1，安装：brew install jenkins
2，命令行里：jenkins 回车，第一次会生成密码和保存密码的路径如：/Users/uname/.jenkins/secrets/initialAdminPassword
3，Jenkins中配置Xcode工程：
Manage Jenkins->pluginManager->available 查找xcode插件安装
4，创建一个新任务,输入项目名称，选择“构建一个自由风格的软件项目”
General设置Discard old builds，This project is parameterized ：name iOS_BRANCH branch:*/${iOS_BRANCH},设置分支参数choice parameter,multi-line string parameter设置蒲公英等描述信息
5,Additional Behaviours,advanced clone betaviours, fetch tags,Shallow clone,Shallow clone depth0,timeout 60;
6, Build -> execute shell #sh /Users/aaa/hello.sh $BUILD_NUMBER $WORKSPACE Release
7, 安装上传到蒲公英的插件
遇到问题jenkins启动不了，使用jenkins --httpPort=8080启动，端口占用后换端口号
脚本如下：
pod install
if [ ! -d build ];then
mkdir build
fi
PROJECT_NAME=${JOB_NAME}
# 1 clean
xcodebuild clean -workspace $WORKSPACE"/"$PROJECT_NAME".xcworkspace" -configuration Release -scheme $PROJECT_NAME
# # 2 导出 archive
xcodebuild archive -workspace $WORKSPACE"/"$PROJECT_NAME".xcworkspace" -scheme $PROJECT_NAME \
-archivePath ${PROJECT_NAME}.xcarchive -allowProvisioningUpdates
# 3 导出ipa
xcodebuild -exportArchive -archivePath ${PROJECT_NAME}.xcarchive -exportPath ./build -exportOptionsPlist ExportOptions.plist
# 上传到蒲公英 / 或者用插件也行 | ukey apikey都是和app对应的
curl -F "file=@./build/"${PROJECT_NAME}".ipa" \
-F "uKey=key" \
-F "_api_key=sdjfklasdjfklsd" \
-F "buildUpdateDescription=${PGYER}" \
