Stages, Steps, and Post Blocks

Part of the Jenkins course

Your first pipeline was one sh line, and it worked. A real one is a checkout, a build, a test and a package, and the moment you have four of those in a row you hit a new problem: something failed, and the console log is nine hundred lines of shell output with no signposts in it. Worse, when the test step fails the pipeline stops dead, so the test report that would have told you which test failed never gets published.

This lesson fixes both. Stages give the pipeline visible structure, and post blocks give it a guaranteed ending that runs whether the middle succeeded or not. ...
