unreal engine c++ function already has a body

The most likely cause is you have included ".cpp" file in one of your other files.

        b-go to "c:/SVN" and hold shift and right click to open power shell or command line

        c-type in this command line 

        svnadmin create --compatible-version 1.9 --fs-type fsfs MyNewRepository        

    Note: you will get this error if you don't do this step

SourceControl: Error: svn: E180001: Unable to open repository ''
Source Control: Error: svn: E160043: Expected FS format between '1' and '7'; found format '8'
SourceControl: Error: Failed to connect to source control. Check your settings and connection then try again.

4- go to your Project folder  and right click then select SVN checkout...
