**Is your feature request related to a problem? Please describe.**



Keeping Maven dependency versions consistent is hard.



**Describe the solution you'd like**



I would like a BOM published to Maven central.



**Describe alternatives you've considered**



Users of the library can keep their Maven dependency versions consistent properties.



**Additional context**



Maven BOMs have become a popular method for multi-module library projects to help users keep their dependencies up to date. Many popular libraries publish a BOM, such as [guava](https://central.sonatype.com/artifact/com.google.guava/guava-bom/versions).
