在Travis CI中缓存Android SDK

noob 发表于 Dev

我没有几个可以在其中设置Travis CI的开源库。它们运行正常，除了需要25分钟以上的时间来检查构建。大多数时间都浪费在下载依赖项和Android SDK平台上。

我的.travis.yml中目前包含以下内容

language: android
jdk:
  - oraclejdk8
before_install:
- chmod +x gradlew
env:
  global:
   - ANDROID_API_LEVEL=24
   - EMULATOR_API_LEVEL=21
   - ANDROID_BUILD_TOOLS_VERSION=24.0.1
   - ANDROID_ABI=google_apis/armeabi-v7a
   - ADB_INSTALL_TIMEOUT=20 # minutes (2 minutes by default)

android:
  components:
    - tools
    - tools
    - platform-tools
    - build-tools-$ANDROID_BUILD_TOOLS_VERSION
    - android-$ANDROID_API_LEVEL
    - android-$EMULATOR_API_LEVEL
    - extra
    - add-on
    - extra-google-m2repository
    - extra-android-m2repository
    # Google Play Services
    - extra-google-google_play_services
    # Support library
    - extra-android-support

    - addon-google_apis-google-$ANDROID_API_LEVEL
    - addon-google_apis-google-$EMULATOR_API_LEVEL

    - sys-img-armeabi-v7a-addon-google_apis-google-$ANDROID_API_LEVEL
    - sys-img-armeabi-v7a-addon-google_apis-google-$EMULATOR_API_LEVEL

before_cache:
  - rm -f $HOME/.gradle/caches/modules-2/modules-2.lock
cache:
  directories:
    - $HOME/.gradle/wrapper
    - $HOME/.gradle/native
    - $HOME/.gradle/daemon
    - $HOME/.gradle/caches/jars-1
    - $HOME/.gradle/caches/2.3

before_script:
  - echo no | android create avd --force -n test -t android-21 --abi armeabi-v7a
  - emulator -avd test -no-skin -no-audio -no-window &
  - android-wait-for-emulator
  - adb shell input keyevent 82 &

script:
  - gradle clean check

如您所见，我已经缓存了一些gradle目录，但是仍然没有缓存Android SDK平台。我确定我缺少一些仍需要缓存的目录。

有什么办法可以通过缓存那些SDK平台和依赖项来加快构建速度？

阿尔贝德鲁

不建议您缓存SDK工具，但是有可能，我以前做过，我将搜索一个示例

同时，请删除这些不必要的行以加快速度并告诉我是否可行。

    - extra
    - add-on
    # Google Play Services
    - extra-google-google_play_services
    # Support library
    - extra-android-support
    - addon-google_apis-google-$ANDROID_API_LEVEL
    - sys-img-armeabi-v7a-addon-google_apis-google-$ANDROID_API_LEVEL

您只需要安装存储库，一个仿真器和特定组件，而不需要像这样的列表：

- add-on
- extra

更新：我找到了这个构建，其中使用如下自定义路径来缓存SDK工具的额外内容：

cache:
  apt: true
  directories:
    - ${TRAVIS_BUILD_DIR}/gradle/caches/
    - ${TRAVIS_BUILD_DIR}/gradle/wrapper/dists/
    - ${TRAVIS_BUILD_DIR}/android-sdk/extras/

env:
  global:
    - GRADLE_USER_HOME=${TRAVIS_BUILD_DIR}/gradle
    - ANDROID_HOME=${TRAVIS_BUILD_DIR}/android-sdk
    - SDK=${TRAVIS_BUILD_DIR}/android-sdk
    - PATH=${GRADLE_USER_HOME}/bin/:${SDK}/:${SDK}/tools/:${SDK}/platform-tools/:${PATH}

before_install:
  - echo "WARNING delete this when fixed"; export OLD_SDK=/usr/local/android-sdk-23.0.2;
                                           mkdir -p ${SDK};
                                           cp -u -R ${OLD_SDK}/platforms ${SDK}/platforms;
                                           cp -u -R ${OLD_SDK}/system-images ${SDK}/system-images;
                                           cp -u -R ${OLD_SDK}/tools ${SDK}/tools || echo "CP ERROR"

您无需这样做，直接将存储库所在的默认路径保存到缓存中：

/usr/local/android-sdk/extras

您不想保存完整的sdk工具来缓存包括所有系统映像。

缓存的目的是使安装特定于语言的依赖关系变得轻松快捷，因此与工具（如Bundler，pip，Composer，npm，Gradle，Maven）相关的所有内容都应放入缓存中。

快速安装但下载缓慢的大型文件无法从缓存中受益，因为它们从缓存中下载所需的时间与从原始源中下载所需的时间一样长：

Android SDK

Debian软件包

JDK套件

编译的二进制文件
