As a plugin developer that likes to live on the bleeding edge, I want to use jigsaw modules for my plugins. Bukkit however does not provide a module, so I'll just have to use the file-name based module name `bukkit`. This is considered bad practice, especially if I publish my plugin on a repository, or on the SpigotMC forums for that sake.

Now that Java 11 (which will be the new LTS release) is around the corner it makes sense for bukkit to provide a module. The easiest way to do this is specifying an automatic module in bukkit's pom.xml since it doesn't require the project to target Java 9 (or later) and all packages will be exported. Since module names must be unique I suggest to use the following format: <domain>.<artifact> all in lowercase. For the bukkit api that would look as follows:

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>3.1.0</version>
<configuration>
<archive>
<manifestEntries>
<Automatic-Module-Name>org.bukkit.bukkit</Automatic-Module-Name>
</manifestEntries>
</archive>
</configuration>
</plugin>
