Using myeclipse development, the code needs to be submitted to the SVN server, so the SVN plug-in is installed. When trying to share the project to the SVN server, the message "The project already has an SVN/ directory, it is possible that it has been shared before... " causes the project to not be shared.
Analysis of the reason: Since the current project has been associated with the SVN server, the server is connected to the "SVN Repositories" of the development tool, and the local project has information related to SVN.
Solution:
Go to the project directory and release the hidden folder ( .svn )
After deleting the ".svn" folder, refresh the project, and then share the project to the new SVN server.
