> We are currently de-facto limited to Maven 3.2.5 because our packaging relies on the shade-plugin modifying the dependency tree at runtime when bundling dependencies, which is no longer possible on Maven 3.3+.
> Being locked in to such an old Maven version isn't a good state to be in, and the contributor experience suffers as well.
> I've been looking into removing this limitation by explicitly marking every dependency that we bundle as {{optional}} in the poms, which really means {{non-transitive}}. This ensures that the everything being bundled by one module is not visible to other modules. Some tooling to capture developer mistakes were also written.
> Overall this is actually quite a nice change, as it makes things more explicit and reduces inconsistencies (e.g., the dependency plugin results are questionable if the shade-plugin didn't run!); and it already highlighted several problems in Flink.
> This change will have no effect on users or the released poms, because the dependency-reduced poms will be generated as before and remove all modified dependencies.
