I'm checking out the PREBUILD and POSTBUILD option in a DSC.  I can launch my scripts, etc.

When there is a POSTBUILD error,  build.py properly says the build failed, but build.py is still returning 0 (success).  MyBuild.LaunchPostBuild() execution does not look like it affects ReturnCode which is returned at the end of Main.  "Conclusion" is updated though to indicate a failure.  Any ideas?  I assume build.py should return non-zero if POSTBUILD fails.

From end of edk-stable202011build.py:Main()

    if ReturnCode == 0:

        try:

            MyBuild.LaunchPostbuild()

            Conclusion = "Done"

        except:

            Conclusion = "Failed"

    elif ReturnCode == ABORT_ERROR:

        Conclusion = "Aborted"

    else:

        Conclusion = "Failed"

    FinishTime = time.time()

    BuildDuration = time.gmtime(int(round(FinishTime - StartTime)))

    BuildDurationStr = ""

    if BuildDuration.tm_yday > 1:

        BuildDurationStr = time.strftime("%H:%M:%S", BuildDuration) + ", %d day(s)" % (BuildDuration.tm_yday - 1)

    else:

        BuildDurationStr = time.strftime("%H:%M:%S", BuildDuration)

    if MyBuild is not None:

        if not BuildError:

            MyBuild.BuildReport.GenerateReport(BuildDurationStr, LogBuildTime(MyBuild.AutoGenTime), LogBuildTime(MyBuild.MakeTime), LogBuildTime(MyBuild.GenFdsTime))

    EdkLogger.SetLevel(EdkLogger.QUIET)

    EdkLogger.quiet("\n- %s -" % Conclusion)

    EdkLogger.quiet(time.strftime("Build end time: %H:%M:%S, %b.%d %Y", time.localtime()))

    EdkLogger.quiet("Build total time: %s\n" % BuildDurationStr)

    Log_Agent.kill()

    Log_Agent.join()

    return ReturnCode
