NetBeans 6.7 and newer has in-built support for Maven. In case of previous version, Maven plugin is available in plugin Manager. We are using NetBeans 6.9 in this example.

Some of features of NetBeans are listed below −

  • You can run Maven goals from NetBeans.

  • You can view the output of Maven commands inside the NetBeans using its own console.

  • You can update maven dependencies with IDE.

  • You can Launch Maven builds from within NetBeans.

  • NetBeans does the dependency management automatically based on Maven's pom.xml.

  • NetBeans resolves Maven dependencies from its workspace without installing to local Maven repository (requires dependency project be in same workspace).

  • NetBeans automatic downloads required dependencies and sources from the remote Maven repositories.

  • NetBeans provides wizards for creating new Maven projects, pom.xml.

  • NetBeans provides a Maven Repository browser that enables you to view your local repository and registered external Maven repositories.

Following example will help you to leverage benefits of integrating NetBeans and Maven.
