+ AbstractProcessStep is a convenience class, which can be used as a base class instead of BuildStep.
+ It should be used as a base class if your buildstep just needs to run a process.
+
+ Usage:
+ Use setCommand(), setArguments(), setWorkingDirectory() to specify the process you want to run.
+ (You need to do that before calling AbstractProcess::init())
+ Inside YourBuildStep::init() call AbstractProcessStep::init()
+ Inside YourBuildStep::run() call AbstractProcessStep::run(), which automatically starts the proces
+ and by default adds the output on stdOut and stdErr to the OutputWindow.
+ If you need to process the process output override stdOut() and/or stdErr.
+ The two functions processStarted() and processFinished() are called after starting/finishing the process.
+ By default they add a message to the output window.
+
+ Use setEnabled() to control wheter the BuildStep needs to run. (A disabled BuildStep immediately returns true,
+ from the run function.)
