  Imho it is the same problem as
  
  	
  JENKINS-68035
  	
  JENKINS-67240
  
  
  
  The error triggers in the same point of code (off by a line because of the version change).
  
   
  
  Maybe is related to some config update.
  
   
  
  I was migrating my jenkins from one computer (Windows 8) to another (Windows 10) and the pipeline stop working.
  
   
  
  I changed the PATH variable, replicate the plugin list in the two computers and many other tries without luck.

  I experienced the same issue.
  
  For me the problem was caused by more than one ssh-agent.exe in PATH environment variable.
  
  I moved the PATH for ssh-agent.exe used by git.exe to the front, and the problem was solved for me.

  Thanks a lot shin_t, this clearly put us in the right direction to troubleshoot our issue.
  
  We are adding git ssh-agent in Windows agent path using Jenkins Node properties: PATH+GITSSH=...
  
  Turns out such property is not yet computed during the ssh-agent build-wrapper step (at least in our case of FreeStyle job).
  So plugin was trying to use Windows OpenSSH ssh-agent, which is known not to work properly
  
  Solution is to put git ssh-agent in Windows agent path at OS level (*system *environment variables), so the correct version is picked-up and used by Jenkins plugin.
