However, if you browse the plugin's documentation site and look for the properties that can be used to configure the compile goal you'll notice there are two properties that control the source (maven.compiler.source) and target (maven.compiler.target) values. The Compiler Plugin can also be configured to provide these options during compilation. We've reached the fifth stop of the Mastering Maven series, concluding with the basics.
