android - Gitlab CI gradle 依赖缓存

Question

我在 Gitlab CI 上构建 android，每次下载依赖项都很烦人。我试过缓存:

$HOME/.gradle/
$HOME/.gradle/caches/
$GRADLE_HOME/caches/
$HOME/.m2/
.gradle/
build/
app/build/

我的 .gitlab-ci.yml 的第 26594 次迭代是 here .我已经在我的构建环境中安装了 gradle，因为没有缓存 gradlew 每次都会下载它，这会花费更多时间。我用于构建的图像是 here .我的CI服务器启动脚本可以找到here .我假设，如果缓存有效，我将不会在每次构建时看到下载的依赖项列表。

构建日志:

原来另一篇文章对此有答案!有一个变通方法是运行 before_script 将 GRADLE_HOME 设置为您的项目目录，然后您可以使用 cache 指令获取该目录。

before_script:
    - export GRADLE_USER_HOME=`pwd`/.gradle

cache:
  paths:
     - .gradle/wrapper
     - .gradle/caches

build:
  stage: build
  script:
     - ./gradlew assemble

test:
  stage: test
  script:
     - ./gradlew check
