Fallback to standard folder structure for resolution / artifact download when POM file is missing

Context :
While most artifact on public repo contain artifact automatically generated (i.e including a POM file by default), private repo have their artifact manually uploaded, without the corresponding POM file. This is not a good practice, however other build system (gradle) seems to fallback in this case and download/use the artifact JAR/AAR anyway (if present) and assume no dependencies.

Request/Suggestion:
Follow the same mechanism. It will help companies using their own artifact servers, when proper POM file uploads have been neglected.

The issue identifies resolution and artifact-download behavior, with JAR/AAR fallback when a POM is absent. Start by locating those paths and their existing tests; done means an artifact without a POM resolves and downloads successfully while being treated as having no dependencies.
