#### Formatting

We are in the process of migrating towards automatic formatting Java file
using [spotless], backed by the Eclipse formatter. **We strongly recommend
installing using the [Eclipse Code Formatter] plugin** so that you can
apply the correct formatting directly in IntelliJ.  The configuration for
the plugin is held in `.idea/eclipseCodeFormatter.xml` and should be
