The build cache has anonymous read access, so you don't need to authenticate in order to use it. You can use a different build cache node by specifying `-DcacheNode=us` for a build cache node in the US or `-DcacheNode=au` for a build cache node in Australia.

If you are not getting cache hits from the build cache, you may be using the wrong version of Java. A fixed version (Java 11) is required to get remote cache hits.
