The Maven JSTools Plugin is, well, a javascript plugin for Maven 2. More specifically, it provides a Maven2 interface to a set of JavaScript development tools like JSDoc and JSLint, along with runtime JS dependency resolution (well it sounds cool) tools for your WAR projects. Support for JSUnit/ECMAUnit is coming up!
