Issue

The bat directive in Pipeline returns cmd is not recognized as an internal or external command, operable program or batch file.

Environment

• CloudBees Core on modern cloud platforms - Managed Master

• CloudBees Core on traditional platforms - Client Master

• CloudBees Jenkins Enterprise - Managed Master

• CloudBees Jenkins Platform - Client Master

• CloudBees Jenkins Distribution

• Jenkins LTS

• Pipeline running on a Windows environment

Resolution

• You need to make sure the user running the Jenkins Master/Slave where the command is executing has C:\Windows\System32 in it’s PATH variable.
• To add this to that user’s PATH, right click on My Computer then select Properties. Click Advanced then click Environment Variables.
  Scroll down to PATH and add C:\Windows\System32 to it.
• If the PATH is properly set but the error still appears, include the PATH through a environment variable. This is a known bug managed in https://issues.jenkins-ci.org/browse/JENKINS-44334.

   environment {
       env.PATH = env.PATH + ";c:\\Windows\\System32"
   }
