根据@Jing Li的最新建议。这是我的gitlab-ci.yml版本

image: openjdk:8-jdk

variables:
  ANDROID_COMPILE_SDK: "30"
  ANDROID_BUILD_TOOLS: "29.0.2"
  ANDROID_COMMAND_LINE_TOOLS: "6858069"
  GRADLE_OPTS: "-Dorg.gradle.daemon=false"

before_script:
  - export GRADLE_USER_HOME=$(pwd)/.gradle
  - chmod +x ./gradlew
  - apt-get --quiet update --yes
  - apt-get --quiet install --yes wget tar unzip lib32stdc++6 lib32z1
  - mkdir -p android-sdk-linux/cmdline-tools
  - export ANDROID_SDK_ROOT=$PWD/android-sdk-linux
  - cd android-sdk-linux/cmdline-tools
  - wget --quiet --output-document=android-sdk.zip https://dl.google.com/android/repository/commandlinetools-linux-${ANDROID_COMMAND_LINE_TOOLS}_latest.zip
  - unzip android-sdk.zip
  - rm android-sdk.zip
  - mv cmdline-tools version
  - echo y | version/bin/sdkmanager "platforms;android-${ANDROID_COMPILE_SDK}" >/dev/null
  - echo y | version/bin/sdkmanager "platform-tools" >/dev/null
  - echo y | version/bin/sdkmanager "build-tools;${ANDROID_BUILD_TOOLS}" >/dev/null
  - export PATH=$PATH:$ANDROID_SDK_ROOT/platform-tools/
  # temporarily disable checking for EPIPE error and use yes to accept all licenses
  - set +o pipefail
  - yes | version/bin/sdkmanager --licenses
  - set -o pipefail
  - cd ../../
  - chmod +x ./gradlew

cache:
  key: ${CI_PROJECT_ID}
  paths:
    - .gradle/

这似乎是sdkmanager定位SDK安装文件夹的方式的错误。

一种变通方法是设置标志——sdk_root。您可以将ANDROID_HOME声明移动到更高的位置，然后在后续命令中使用它。

 - export ANDROID_HOME=$PWD/android-sdk-linux
 - yes | android-sdk-linux/tools/bin/sdkmanager --sdk_root=${ANDROID_HOME} --licenses
 - android-sdk-linux/tools/bin/sdkmanager --sdk_root=${ANDROID_HOME} "platform-tools" "platforms;android-${ANDROID_COMPILE_SDK}" >/dev/null

同时，将毛毯许可接收命令移动到第一个命令，清理回滚部分。

奇怪的是，如果你运行sdkmanager——sdk_root=${ANDROID_HOME} "tools"，它会把工具从3.6.0升级到26.1.1,sdkmanager就不再有这个问题了。这个更新需要花费时间和带宽，对于解决方案来说并不是完全必要的。

这里总结了几篇有用的文章，对于想要快速片段的人，例如插入Dockerfile，下面的脚本对我来说很有用:

RUN mkdir -p /opt/android/cmdline-tools/latest \
    && cd /opt/android/cmdline-tools/latest \
    && wget https://dl.google.com/android/repository/commandlinetools-linux-6858069_latest.zip \
    && bsdtar --strip-components=1 -xvf commandlinetools-linux-6858069_latest.zip \
    && yes | bin/sdkmanager --licenses \
    && bin/sdkmanager "build-tools;29.0.2" "platforms;android-29" \
    && rm commandlinetools-linux-6858069_latest.zip

It just requires bsdtar to be installed (it's usually packaged in popular distributions). Android platform/build tools version 29 are installed, and Android sdk root will be then located in /opt/android. While this setup works for me without warnings as it is, I have an issue when reinstalling packages already installed, or possibly installing different version of the packages: it clashes with packages already present and create bogus directories in the sdk root, with -2, -3 suffixes. These directories are then ignored, and warnings like Observed package id 'emulator' in inconsistent location are printed, so this behavior is definitely not desirable. If you have a fix for that please write it in the comments or, if you are confident enough, just edit the script with the exact fix.

从Android开发者网站下载新的cmdline-tools需要遵循以下目录结构。

安装SDK(任何方法)的第一个要求是安装Java并设置JAVA_HOME路径。 然后，SDK命令行工具需要安装路径，否则会抛出NullPointerException。 要克服这个问题，只需传递你想要安装SDK的路径，参数为“——sdk_root” 如。Sdkmanager.bat "platform-tools" "platforms;android-"——sdk_root=

对于那些在Windows 10/x64上为Appium安装Android命令行工具的人，请执行以下操作:

Download latest Command line tools from android i.e. commandlinetools-win-6200805_latest.zip Unzip the downloaded file Create directory for storing commandline tools somewhere on your disk, with following path included: android/cmdline-tools/latest Basically when You unzip this Cmd line tools, just rename tools directory to latest and make sure You put this latest folder in android/cmdline-tools directory somewhere on your disk Create ANDROID_HOME environment variable for directory that stores the cmdline tools directory location like: C:\YourLocationWhereYouStoreTheDirectory\android\cmdline-tools\latest Create new entry in Path environment variable as %ANDROID_HOME%\bin
