Re: [tycho-user] How to extend tycho-osgi-runtime via TychoOsgiRuntimeAr

["Sievers, Jan" <jan.sievers@xxxxxxx>]

I never tried extending the tycho OSGi runtime and there are no tests covering this scenario, so I can't promise much.
But yes, a bug with a sample project would help focus the discussion

Regards
Jan

    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):

            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?
