11.19. Maven NetBeans

Maven has been built into NetBeans 6.7 and later. For previous versions, the Maven plug-in is available in the plug-in Administration Center. In this example, we are using NetBeans 6.9. Some features about NetBeans are as follows:

You can run the Maven target through NetBeans.
You can view the output of the Maven command using NetBeans’s own console.
Maven and IDE dependencies can be updated.
You can start the build of Maven in NetBeans.
NetBeans is based on Maven’s pom.xml to automate dependency management.
NetBeans can solve the Maven dependency problem through its own workspace without having to install to the local Maven repository, although the dependent project is in the same workspace.
NetBeans can automatically download the required dependencies and source code from the remote Moven library.
NetBeans provides wizards to create Maven projects and pom.xml files.
NetBeans provides browsers for Maven repositories that allow you to view local repositories and Maven repositories registered externally.

11.19.1. Open a Maven project in NetBeans ¶

Open NetBeans
Choice File Menu > Open Project Option
Select the path to the project, that is, the storage path when you create a project using Maven. Suppose we create a project: consumerBanking. Pass through Maven 构建 Java 项目 See how to create a project using Maven.

So far, you can see the Maven project in NetBeans. Take a look at Libraries and Test Libraries of the consumerBanking project. You can see that NetBeans has added everything that Maven depends on to its build path.

11.19.2. Build a Maven project in NetBeans ¶

All right, let’s use NetBeans’s compilation function to build this Maven project.

Right-click the consumerBanking project to open the context menu.
Select the “Clean and Build” option

Maven will start building the project. You can view the output log information in the NetBeans terminal:
