Solution

Remove the lines where your com.zaxxer.hikari package relocation from maven's pom.xml so com/zaxxer/hikari/HikariConfig (and other classes) will be recognized.

<relocation>

  <pattern>com.zaxxer.hikari</pattern>
  <shadedPattern>com.massivecraft.factions.shade.com.zaxxer.hikari</shadedPattern>
</relocation>
