This is an issue caused by the mutual dependency of the two projects: the Infinispan release depends on the Hibernate Search, and produces artifacts which hardcode the version number of the expected Search version - and the expected Infinispan version that Search used to use.
When building a new version of Hibernate Search, we then need to provide an alias for the previous slot as that's what Infinispan is expecting us to use (even tough we did catch up).

Complex, but just a temporary solution until we finalize the module migration.
