Common Maven Commands Explained (Including for Eclipse IDE)

Maven is a powerful build automation tool for Java projects. Whether you're using Maven via the command line or integrated with Eclipse IDE, the core commands remain the same. Here's a breakdown:

Common Maven Commands (Command Line & Eclipse IDE)

Command	Description
mvn clean	Deletes the target/ directory. Ensures a clean build.
mvn compile	Compiles the Java source code in the src/main/java directory.
mvn test	Runs unit tests in src/test/java.
mvn package	Packages compiled code into a .jar or .war file.
mvn install	Installs the .jar or .war to your local Maven repository (~/.m2).
mvn deploy	Deploys the artifact to a remote repository (e.g., Nexus, Artifactory).
mvn site	Generates project documentation (using plugins).
mvn validate	Validates the project structure and checks for missing info in pom.xml.
mvn verify	Runs additional checks like integration tests.

mvn archetype:generate	Creates a new Maven project from an archetype (template).

Using Maven Commands in Eclipse IDE

Eclipse IDE (with M2E Plugin—Maven integration) allows you to run Maven commands without using the terminal.

To Run Maven Goals in Eclipse:

1. Right-click on your Maven project in Project Explorer.

2. Choose Run As > Maven build...

3. In the Goals field, enter one or more of the following:

   • clean

   • compile

   • package

   • install

   • test

   • site

4. Click Run.

After adding dependency in pom.xml, we should update project, as shown below:

• Right-click → Maven → Update Project to refresh dependencies.

We can also execute maven commands from command line from project workspace.

go to project workspace and open cmd terminal and execute below command:
mvn clean install
