      (slave) Windows Server 2012 x64
      Oracle JDK 1.7.1_71

      Using the workflow-plugin the 'sh' task hangs after an 'env' task call, even when the 'env' is on a different node. Here's a real example that hangs on the 'sh' call:

      node('windows-doc') {
    echo "On my Windows slave"
    env.PATH = "C:\\Program Files (x86)\\MadCap Software\\MadCap Flare V10\\Flare.app;%PATH%"
}

node('master') {
    echo "On master"
    sh "ls -l"
}

      Remove the 'env.PATH' from that, and it will not hang.

          This is a user error which is not reported gracefully, as noted in JENKINS-26105. env is global to the flow build, not block-scoped (see JENKINS-26128), so by the time the sh step is run it is given a $PATH which does not include /bin and thus the sh executable is not found.

          For this reason the Workflow tutorial does not advocate using env for anything machine-specific (like file paths) if you are using multiple nodes. Use fully-qualified executable names instead.

          Great, thank you. I didn't pick that up in the tutorial. That is the exact workaround I found. Thanks!
