Keep in mind:

- If you’re adding a dependency with OS mentioned in an artifact name (`darwin`, `mac`, `osx`, `linux`, `windows`), remember to add them to 
  `implicitDependencies` configuration or update `resolveDependencies` task if needed. `resolveDependencies` should resolve all dependencies
  including dependencies for different platforms.
