Since Java 9, Java provides a module system known as Jigsaw which allow library authors to restrict access of their internal packages and provide a better explicit dependency abstraction.

In order to benefit from this "new" feature, Java libraries need to provide a module-info.java file inside the jar artefact to declare what they requires and what they exports.

However since this can be non-trivial to become modular a important first step for library authors is to register a module-name to enable libraries depending on them to become modular without having to wait for modular refactoring work to be done. To register a module name a library simply need only to define the Automatic-Module-Name property in the META-INF/MANIFEST.MF file inside their jar artefact.

I suggest that this library should register the module name com.google.maps.
