I'm quite unexperienced with Ivy's Java APIs. Thus, may anybody confirm that this solution
is the way to go?

So far, I've create a repository descriptor from an upate-site URL, saved the ivy descriptor
to disc (not really needed I guess), and manually downloaded the jar file to local disc:

RepoDescriptor repo = loadRepositoryDescriptor(url).get();

for (final ModuleDescriptor module : (Set<ModuleDescriptor>){
  // save the ivy descriptor of the osgi bundle:
  File ivyFile = File.createTempFile(module.getModuleRevisionId().getName() + "_tmp_", ".xml");

  // download each artifact:
  for (final Artifact artifact : module.getAllArtifacts()) {

    // the url returned by the artifact always starts with "file:http://", is this ok?
    URL artifactUrl = new URL(artifact.getUrl().toExternalForm().replace("file:", ""));
    File createTempFile = File.createTempFile("temp", ".jar");

    // download the jar to local disc
    FileUtil.copy(artifactUrl, createTempFile, new CopyProgressListener() { ... }

    // install somehow into a local ivy repository. How is this done?
    // Are there any code examples? Which Method is relevant for doing this?
