To use the snapshot version of the plugin add this to settings.gradle.kts:

pluginManagement {
  repositories {
    maven {
      name = "JooqDockerPluginSnapshotRepo"
      url = uri("https://maven.pkg.github.com/monosoul/jooq-gradle-plugin/")
      credentials {
        username = "<your GitHub username>"
        password = "<your GitHub access token with read:packages scope>"
      }
    }
    gradlePluginPortal()
  }
}

And this to build.gradle.kts:

plugins {
  id("dev.monosoul.jooq-docker") version "SNAPSHOT-4369ee607a2aeba12f26a89c86b528ed0939c682"
}
