Issue

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

Environment

• Jenkins
• CloudBees Jenkins Enterprise
• Pipeline plugin
• Windows node/agent

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.
