NoClassDefFoundError: HikariCP with Maven

问题

I'm creating a Maven plugin (to hook into Spigot/Bukkit/BungeeCord) and am attempting to connect to a database. On startup, I get this error:

Exception encountered when loading plugin: WarCore
java.lang.NoClassDefFoundError: com/zaxxer/hikari/HikariDataSource

I've tried using the Maven dependency plugin, Maven assembly plugin, but I cannot find a solution.

Here's my current pom.xml:
