OSGi Resolution error "osgi.wiring.package"

Question

I'm working on a OSGi project (I'm fairly new with it). It is an existing source code, so I'm adding a new bundle called "io.openems.edge.dieselgenerator", when I do the resolution process I get that it failed with the following message:

Resolution failed. Capabilities satisfying the following requirements could not be found:
[<<INITIAL>>]
  ⇒ osgi.identity: (osgi.identity=io.openems.edge.dieselgenerator)
      ⇒ [io.openems.edge.dieselgenerator version=1.0.0.202107141719]
          ⇒ osgi.wiring.package: (osgi.wiring.package=io.openems.edge.simulator)
[osgi.cmpn version=7.0.0.201802012110]
  ⇒ osgi.unresolvable: (&(must.not.resolve=*)(!(must.not.resolve=*)))
[ch.qos.logback.classic version=1.2.3]
  ⇒ osgi.wiring.package: (&(osgi.wiring.package=ch.qos.logback.core.util)(version>=1.2.0)(!(version>=2.0.0)))
[org.eclipse.jetty.alpn.server version=9.4.35.v20201120]
  ⇒ osgi.wiring.package: (&(osgi.wiring.package=org.eclipse.jetty.alpn)(version>=1.1.3))

I see that there's a problem with osgi.wiring.package: (osgi.wiring.package=io.openems.edge.simulator). io.openems.edge.simulator is an existing bundle that I added to my new bundle as a dependencies. Any idea of what's happening? Or should I provide more information that I don't know?

Thank you

What the message is telling you is that none of the bundles installed in the OSGi container provide/export the package that your bundle or one of its dependencies requires.

It could be that you're missing bundle that provides org.eclipse.jetty.alpn package or that you're trying to install your bundle before its dependencies are available.

Or should I provide more information that I don't know?

It could help other to help you if they knew how your project is setup and where you're running your OSGi bundles i.e Apache Karaf, Eclipse IDE or somewhere else.
