Change Maven Dependency version with Java

Question

I'm trying to write a maven plugin that is able to auto-update my dependencies. I have a working plug-in that, for now, just compile the maven project it's executed on. I am able to get de Dependency objects, but for I'm not looking for a way to find the possible versions to update to. Is there a way that allows me to check for new versions (local and from central)?

@Override
public void execute() {
    final File directory = project.getBasedir();
    final String[] arguments = {"clean compile"};

    LOGGER.info(String.format("Execute maven at '%s': %s", directory, Arrays.toString(arguments)));
    //System.setProperty("maven.multiModuleProjectDirectory", directory.getAbsolutePath());
    final MavenCli mavenCli = new MavenCli();
    final ByteArrayOutputStream stdOutStream = new ByteArrayOutputStream();
    final ByteArrayOutputStream stdErrStream = new ByteArrayOutputStream();
    final PrintStream stdOutPrint = new PrintStream(stdOutStream);
    final PrintStream stdErrPrint = new PrintStream(stdErrStream);
    final int exitCode = mavenCli.doMain(arguments, directory.getAbsolutePath(), stdOutPrint, stdErrPrint);
    for(Dependency dep : project.getDependencies()) {
        LOGGER.info(String.format("Dependency: %s:%s, version %s", dep.getGroupId(), dep.getArtifactId(), dep.getVersion()));
    }

Instead of implementing something that can be done by other plugin, invoke that plugin with your needs from your plugin.
