wro4j is a project that will help you to easily improve your Web application page loading time. It can help you to keep your static resources (JavaScript and CSS) well organized, merge and minify them at run-time (using a simple filter) or build-time (using a Maven plugin), and has several features you may find useful when dealing with Web resources.


One of the most important features of this release is jsLint support (previously, only jsHint was supported). It also contains fixes for a number of bugs and other small improvements.
