How to programmatically call a Maven-task

Question

I\'m using Maven in the context of another build-tool (leiningen for Clojure, but this should not matter), and I would like to know how I would call a plugin like dependency:bui

Answer 1

Use the Maven Invoker API. Its quick and easy.

InvocationRequest request = new DefaultInvocationRequest();
request.setPomFile( new File( "/path/to/pom.xml" ) );
request.setGoals( Collections.singletonList( "install" ) );

Invoker invoker = new DefaultInvoker();
invoker.setMavenHome(new File("/usr"));

try
{
  invoker.execute( request );
}
catch (MavenInvocationException e)
{
  e.printStackTrace();
}

pom.xml:

    org.apache.maven.shared
    maven-invoker
    2.1.1
