Svn:is already under version control error resolution

Sometimes we copy a folder from another project to the current project for ease of operation, and the following error occurs when submitting the folder to the SVN server:

SVN: ' E:\MyEclipse\workspace\honsto-cms\WEB-INF\jsp\back\mcCommonData ' is already under version control

(The Red Font section is the problem folder address, depending on the reader's own situation).

Reason: This error occurs because of the management information (. SVN folder) that was sandwiched in the previous SVN server when we copied the folder into the current project.

To copy in and conflict with the current SVN server.

Workaround: Locate the folder in the Delete subdirectory in the computer. The SVN folder can be submitted correctly when the item is refreshed.
