Issue: When synchronizing a project, the Classes folder is added to the synchronous version due to misoperation, which causes many class files to appear in the synchronization manifest after each update compilation.
Solution: Do not set the classes file to synchronize.
1. The default classes folder is hidden in Eclipse and how the classes folder is displayed in Eclipse.
Project Explorer, triangle (view Menu)->customize view. Then remove the Java output folders in the right-hand image.
2. How to set the Classes folder out of sync
Right-click to delete the folder directly. After deletion, it becomes the shape with the fork icon on the right.
This time to submit this synchronization information to the server, after the synchronization is complete, the corresponding folder on the server classes also deleted.
At this point, the local folder does not have a sync tag or a fork icon. At this point, set the folder to be hidden, and avoid syncing again next time.
