flutter ios打包_使用 Travis CI 为 Flutter 项目打包 Android/iOS 应用

Travis CI 构建

Building Flutter APKs and IPAs on Travis 这篇文章详细介绍了如何在 Travis CI 上为 Flutter 项目打包 Android/iOS 应用，不过实际构建时存在几个问题，原文中的 .travis.yml 配置如下：

matrix:include:- os: linuxlanguage: androidlicenses:- 'android-sdk-preview-license-.+'- 'android-sdk-license-.+'- 'google-gdk-license-.+'android:components:- tools- platform-tools- build-tools-25.0.3- android-25- sys-img-armeabi-v7a-google_apis-25- extra-android-m2repository- extra-google-m2repository- extra-google-android-supportjdk: oraclejdk8sudo: falseaddons:apt:# Flutter depends on /usr/lib/x86_64-linux-gnu/libstdc++.so.6 version GLIBCXX_3.4.18sources:- ubuntu-toolchain-r-test # if we don't specify this, the libstdc++6 we get is the wrong versionpackages:- libstdc++6- fonts-droidbefore_script:- wget http://services.gradle.org/distributions/gradle-3.5-bin.zip- unzip -qq gradle-3.5-bin.zip- export GRADLE_HOME=$PWD/gradle-3.5- export PATH=$GRADLE_HOME/bin:$PATH- git clone https://github.com/flutter/flutter.git -b alpha --depth 1script:- ./flutter/bin/flutter -v build apk- os: osxlanguage: genericosx_image: xcode8.3before_script:- pip install six- brew update- brew install --HEAD libimobiledevice- brew install ideviceinstaller- brew install ios-deploy- git clone https://github.com/flutter/flutter.git -b alpha --depth 1script:- ./flutter/bin/flutter -v build ios --no-codesigncache:directories:- $HOME/.pub-cache

Android

wget - 403 Forbidden

这个错误发生在执行 wget http://services.gradle.org/distributions/gradle-3.5-bin.zip 的时候，把 gradle 的下载路径替换成 https 即可。

Remote branch alpha not found in upstream origin

这个错误发生在下载 Flutter 代码的阶段，原文中的配置会下载 Flutter 的 alpha 分支代码，但是目前 Flutter 的仓库已经没有 alpha 分支，切换到 stable 分支即可，即：git clone https://github.com/flutter/flutter.git -b stable --depth 1。

Failed to install the following Android SDK packages as some licences have not been accepted

详细错误信息如下：

[        ] > Failed to install the following Android SDK packages as somelicences have not been accepted.[        ]      build-tools;28.0.3 Android SDK Build-Tools 28.0.3[        ]      platforms;android-29 Android SDK Platform 29[        ]   To build this project, accept the SDK license agreements andinstall the missing components using the Android Studio SDK Manager.

这个错误是由于没有同意 Android SDK 的许可证协议，在 before_script 中加入如下配置即可：

yes | sdkmanager "platforms;android-29"
yes | sdkmanager "build-tools;28.0.3"

iOS

pip: command not found

这个错误在执行 pip install six 时遇到，经过实际验证构建 iOS 应用时并不需要此行配置，所以删掉即可。

Xcode 11.0 or greater is required to develop for iOS

原文中的配置使用的是 Xcode 8.3，最后打包时会提示此错误，将 osx_image 设置为 xcode11 即可。

最后完整可用的 .travis.yml 配置如下：

matrix:include:- os: linuxlanguage: androidlicenses:- 'android-sdk-preview-license-.+'- 'android-sdk-license-.+'- 'google-gdk-license-.+'android:components:- tools- platform-tools- build-tools-25.0.3- android-25- sys-img-armeabi-v7a-google_apis-25- extra-android-m2repository- extra-google-m2repository- extra-google-android-supportjdk: oraclejdk8sudo: falseaddons:apt:# Flutter depends on /usr/lib/x86_64-linux-gnu/libstdc++.so.6 version GLIBCXX_3.4.18sources:- ubuntu-toolchain-r-test # if we don't specify this, the libstdc++6 we get is the wrong versionpackages:- libstdc++6- fonts-droidbefore_script:- wget https://services.gradle.org/distributions/gradle-3.5-bin.zip- unzip -qq gradle-3.5-bin.zip- export GRADLE_HOME=$PWD/gradle-3.5- export PATH=$GRADLE_HOME/bin:$PATH- git clone https://github.com/flutter/flutter.git -b stable --depth 1- yes | sdkmanager "platforms;android-29"- yes | sdkmanager "build-tools;28.0.3"script:- ./flutter/bin/flutter -v build apk- os: osxlanguage: genericosx_image: xcode11before_script:- brew update- brew install --HEAD libimobiledevice- brew install ideviceinstaller- brew install ios-deploy- git clone https://github.com/flutter/flutter.git -b stable --depth 1script:- ./flutter/bin/flutter -v build ios --no-codesigncache:directories:- $HOME/.pub-cache

Codemagic

最后推荐 Codemagic 这个服务，提供云端打包 Flutter 应用的功能，省去了 Travis CI 配置的步骤，免费用户每月有500分钟的额度来执行构建。
