Re: [tycho-user] How to extend tycho-osgi-runtime via TychoOsgiRuntimeArtifacts?
Hello Jan,

thanks for your answers. 

I followed your advices/suggestions and get the following outcome:

====================== CUT HERE =======================

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/5951a62696123bff26cead593ca54d7b124a70e6/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?
