Class MojoExecutor

java.lang.Object

org.twdata.maven.mojoexecutor.MojoExecutor

public class MojoExecutor
extends Object

Executes an arbitrary mojo using a fluent interface. This is meant to be executed within the context of a Maven 2 mojo.

Here is an execution that invokes the dependency plugin:

 executeMojo(
              plugin(
                      groupId("org.apache.maven.plugins"),
                      artifactId("maven-dependency-plugin"),
                      version("2.0")
              ),
              goal("copy-dependencies"),
              configuration(
                      element(name("outputDirectory"), "${project.build.directory}/foo")
              ),
              executionEnvironment(
                      project,
                      session,
                      pluginManager
              )
          );
