Stopping a Windows service that isn’t running causes build to fail

Using the following Gradle action,

developerBuild << {
   exec {
      commandLine = ['cmd', '/c', 'net', 'stop', 'Foo']
   }
}

If I execute this task and the Windows service Foo isn’t running, I’ll get the following exception,

The Foo service is not started.

More help is available by typing NET HELPMSG 3521.

FAILURE: Build failed with an exception.

* Where:
Build file 'C:...build.gradle' line: ..

* What went wrong:
Execution failed for task ':developerBuild'.
> Command 'cmd' finished with (non-zero) exit value 2.

* Try:
Run with --info or --debug option to get more log output.

* Exception is:

BUILD FAILED

This will cause the execution of the entire task to stop, why? Is there a way to continue with the task regardless of the exit code of the command line call in an action?

Answer

You can disable the exit value check on an ExecSpec as follows:

developerBuild << {
  exec{
    commandLine = ['cmd', '/c', 'net', 'stop', 'Foo']
    ignoreExitValue = true
  }
}
