Using Maven 2 in NetBeans 4.0 (4.1 and 5.0)

This mini guide explain by examples how to use Maven 2 in NetBeans IDE.

To use Maven 2 in NetBeans you have to follow these steps:

Retrieve/Create the Maven 2 project

This guide assume the project is created using the archetype plugin. You can also checkout the Maven 2 project using your versionning system.

Launch Maven 2 in command line using the netbeans-freeform plugin

After having retrieved the Maven 2 project, you have to enable the project to be seen as a NetBeans 4.0, 4.1 or 5.0 project using the NetBeans Freeform project type.

To enable the project, use the netbeans-freeform plugin for Maven 2.

[maven-user@mini-guide demoquickstart]$ mvn netbeans-freeform:generate-netbeans-project
[INFO] Searching repository for plugin with prefix: 'netbeans-freeform'.

The netbeans-freeform plugin creates one directory and three files by reading the Maven 2 project descriptor:

  • The nbproject directory holds the NetBeans project descriptor.
  • The <project.xml file is the NetBeans Freeform project descriptor.
  • The mavencall.xml holds the Ant calls which execute Maven 2, as NetBeans uses Ant as its build tool.
  • The files holds the two properties: local.repository which is the absolute path to the Maven 2 local repository and which is the absolute path to the project directory.

Open the project with NetBeans

Now that the Maven 2 project is eneabled for use in NetBeans, open your NetBeans IDE. Then open the project (Ctrl+Maj+O).

Here is the Open Project window.

Open Project

And here are:

The Projects Window with the opened project.

Project Opened

The project's Context Menu of the opened project.

And the Files Window with the opened project.

Files Window

Build the project and launch other Maven goals

It is now time to try the first execution of Maven 2 from within NetBeans. Try the Build Main Project NetBeans action (F11). You see the Maven 2 execution of the package lifecycle goal.

Run Build Main Project

You can also call the Clean Project NetBeans action which is mapped to the clean Maven2 goal.

Run Clean Main Project

Edit properties of the plugin

Now you can add some additionnal views in your Projects window in NetBeans. Like an additionnal goal in the context menu.

<project xmlns="" 
  <name>Maven Quick Start Archetype</name>

You can also configure some additionnal files and folders in the Projects window.

The last option is to create the nbproject folder and its content in another directory than in the Maven 2 project's one.

The full configuration can be found at

Refresh the project view

To refresh the Project view in NetBeans accordingly to the new configuration added to the Maven 2 project descriptor. Just right-clic the project in the Projects window and choose the Refresh Project action.

Refresh Project

Here is the resulting refreshed Context Menu.

Refreshed Context Menu

Build the Maven 2 site

You can call The Generate Javadoc for Project NetBeans action which is mapped to the site Maven 2 goal, here in the Maven site archetype.
