Score

I chose 8 points as a medium complexity method and use it as 100%. This means that all the methods above 100% are good candidates for splitting/improving. The formula is: percentage = points / 8 * 100

  • Update version in gradle.propertied
  • Update version and description in CHANGELOG.md
  • Run ./gradlew publishPlugin
  • Push to repo with the proper tag
