OSGi: does RestClientBuilder (non-CDI) require MP Config at runtime?

Hi!

I’m trying to integrate a 3rd-party component that uses RestClientBuilder programmatically, as far as I can tell. Reading the spec, I understand that “it is possible to use MicroProfile Config”, if one uses CDI. That should imply that non-CDI implementations shouldn’t require MP Config at runtime. However, the OSGi resolver returns this:

Unable to resolve org.eclipse.microprofile.rest.client/2.0.0: missing requirement [org.eclipse.microprofile.rest.client/2.0.0] osgi.wiring.package; filter:="(&(osgi.wiring.package=org.eclipse.microprofile.config)(version>=2.0.0)(!(version>=3.0.0)))"
[caused by: Unable to resolve org.eclipse.microprofile.config/2.0.0: missing requirement [org.eclipse.microprofile.config/2.0.0] osgi.serviceloader; osgi.serviceloader=org.eclipse.microprofile.config.spi.ConfigProviderResolver; filter:="(osgi.serviceloader=org.eclipse.microprofile.config.spi.ConfigProviderResolver)"; effective:=active]

What am I missing (literally)? Do I have to provide a service implementing the ConfigProviderResolver interface, even if RestClientBuilder is used only programmatically?

Thanks

Hi @brevilo - yes, the CDI and MP Config dependencies should be considered optional. This is a bug. Thanks for reporting it - I’ll try to have a fix out shortly.
