thanks for your answers.Â
I followed your advices/suggestions and get the following outcome:

It seems my maven core extension (now registered via .mvn/extensions.xml) triggers a whole lot of other components.
Obviously my extension has a dependency to org.eclipse.tycho:tycho-core, but for only one class.
Does this help?
Maybe I can setup a sample project, but this will take some time.
Thanks in advance,
Marco

another thing is to make sure the plexus descriptors are generated, like in
https://github.com/eclipse/tycho/blob/ 5951a62696123bff26cead593ca54d 7b124a70e6/pom.xml#L365-L377
otherwise dependency injection will not happen

  Looks like the OSGi runtime should be extensible but I never tried this.
  You may have to add it as a maven core build extension so the classloader sees it, i.e.
  <extensions>true</extensions>
  similar to tycho itself, see [1].
  this where you would have to start debugging (mvnDebug):
  https://github.com/eclipse/tycho/blob/master/tycho-core/ src/main/java/org/eclipse/ tycho/osgi/runtime/ TychoOsgiRuntimeLocator.java# L122

    Hello everybody,
    I want tycho to include my osgi-bundle into its runtime. (It registers a custom url via org.osgi.service.url.URLStreamHandlerService.)
    It does not work.
    What a tried so far:
    1. I wrote the osgi bundle that provides the service (BTW: build with tycho).
    2. I wrote a maven extension that exports a plexus component with role TychoOsgiRuntimeArtifacts and hint mycustomurl.
    3. I registered the extension in the parent pom of another tycho build where I want tycho to use my custom url in p2 repository loading.
    The extension is never loaded. Any ideas?
