Question

我有几个开源库，我已经设置了Travis CI。它们运行正常，但需要25分钟才能检查构建。大部分时间都浪费在下载依赖项和Android SDK平台上。

我目前在.travis.yml

中有以下内容

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

正如您所看到的，我已经缓存了几个gradle目录，但它仍然没有缓存Android SDK平台。我确信我缺少一些我仍需要缓存的目录。

有没有什么办法可以通过缓存那些SDK平台和依赖项来提高构建速度？

Answer 1

不推荐使用缓存SDK工具，但有可能，我过去做过，我会搜索样本

同时，请删除这些不必要的行以加快它并告诉我它是否有效。

    - 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，一个模拟器和特定组件，而不是像这样的列表：

- add-on
- extra

更新：我发现this build我正在使用这样的自定义路径缓存SDK工具附加功能：

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"

您不需要这样做，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don't want将完整的sdk工具保存到缓存中，包括所有系统映像。

缓存的目的是使安装特定于语言   依赖关系简单快捷，所以一切都与工具相关   Bundler，pip，Composer，npm，Gradle，Maven，应该进入   高速缓存中。

快速安装但下载速度慢的大型文件没有   从缓存中获益，因为从缓存中下载需要很长时间   从原始来源：


Android SDK

Debian软件包

JDK包

已编译的二进制文件

Default environment variables：

TRAVIS_BUILD_DIR：目录所在的绝对路径正在构建的存储库已复制到工作者身上。
