title: are there any examples of how to use maven-jar-plugin?
body: <p>I am very new to Maven and would like to see an example of how one uses the maven jar plugin. I already visited <a href="http://maven.apache.org/plugins/maven-jar-plugin/jar-mojo.html" rel="noreferrer">here</a> but did not find any examples. On the documentation page, there were some parameters listed for this goal but what I was looking for is how one places them in the 'goal' or 'executions' tag. Thanks.</p>
