# EMB - Extensible, Modular Builds #

EMB is a build tool that wraps and extends [Apache Maven](http://maven.apache.org/). Its goal is to provide a mechanism for changing the core functionality of Maven using sets of add-on libraries.

## Getting Started ##

The simplest way to use EMB is via the emb-booter. To do this, first add a dependency in your POM to emb-booter:

    

      4.0.0

      org.commonjava.emb.example

      example

      1.0-SNAPSHOT

      

        3.0-beta-2

        0.3-SNAPSHOT

      

      

        

          org.commonjava.emb

          emb-booter

          ${embVersion}

        

      

    

Then, create a new EMBEmbedder instance, and use it to build a project:

    List goals = new ArrayList();

    goals.add( "clean" );

    goals.add( "install" );

    new EMBEmbedderBuilder().build().execute( new EMBExecutionRequest().setGoals( goals ) );

  

## Using Services ##

You can use allowed Maven components via the ServiceManager. For instance, to resolve an artifact:

    EMBEmbeder emb = new EMBEmbedderBuilder().build();

    emb.serviceManager().repositorySystem().resolve( artifact );

  

Or, to build a set of MavenProject instances from POM files:

    EMBEmbeder emb = new EMBEmbedderBuilder().build();

    

    ProjectBuildingRequest req = new DefaultProjectBuildingRequest()

                                      .setSystemProperties( System.getProperties() )

                                      .setValidationLevel( ModelBuildingRequest.VALIDATION_LEVEL_MINIMAL )

                                      .setForceUpdate( true )

                                      .setProcessPlugins( false )

                                      .setRepositoryCache( new InternalRepositoryCache() )

                                      .setLocalRepository( emb.serviceManager()

                                                              .repositorySystem()

                                                              .createLocalRepository( new File( workDir, "local-repository" ) ) );

                             

    List results = emb.serviceManager().projectBuilder().build( pomFiles, useReactor, req );

    

    List projects = new ArrayList( pomFiles.size() );

    for ( final ProjectBuildingResult result : results )

    {

        projects.add( result.getProject() );

    }
