To make the my libraries accessible to others, I could simply place the jar file somewhere, such as the “download” area of the project’s GitHub repository. This works fine, as long as the jar has no dependencies. However, if my jar depends on other libraries, anyone using my code has to chase down and install those dependencies. A better solution is to create and deploy a Maven file, since the POM file will capture those dependencies.

As it happens, SBT has excellent support for Maven. It will generate a POM automatically, and it will publish to a Maven repository. In most cases, you never have to write a single line of Maven XML; SBT handles all that for you.
