Java Modules are a feature of Java itself, available since Java 9, that allows for better encapsulation.

In Gradle, each _source set_ containing Java sources can be turned into a module by adding a `module-info.java` file.
Typically, in a project with Java Modules like this one, the _main_ source set of a subproject represents a module.

- the configuration `mongodbSupportRuntimeElements`, used by consumers to fetch the artifacts and runtime dependencies of this feature

A feature should have a _source set_ with the same name.
Gradle will create a `Jar` task to bundle the classes built from the feature source set, using a classifier corresponding to the kebab-case name of the feature.
