opentelemetry-java: Cannot use Gradle composite build

Is your feature request related to a problem? Please describe. I tried to develop a feature which requires code changes both in this repo and in java instrumentation repo. To verify that everything works I wanted to build instrumentation agent with changes from this repo using Gradle compose build. Unfortunately build failed:

Could not determine the dependencies of task ':smoke-tests:test'.
> Could not resolve all task dependencies for configuration ':smoke-tests:testRuntimeClasspath'.
   > Could not find io.grpc:grpc-api:.
     Required by:

It seems to me that bom support used by this repo prevents from including it into other projects.

I don’t know any other way to test instrumentation repo with unreleased changes from this project.
