't update after adding project to workspace folder

Question

I added a Java project (containing one default package with 2 classes) to my folder which I declare as my workspace in Eclipse. But when I launch Eclipse, it does not add this project in the package explorer. What can I do to solve this problem?

Answer 1

You can't copy files or folders to your workspace folder, you have to import the project into Eclipse:

1. From the main menu bar, select command link File > Import.... The Import wizard opens.
2. Select General > Existing Project into Workspace and click Next .
3. Choose either Select root directory or Select archive file and click the associated Browse to locate the directory or file containing the projects.
4. Under Projects select the project or projects which you would like to import.
5. Click Finish to start the import.
