+# simple-java-maven-app
+
+This repository is for the
+[Build a Java app with Maven](https://jenkins.io/doc/tutorials/build-a-java-app-with-maven/)
+tutorial in the [Jenkins User Documentation](https://jenkins.io/doc/).
+
+The repository contains a simple Java application which outputs the string
+"Hello world!" and is accompanied by a couple of unit tests to check that the
+main application works as expected. The results of these tests are saved to a
+JUnit XML report.
+
+The `jenkins` directory contains an example of the `Jenkinsfile` (i.e. Pipeline)
+you'll be creating yourself during the tutorial and the `scripts` subdirectory
+contains a shell script with commands that are executed when Jenkins processes
+the "Deliver" stage of your Pipeline.
