IntelliJ IDEA has in-built support for Maven. We are using IntelliJ IDEA Community Edition 11.1 in this example.

Some of the features of IntelliJ IDEA are listed below −

  • You can run Maven goals from IntelliJ IDEA.

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

  • You can update maven dependencies within IDE.

  • You can Launch Maven builds from within IntelliJ IDEA.

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

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

  • IntelliJ IDEA automatically downloads the required dependencies and sources from the remote Maven repositories.

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

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