GitLab Gradle运行缓存不起作用

Question

我使用GitLab Runner作为CI来构建Android项目，但是缓存不起作用。我的。它从https://gist.github.com/daicham/5ac8461b8b49385244aa0977638c3420进行了修改。

image: runmymind/docker-android-sdk:latest 
variables: 
    GRADLE_USER_HOME: $CI_PROJECT_DIR/.gradle 
stages: 
    - build 
debug: 
    stage: build 
    script: 
    - set +e 
    - du -sh $CI_PROJECT_DIR/.gradle/wrapper 
    - du -sh $CI_PROJECT_DIR/.gradle/caches 
    - set -e 
    - ./gradlew assembleDebug 
    - mkdir artifacts 
    - cp mobile/build/outputs/apk/*.apk artifacts/ 
    - cp wear/build/outputs/apk/*.apk artifacts/ 
    cache: 
    paths: 
     - .gradle/wrapper/ 
     - .gradle/caches/ 
     - build/ 
     - mobile/build/ 
     - wear/build/ 
    artifacts: 
    name: "project_${CI_JOB_NAME}_${CI_COMMIT_REF_NAME}_${CI_COMMIT_SHA}" 
    expire_in: 2 weeks 
    paths: 
     - artifacts/

我一直在使用gradle这个参数来设置用户的gradle家，积极指定.gradle/缓存等也尝试过，但没有一次成功。

任何想法？

如果您使用Gitlab < 9.0，则添加以指定缓存必须在不同管道之间共享。

尝试添加key: $CI_PROJECT_NAMEcache下：

image: runmymind/docker-android-sdk:latest 
variables: 
    GRADLE_USER_HOME: $CI_PROJECT_DIR/.gradle 
stages: 
    - build 
debug: 
    stage: build 
    script: 
    - set +e 
    - du -sh $CI_PROJECT_DIR/.gradle/wrapper 
    - du -sh $CI_PROJECT_DIR/.gradle/caches 
    - set -e 
    - ./gradlew assembleDebug 
    - mkdir artifacts 
    - cp mobile/build/outputs/apk/*.apk artifacts/ 
    - cp wear/build/outputs/apk/*.apk artifacts/ 
    cache: 
    key: $CI_PROJECT_NAME 
    paths: 
     - .gradle/wrapper/ 
     - .gradle/caches/ 
     - build/ 
     - mobile/build/ 
     - wear/build/ 
    artifacts: 
    name: "project_${CI_JOB_NAME}_${CI_COMMIT_REF_NAME}_${CI_COMMIT_SHA}" 
    expire_in: 2 weeks 
    paths:
