Problem when launching Maven builds with MavenEmbedder

Question

I want to compile a project using the MavenEmbedder. Thus, I use this code:

    Configuration config = new DefaultConfiguration();
    config.setUserSettingsFile(new File("..."));
    config.setClassLoader(Thread.currentThread().getContextClassLoader());
    ConfigurationValidationResult validationResult = MavenEmbedder.validateConfiguration(config);
    if (validationResult.isValid()) {
        try {
            MavenEmbedder embedder = new MavenEmbedder(config);
            MavenExecutionRequest request = new DefaultMavenExecutionRequest();
            request.setBaseDirectory("...");
            request.setGoals(Arrays.asList(new String[] { "clean", "install" }));
            MavenExecutionResult result = embedder.execute(request);
            if (result.hasExceptions()) {
                List<Exception> exceptions = result.getExceptions();
                for (Exception e : exceptions) {
                    e.printStackTrace();
                }
            }
        } catch (MavenEmbedderException e) {
            e.printStackTrace();
        }
    }

When I run this code, I get this log, which show me an error:

I've looked to my local repository, and the plugin org.apache.maven.plugins:maven-install-plugin:2.2 is present.

What is the problem with my code? How to solve it?

Edit: If I simulate the mvn clean package command instead of the mvn clean install, i.e. having:

request.setGoals(Arrays.asList(new String[] { "clean", "package" }));

then the compilation works without problems...
