We have updated our Jenkins instances to 2.204.5 LTS, but the problem is still there.

• docker-commons:1.16
• docker-workflow:1.23
• pipeline-build-step:2.11

Same problem for us, we have implemented a small wrapper around sh/bat commands, and devs see a lot of uneeded 'isUnix' steps.

def call(cmd) {
  if (isUnix()) {
    sh cmd
  } else {
    // If we use "returnStdout", need to remove command itself from stdout to work like 'sh' command
    if (cmd instanceof Map && cmd.returnStdout) {
      cmd.script = '@' + cmd.script
    }
    bat cmd
  }
}

If some steps can me marked as "invisible" (steps without side effects maybe ?) this could be great.

to mee it seems by some magic the "isUnixStep" (Step) is launched, as that seems to provide exactly this message:
https://github.com/jenkinsci/workflow-basic-steps-plugin/blob/master/src/main/java/org/jenkinsci/plugins/workflow/steps/IsUnixStep.java

In general it seems the "isUnix" is some API-Implementation as part of the Launcher:
https://github.com/jenkinsci/jenkins/blob/master/core/src/main/java/hudson/Launcher.java

I think it boils down to the fact that the docker-workflow-plugin (providing the docker.xyz steps) is using the isUnix Step implementation of the node, and not the isUnix API of the launcher in shell() method like here: https://github.com/jenkinsci/docker-workflow-plugin/blob/master/src/main/resources/org/jenkinsci/plugins/docker/workflow/Docker.groovy

now, can we do anything here?

Could the ticket be assigned to the main commiter of the docker-workflow-plugin since Peter Niederlag seems to have found the problem?

+1 this is such a noisy useless log message.

Vincent Latombe is there any chance you can tackle this? Big thx for any feedback
