Expose node task's execResult

[ljohnston]

The node task should expose it's execResult as the Gradle Exec task does.

Use case: I want to ignore the exit value of some of my node-based test tasks (i.e. ignoreExitValue = true), but retrieve their actual success/failure status via execResult.exitValue.

Thanks,
Lance

+1 - I'm just looking at this now, because I want to redirect the output/error streams to something that isn't the console but then on an error condition, print out the entire output so it's not interleaved with the output from other tasks.

Will pull in your pull request i a couple of hours. Thanks.

@johnrengelman Can you share how you were able to redirect output/error streams?

I'm trying to do the same thing, but standardOutput and errorOutput are not exposed on the Node/Npm Tasks (which wrap and insulate an internal Exec runner) so not sure how to do this. My thought was:

standardOutput = new ByteArrayOutputStream()
    errorOutput = standardOutput
    ignoreExitValue = true
    doLast {
        if (result.exitValue != 0) {
            println(standardOutput.toString())
            throw new GradleException("exec failed; see output above")
        }
    }

But standardOutput as I mentioned isn't defined on NodeTask or NpmTask.

I was able to get something to work, although I'm not sure it's the best strategy. If either of you have better suggestion, would appreciate it.

ignoreExitValue = true
    def execRunner = null
    execOverrides {
        execRunner = it
        it.standardOutput = new ByteArrayOutputStream()
        it.errorOutput = it.standardOutput
    }
    doLast {
        if (result.exitValue != 0) {
            println(execRunner.standardOutput.toString())
            throw new GradleException("exec failed; see output above")
        }
    }
