缓存 .gitlab-ci.yml 文件中的所有数据

Question

我是Gitlab CI 的新手，我正在尝试在.gitlab-ci.yml 文件中使用缓存（在Android 平台上）。 gitlab ci 运行良好，但每次我将代码推送到 gitlab 时，CI 都会下载所有数据以再次运行它（每次推送的运行代码大约需要 30 分钟）。

我正在使用本教程中的方法 1 创建Gitlab CI：http://www.greysonparrelli.com/post/setting-up-android-builds-in-gitlab-ci-using-shared-runners/

我在 StackOverflow 上尝试了许多解决方案，在 Google 上尝试了另一个结果，但仍然无法缓存。

这是我的 .gitlab-ci.yml 文件：

image: openjdk:8-jdk

variables:
  ANDROID_TARGET_SDK: "24"
  ANDROID_BUILD_TOOLS: "24.0.3"
  ANDROID_SDK_TOOLS: "24.4.1"
  MAVEN_OPTS: -Dmaven.repo.local=/cache/maven.repository

before_script:
  - export GRADLE_USER_HOME=/cache/.gradle
  - apt-get --quiet update --yes
  - apt-get --quiet install --yes wget tar unzip lib32stdc++6 lib32z1
  - wget --quiet --output-document=android-sdk.tgz https://dl.google.com/android/android-sdk_r${ANDROID_SDK_TOOLS}-linux.tgz
  - tar --extract --gzip --file=android-sdk.tgz
  - echo y | android-sdk-linux/tools/android --silent update sdk --no-ui --all --filter android-${ANDROID_TARGET_SDK}
  - echo y | android-sdk-linux/tools/android --silent update sdk --no-ui --all --filter platform-tools
  - echo y | android-sdk-linux/tools/android --silent update sdk --no-ui --all --filter build-tools-${ANDROID_BUILD_TOOLS}
  - echo y | android-sdk-linux/tools/android --silent update sdk --no-ui --all --filter extra-android-m2repository
  - echo y | android-sdk-linux/tools/android --silent update sdk --no-ui --all --filter extra-google-google_play_services
  - echo y | android-sdk-linux/tools/android --silent update sdk --no-ui --all --filter extra-google-m2repository
  - export ANDROID_HOME=$PWD/android-sdk-linux
  - chmod +x ./gradlew

cache:
  key: "$CI_BUILD_NAME/$CI_BUILD_REF_NAME"
  paths:
  - .gradle/
  - build/
  - .m2/
  - $HOME/.gradle/caches/
  untracked: true

build:
  script:
    - ./gradlew assembleDebug
  artifacts:
    paths:
    - app/build/outputs/
