We updated to Jenkins LTS 2.401.1 via dockerhub. Since that version all our pipeline builds broke because the bat pipeline step seems to also return the command call itself in the result which it did not before. Powershell works.

See the following code to reproduce the problem

stage('Test') {
  steps {
    script {
      def result = bat(label: '', returnStdout: true, script: 'echo echotestresponse')
      echo "output from bat: $result"
      def psResult = powershell(label: '', returnStdout: true, script: 'echo echotestresponse')
      echo "output from powershell: $psResult"
    }
  }
}

Output is:

17:17:18  [Pipeline] stage
17:17:18  [Pipeline] { (Test)
17:17:18  [Pipeline] script
17:17:18  [Pipeline] {
17:17:18  [Pipeline] bat
17:17:18  [Pipeline] echo
17:17:18  output from bat: 
17:17:18  jenkins@HMJENKINS4 d:\jenkins\workspace\MPA_jenkins-fixing>echo echotestresponse 
17:17:18  echotestresponse
17:17:18  
17:17:18  [Pipeline] powershell
17:17:19  [Pipeline] echo
17:17:19  output from powershell: echotestresponse
17:17:19  
17:17:19  [Pipeline] }
17:17:19  [Pipeline] // script
17:17:19  [Pipeline] }
17:17:19  [Pipeline] // stage

Additionally there is also a new line character at start of the result now.

A workaround seems to be to prefix any command with @ or @echo off explicitely.

Description

Original: We updated to Jenkins LTS 2.401.1 via dockerhub. Since that version the bat pipeline step seems to be broken and does not return stdout anymore. The same code with powershell works.

See the following code to reproduce the problem
{code:java}
stage('Test') {
  steps {
    script {
      def result = bat(label: '', returnStdout: true, script: 'echo echotest response')
      echo "output from bat: $result"

      def psResult = powershell(label: '', returnStdout: true, script: 'echo echotest response')
      echo "output from powershell: $psResult"
    }
  }
} {code}
Output is:

{code:java}
16:56:23 [Pipeline] stage
16:56:23 [Pipeline] { (Test)
16:56:23 [Pipeline] script
16:56:23 [Pipeline] {
16:56:23 [Pipeline] bat
16:56:23 [Pipeline] echo
16:56:23 output from bat:
16:56:23 jenkins@HMJENKINS4 d:\jenkins\workspace\MPA_jenkins-fixing>echo echotest response
16:56:23 echotest response
16:56:23
16:56:23 [Pipeline] powershell
16:56:24 [Pipeline] echo
16:56:24 output from powershell: echotest
16:56:24 response
16:56:24
16:56:24 [Pipeline] }
16:56:24 [Pipeline] // script
16:56:24 [Pipeline] }
16:56:24 [Pipeline] // stage
{code}

Variable is not set with output from stdout in bat step. See "output from bat:"
