Android bitbucket-pipelines.yml缓存

Question

我对位桶管道有以下脚本

我不确定如何优化它，我无法使缓存正常工作

pipelines:
  default:
    - step:
        name: Compiling Debug Build
        script:
            - echo y | android update sdk --filter "extra-android-m2repository" --no-ui -a
            - mkdir "${ANDROID_HOME}/licenses" || true
            - echo "8933bad161af4178b1185d1a37fbf41ea5269c55" > "${ANDROID_HOME}/licenses/android-sdk-license"
