Eclipse version restore

[team]-[Show Resource History], under [History] of eclipse, select a row, right-click, if you select [Respond to Modifications from Modified Version 121], multiple different versions will be listed. If you choose [Switch to Revision 10583], it will return to 10583, but it does not mean that the entire project has returned to 10583. If no modification is made, it will continue to become the latest version after the update.
