We found out, that is better to cache the whole .gradle-folder. This should be used only once per project. If k8s used for gitlab-runner, then you should turn the daemon off.

gitlab-ci.yaml:

variables:
  GRADLE_OPTS: "-Dorg.gradle.daemon=false" # no gradle-daemon on k8s

# ...

buildJar:
  stage: build
  image: gradle:5.6.4-jdk11
  before_script:
    - export GRADLE_USER_HOME=`pwd`/.gradle
  script:
    - gradle assemble
  cache:
    key: "gradleCache"
    paths:
      - .gradle
