Calling Maven goals from Java

Question

Is it possible to call Maven goals from Java, for instance, can I do the equivalent of:

mvn clean package

from a Java class?

thanks, Nick

Answer 1

absolutely, you need to use the Maven Embedder API.

Answer 2

This is easy :)

Java code

MavenCli cli = new MavenCli();
cli.doMain(new String[]{"clean", "package"}, "project_dir", System.out, System.out);

Project configuration:

<dependencies>
    <dependency>
        <groupId>org.apache.maven</groupId>
        <artifactId>maven-embedder</artifactId>
        <version>3.1.1</version>
    </dependency>
    <dependency>
        <groupId>org.eclipse.aether</groupId>
        <artifactId>aether-connector-wagon</artifactId>
        <version>0.9.0.M2</version>
    </dependency>
    <dependency>
        <groupId>org.apache.maven.wagon</groupId>
        <artifactId>wagon-http-lightweight</artifactId>
        <version>2.5</version>
    </dependency>
</dependencies>
