gradle Exec block should not fail for non zero output in

Question

I am writing a gradle task. The task it invokes returns 3 for successful run instead of 3. How do I go about doing this ?

task copyToBuildShare(){
   def robocopySourceDir = "build\\outputs\\apk"
   def cmd = "robocopy "+ robocopySourceDir + " C:\\TEST *.* /MIR /R:5 2>&1"
   exec {
      ignoreExitValue = true
      workingDir '.'
      commandLine "cmd", "/c", cmd
      if (execResult.exitValue == 3) {
         println("It probably succeeded")
      }
   }
}

It gives the error:

Could not find property 'execResult' on task

I don't want to create a separate task. I want it to be in the exec block. What am I doing wrong?

You're going to need to specify that this task is of type Exec. This is done by specifying the task type like so

task testExec(type: Exec) {

}

In your specific case, You'll also want to make sure you don't try to get the execResult until the exec has finished this can be done by wrapping the check in a doLast.

task testExec(type: Exec) {
    doLast {
        if (execResult.exitValue == 3) {
            println("It probably succeeded")

        }
    }
}

Here's an example of executing ls and checking its return value

task printDirectoryContents(type: Exec) {

    workingDir '.'
    commandLine "sh", "-c", "ls"

    doLast{
        if (execResult.exitValue == 0) {
            println("It probably succeeded")

        }
    }
}
