Quick tip: Passing parameters from Jenkins to Maven

I saw bits and pieces of information all over the internet about parameters and properties and command-line arguments, but what I was looking for I didn’t find: a simple, straightforward explanation of how to use a Paramaterized Build in Jenkins to pass arguments through to the jUnit tests that run the functional tests that I’ve built on Webdriver. So: here it is!
Step 1: Command-line via Maven to jUnit
Use the System.getProperty tor ead system properties in Java:
　　remoteHost = System.getProperty("remoteHost");
　　if (remoteHost == null) remoteHost = "http://localhost:4444/wd/hub";
　　browserName = System.getProperty("browserName");
　　if (browserName == null) browserName = "Internet Explorer";
And use -D to pass them with Maven:
　　mvn test -DbrowserName=Firefox

Step 2: Jenkins to Maven
First make the build a paramaterized build:

Then adjust the maven build step as shown:
