Maven in NetBeans
NetBeans 6.7 and newer versions have Maven built-in. For earlier versions, you can obtain the Maven plugin from the Plugin Manager. In this example, we are using NetBeans 6.9. Some features of NetBeans include:
- You can run Maven goals through NetBeans.
- You can view the output of Maven commands using NetBeans' own console.
- You can update dependencies between Maven and the IDE.
- You can initiate Maven builds within NetBeans.
- NetBeans manages dependencies automatically based on Maven's pom.xml.
- NetBeans can resolve Maven dependencies through its workspace without needing to install them in the local Maven repository, although the dependent projects need to be in the same workspace.
- NetBeans can automatically download required dependencies and sources from remote Maven repositories.
- NetBeans provides wizards for creating Maven projects and pom.xml files.
- NetBeans offers a Maven repository browser, allowing you to view both local repositories and externally registered Maven repositories.
Opening a Maven Project in NetBeans
- Open NetBeans
- Select File Menu > Open Project
- Choose the project path, which is the storage path when you create a project using Maven. Let's say we've created a project: consumerBanking. Refer to Creating a Java Project with Maven for how to create a project using Maven.
So far, you should be able to see the Maven project in NetBeans. Take a look at the Libraries and Test Libraries of the consumerBanking project. You'll notice that NetBeans has added all Maven dependencies to its build path.
Building a Maven Project in NetBeans
Now, let's use NetBeans' compile function to build the Maven project.
- Right-click the consumerBanking project to open the context menu.
- Select "Clean and Build"
Maven will start building the project. You can view the log output in NetBeans' terminal:
NetBeans: Executing 'mvn.bat -Dnetbeans.execution=true clean install'
NetBeans: JAVA_HOME=C:\Program Files\Java\jdk1.6.0_21

### Running the Application in NetBeans
Now, right-click the App.java file. Select the Run File option. You can see the following result in the terminal:
NetBeans: Executing 'mvn.bat -Dexec.classpathScope=runtime -Dexec.args=-classpath %classpath com.companyname.bank.App -Dexec.executable=C:\Program Files\Java\jdk1.6.0_21\bin\java.exe -Dnetbeans.execution=true process-classes org.codehaus.mojo:exec-maven-plugin:1.1.1:exec' NetBeans: JAVA_HOME=C:\Program Files\Java\jdk1.6.0_21
