When developing a project in a team, it is necessary to apply version control. The CVS function in eclipse can be used for version control. When team members need to complete the project module, they should connect to the cvs server and download the latest version of the project from the server for development and coding. After the commit is completed, the other team members can also modify it accordingly and avoid conflicts.
To cancel cvs, you can right-click on the project -> properties -> group -> disconnect -> delete the cvs information at the same time, in this case, all the cvs information including folders are automatically deleted.
