> When a plugin extension has a dependency on {{maven-aether-resolver}}, the components of this artifact are added into the plugin realm even though Maven Core already provides them. This is a regression introduced by the rename of this module to {{maven-resolver-provider}} in 3.5.0.
> This rename has kept all the classes of {{maven-aether-resolver}} for compatibility, therefore the old artifact name also needs to be exported by Maven Core in {{extension.xml}}.
> A visible side-effect of this is MDEPLOY-221, where the two {{MetadataGeneratorFactory}} components of {{maven-aether-provider}} (which are {{SnapshotMetadataGeneratorFactory}} and {{VersionsMetadataGeneratorFactory}}) are present twice as Guice bindings, and wrong metadata information is deployed as a consequence. This is due to the Flex Mojos plugin extension which depends on {{maven-aether-resolver}} used in the build.
