title: Jenkins SubWCRev E155036 working copy is too old
body: <p>im getting an error during the build process on our Jenkins Server, since i tried to use the Tortoise SubWCRev.exe in a prebuild Event to get the Revision number and place it in the assembly file. </p>
  
  <p>This is the Error:</p>
  
  <blockquote>
    <p>PreBuildEvent:
      SubWCRev.exe "...\Jenkins\jobs... " "...\Jenkins\jobs...\Properties\AssemblyInfo.cs.template " "...\Jenkins\jobs...\Properties\AssemblyInfo.cs "</p>
    
    <p>SubWCRev : E155036: The working copy at '...\Jenkins\jobs...\workspace\code'
      is too old (format 29) to work with client version '1.8.10 (r1615264)' (expects format 31). You need to upgrade the working copy first.</p>
  </blockquote>
  
  <p>When i do a Rebuild on my local machine it works fine and replaces the Revisionumber in the AssemblyInfo.cs File.</p>
  
  <p>I am pretty new to Subversioning and Jenkins, so i dont have a clue at the moment.</p>
