一、环境准备
1. 基础环境要求
- Jenkins Server：已安装JDK 11+，建议使用Linux服务器（Ubuntu/CentOS）
- Flutter SDK：全局安装或通过工具动态管理
- 构建代理节点：
- Android构建：需Android SDK、Gradle、NDK（可选）
- iOS构建：必须使用Mac节点，安装Xcode、CocoaPods
- 推荐插件：
Flutter Plugin # Flutter环境管理 Android Emulator Plugin # 模拟器测试 Fastlane Plugin # iOS自动化部署 Blue Ocean # 流水线可视化
2. Flutter环境配置（以Linux为例）
# 在Jenkins全局工具配置中添加Flutter
sudo mkdir /opt/flutter
sudo git clone https://github.com/flutter/flutter.git /opt/flutter
export PATH="$PATH:/opt/flutter/bin"
flutter doctor
二、Pipeline核心流程设计
1. 典型CI/CD流程
2. Jenkinsfile示例（多平台）
pipeline {agent anyenvironment {FLUTTER_HOME = '/opt/flutter'PATH = "$FLUTTER_HOME/bin:$PATH"}stages {stage('Setup') {steps {sh 'flutter doctor -v'sh 'flutter pub get'}}stage('Analyze') {steps {sh 'flutter analyze'}}stage('Test') {parallel {stage('Unit Test') {steps { sh 'flutter test' }}stage('Widget Test') {steps { sh 'flutter test integration_test/' }}}}stage('Build') {parallel {stage('Android') {when { branch 'dev' }steps {sh '''flutter build apk --release \--dart-define=API_ENV=prod \--target-platform android-arm64'''archiveArtifacts artifacts: 'build/app/outputs/flutter-apk/*.apk'}}stage('iOS') {agent { label 'mac' } // 指定Mac节点when { branch 'release' }steps {sh '''flutter build ipa --export-options-plist=ios/ExportOptions.plist \--dart-define=API_ENV=prod'''stash name: 'ios_build', includes: 'build/ios/ipa/*.ipa'}}}}stage('Deploy') {steps {script {if (env.BRANCH_NAME == 'release') {sh 'fastlane deliver' // iOS自动上传App Store} else {sshPublisher(transfers: [sshTransfer(remoteDirectory: '/var/www/test-env',sourceFiles: 'build/app/outputs/**/*.apk')])}}}}}post {always {junit '**/test-results/**/*.xml' // 测试报告emailext body: '构建详情：${BUILD_URL}', subject: 'Flutter构建完成'}}
}
三、关键配置详解
1. 多环境变量管理
// 使用参数化构建
parameters {choice(name: 'BUILD_ENV',choices: ['dev', 'staging', 'prod'],description: '选择构建环境')
}// 动态注入环境变量
environment {API_URL = sh(script: 'echo $BUILD_ENV | tr "[:lower:]" "[:upper:]"', returnStdout: true).trim()
}
2. iOS证书自动化（Fastlane集成）
# Fastfile 配置示例
lane :deploy doincrement_build_numbermatch(type: "appstore")build_app(scheme: "Release",export_method: "app-store")upload_to_app_store(api_key_path: "auth_key.json",skip_metadata: true)
end
3. Android签名配置
# 在Jenkins凭据管理中添加签名密钥
flutter build apk \--release \--keystore=${KEYSTORE_PATH} \--store-password=${STORE_PASSWORD} \--key-alias=${KEY_ALIAS} \--key-password=${KEY_PASSWORD}
四、性能优化技巧
1. 依赖缓存加速
stage('Cache') {steps {cache([[$class: 'ArbitraryFileCache', path: '/root/.gradle/caches', includes: '**/*.jar'],[$class: 'FlutterPubCache', path: '${WORKSPACE}/.pub-cache']])}
}
2. 热重启构建（增量更新）
# 仅当pubspec.yaml变更时触发全量构建
def hasDependencyChanged() {return sh(script: 'git diff --name-only HEAD~1 HEAD | grep pubspec.yaml',returnStatus: true) == 0
}
五、常见问题解决方案
1. iOS构建错误处理
问题现象：
Code Signing Error: No profile found
解决方案：
- 使用Fastlane Match同步证书
- 在Jenkins中添加Apple开发者账户凭据
security import dev.p12 -k ~/Library/Keychains/login.keychain -P $CERT_PASSWORD
2. Android构建内存溢出
调整Gradle配置：
# gradle.properties
org.gradle.jvmargs=-Xmx4096m -XX:MaxPermSize=1024m
3. Flutter版本冲突
多版本管理：
stage('Setup Flutter') {steps {flutterInstall('3.13.0') // 使用Flutter插件指定版本}
}
六、扩展实践
1. 自动化测试集成
# integration_test/driver.dart
void main() {integrationDriver(responseDataPath: 'integration_test/responses.json',onScreenshot: (name, bytes) async {final image = File('screenshots/$name.png');await image.create(recursive: true);await image.writeAsBytes(bytes);return true;},);
}
2. 代码质量门禁
stage('Quality Gate') {steps {sh 'flutter pub run dart_code_metrics:metrics analyze lib'sh 'flutter pub run dart_code_metrics:metrics check-unused-code lib'sonar(properties: '''sonar.projectKey=flutter_appsonar.dart.analysis.reportPath=metrics_report.json''')}
}
七、完整CI/CD架构示例
GitHub/GitLab│ˇ Webhook触发
Jenkins Server (Master)├── Linux Agent: Android构建/测试└── Mac Agent: iOS构建/签名│ˇFirebase App Distribution # 测试分发│ˇApp Store/Play Console # 生产发布
通过以上实践，您可以将Flutter项目的构建、测试、打包和发布流程全面自动化。建议：
- 版本控制：将Jenkinsfile纳入代码仓库
- 安全加固：使用Vault管理签名密钥
- 监控告警：集成Prometheus监控构建资源使用
- 渐进式交付：通过Codepush实现热更新
让Flutter的跨平台优势与Jenkins的自动化能力完美结合，打造高效的移动端CI/CD流水线！
