You need to use Commons CLI (Command-Line Interface) to parse an application's command-line arguments.

To use Commons CLI 1.1 in a Maven 2 project, add the following dependency to your project's pom.xml:

<dependency>
    	<groupId>commons-cli</groupId>
    	<artifactId>commons-cli</artifactId>
    	<version>1.1</version>
    </dependency>

If you are not sure what this means, I'd suggest reading Maven: The Definitive Guide. When you depend on a library in Maven 2, all you need to do is add the dependency groupId, artifactId, and version to your project's dependencies. Once you do this, Maven 2 will download the dependency and make it available on your project's classpath.

For more information about the Commons CLI project, see the Commons CLI project page at http://commons.apache.org/cli.
