如何从命令行自动接受android库许可证？

Question

我正在使用gitlab-ci来构建我的android项目.经过大量搜索后,我发现了如何接受sdk许可证.但我在ConstraintLayout图书馆获得许可证不被接受的错误.这是我的.gitlab-ci.yml:

    image: openjdk:8-jdk

    variables:
    ANDROID_TARGET_SDK: "25"
    ANDROID_BUILD_TOOLS: "25.0.0"
    ANDROID_SDK_TOOLS: "24.4.1"

  before_script:
    - apt-get --quiet update --yes
    - apt-get --quiet install --yes wget tar unzip lib32stdc++6 lib32z1
    - wget --quiet --output-document=android-sdk.tgz https://dl.google.com/android/android-sdk_r${ANDROID_SDK_TOOLS}-linux.tgz
    - tar --extract --gzip --file=android-sdk.tgz
    - echo y | android-sdk-linux/tools/android --silent update sdk --no-ui --all --filter android-${ANDROID_TARGET_SDK}
    - echo y | android-sdk-linux/tools/android --silent update sdk --no-ui --all --filter platform-tools
    - echo y | android-sdk-linux/tools/android --silent update sdk --no-ui --all --filter build-tools-${ANDROID_BUILD_TOOLS}
    - echo y | android-sdk-linux/tools/android --silent update sdk --no-ui --all --filter extra-android-m2repository
    - echo y | android-sdk-linux/tools/android --silent update sdk --no-ui --all --filter extra-google-google_play_services
    - echo y | android-sdk-linux/tools/android --silent update sdk --no-ui --all --filter extra-google-m2repository
    - export ANDROID_HOME=$PWD/android-sdk-linux
    - chmod +x ./gradlew
    - chmod +x ./copy_licenses.sh
  build:
    script:
      - ./copy_licenses.sh
      - ./gradlew assembleDebug
    artifacts:
      paths:
      - app/build/outputs/

我拷入我的许可文件的$ANDROID_HOME/licenses使用copy_licenses.sh:

    #!/bin/bash
    # fail if any commands fails
    set -e
    # debug log
    set -x

    cp -a "./android-licenses" "$ANDROID_HOME/licenses"

执行此操作后,我收到此错误:

    FAILURE: Build failed with an exception.

    * What went wrong:
    A problem occurred configuring project ':app'.
    > You have not accepted the license agreements of the following SDK components:
      [Solver for ConstraintLayout 1.0.0-beta4, ConstraintLayout for Android 1.0.0-beta4].
      Before building your project, you need to accept the license agreements and complete the installation of the missing components using the Android Studio SDK Manager.
      Alternatively, to learn how to transfer the license agreements from one workstation to another, go to http://d.android.com/r/studio-ui/export-licenses.html

    * Try:
    Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

    BUILD FAILED

如何ConstraintLayout 1.0.0-beta4从命令行接受许可？
