我在 Gitlab CI 上构建 android 并且每次下载依赖项都很烦人。我尝试缓存：
$HOME/.gradle/
$HOME/.gradle/caches/
$GRADLE_HOME/caches/
$HOME/.m2/
.gradle/
build/
app/build/
我的 .gitlab-ci.yml 的第 26594 次迭代在这里。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，这需要更多时间。我用于构建的图像在这里。我的 CI 服务器启动脚本可以在这里找到。我假设，如果缓存有效，我不会在每个构建中看到我的依赖项列表下载。
构建日志：
