The SLF4J API, on the other hand, is simply a detail of the logging API used by your bundles, or of the API used by the implementation that you’re bridging to the OSGi log service. Does that make sense? Yes that’s make sense agreed.

This, however, would be an important detail of your application because it would be dictated by the features you need and would affect the configuration that you write, as a result it ends up as an explicit requirement. The SLF4J API, on the other hand, is simply a detail of the logging API used by your bundles, or of the API used by the implementation that you’re bridging to the OSGi log service. Does that make sense? The run requirements are really just defining the things that you explicitly want to select. These will be things like application entry points (e.g. your Servlets/JAX-RS resources) and anything that you explicitly want to configure (and are therefore tied to the PID).

However, I understand there is clear distinction between both files and always need for dependency management (pom/build.gradle). But, there seem to be some commonality between both files when defining your bundles. For example sl4j is added as transitive dependences in the pom but may also needed to add to your run requirements if you using logservice bundle.

The enRoute projects set up their bndrun files to use standalone indexes generated by the bnd-indexer-maven-plugin. These indexes are generated using the dependencies from the pom file of the project. The benefit of this solution is that indexes can be generated for different dependency scopes, for example a testing index is generated which includes test-scoped dependencies. This index is then used by the debug bndrun to include things like the Felix Gogo shell and the Felix Web console, which are good for debugging, but should not be available when resolving/deploying a production application. To answer your original question, therefore: It seems, if we create an OSGI project we have to add dependencies to maven or gradle pom.xml build.gradle then we have add dependencies to our composite application .bndrun file. Adding the dependencies to your pom.xml is a necessary step. This is because the transitive dependency graph of your project determines the set of bundles that are available to the resolve and export operations. Also adding a dependency to your pom.xml does not require anything to be added to your bndrun file (although it may change the output of your next call to the resolver). The requirement that you add to your bndrun is different and is not about declaring dependencies. The bndrun runrequire instruction exists to define the outer surface and structure of your application, which can be further fine-tuned using blacklisting and other instructions. The closest analogy in a non-OSGi project would be an assembly descriptor for the maven-assembly plugin. The purpose of the bndrun is therefore to define the complete set of bundles make up your application, with the bnd-resolver-maven-plugin using your run requirements to generate that list for you. In general your run requirements list should be very small (often only one requirement), and not need updating even if the pom dependencies change. Hopefully this explanation helps you to see the difference between the two files and what they are trying to achieve.
