mvn install usage

The mvn install command is used in Apache Maven to compile, test, package, and install a project into the local repository (~/.m2/repository). This makes the built artifact available for use as a dependency in other projects.

Usage

mvn install

mvn clean install

What It Does

1. Compiles the Code (mvn compile): Compiles the Java source files.
2. Runs Tests (mvn test): Executes unit tests.
3. Packages the Artifact (mvn package): Creates a JAR or WAR file.
4. Installs the Artifact (mvn install): Copies the built artifact (e.g., JAR, WAR, POM) to the local Maven repository.

Common Options

• -DskipTests: Skips running tests.

  mvn install -DskipTests

• -T 4 or -T 1C: Runs the build in parallel (e.g., using 4 threads or 1 per CPU core).

  mvn install -T 4

• -U: Forces an update of dependencies from remote repositories.

  mvn install -U

• -Dmaven.javadoc.skip=true: Skips Javadoc generation.

  mvn install -Dmaven.javadoc.skip=true

When to Use mvn install

• To install your project into the local repository for use in other projects.
• Before deploying the artifact to a remote repository (mvn deploy).
• To verify that the project is buildable and can be used as a dependency.
