Package resolution fails when a dependency uses an SPM-plugin for code generation

[tachyonics]

Expected behavior

Compilation should complete as if the dependency wasn't using an SPM-plugin for code generation.

Actual behavior

Package resolution fails with

product 'SmokeFrameworkGenerateHttp1' required by package 'emptyexampleservice' target 'EmptyExampleOperationsHTTP1' not found in package 'smoke-framework-application-generate'.

Steps to reproduce

1. Use SPM to create a new package.
2. Clone the smoke-framework-examples repository locally.
3. Add the EmptyExampleService as a local dependency [1]
4. Try to resolve the dependencies, it should fail with the error

[1] .package(path: "${BASE_PATH}/smoke-framework-examples/EmptyExampleService"),

If possible, minimal yet complete reproducer code (or URL to code)

I have also tested this with non-local dependencies and the same error is encountered. The EmptyExampleService package itself correctly compiles.

thanks for reporting @tachyonics, to make sure we understand the issue correctly:

1. smoke-framework-examples uses plugins from smoke-framework-application-generate
2. when creating a new package that depends on smoke-framework-examples, the build of that package fails to resolve?

Thanks @tomerd, that is correct.
