  Getting to Plexus-configured Mojos

Abstract

  We're moving toward integrating mojos as first-class plexus components, while
  at the same time avoiding introducing required plexus dependencies into the
  mojo development model.

    private List<LifecycleMojo> mojos;

    public LifecyclePhase() {}

    public LifecyclePhase(String goals) {
        set(goals);
    }

    public List<LifecycleMojo> getMojos() {
        return mojos;
    }

    public void setMojos(List<LifecycleMojo> mojos) {
        this.mojos = mojos;
    }

    public void set(String goals) {
        mojos = new ArrayList<>();

        InputLocation location = DefaultLifecycleRegistry.DEFAULT_LIFECYCLE_INPUT_LOCATION;

        List<LifecycleMojo> mojos = goals.getMojos();
        if (mojos != null) {
            for (int i = 0; i < mojos.size(); i++) {
                LifecycleMojo mojo = mojos.get(i);

                // Compute goal coordinates
                String groupId, artifactId, version, goal;

        // which uses role:roleHint for identity...and roleHint == goalPrefix:goal.
        // role does not vary for Mojos.
        List<MojoDescriptor> mojos = getMojos();

        if (mojos != null && mojos.contains(mojoDescriptor)) {
            int indexOf = mojos.indexOf(mojoDescriptor);

            existing = mojos.get(indexOf);
        }

        if (existing != null) {

        InputLocation location = new InputLocation(-1, -1, inputSource);
        location.setLocation(0, location);

        List<LifecycleMojo> mojos = goals.getMojos();
        if (mojos != null) {

            for (int i = 0; i < mojos.size(); i++) {
                LifecycleMojo mojo = mojos.get(i);

                GoalSpec gs = parseGoalSpec(mojo.getGoal());

                if (gs == null) {
                    logger.warn(

            buffer.append(" in plugin ").append(pluginDescriptor.getId());

            buffer.append(" among available goals ");
            List<MojoDescriptor> mojos = pluginDescriptor.getMojos();
            if (mojos != null) {
                for (Iterator<MojoDescriptor> it = mojos.iterator(); it.hasNext(); ) {
                    MojoDescriptor mojo = it.next();
                    if (mojo != null) {

* Implications for Mojo Execution

** Deployment mojos

  The concept of deployment is dependent on the availability of a some
  remote repository. Just as above, if that repository is not using
  file:// (which is highly likely to be the case), or the repository is
  not on a local filesystem, deployment will fail when offline.

** Testing mojos

  This can be a problem if the tests are more than simple unit tests;

@Named
@Singleton
public class DefaultMojosExecutionStrategy implements MojosExecutionStrategy {
    @Override
    public void execute(List<MojoExecution> mojos, MavenSession session, MojoExecutionRunner mojoRunner)
            throws LifecycleExecutionException {
        for (MojoExecution mojoExecution : mojos) {
            mojoRunner.run(mojoExecution);
        }
    }
