开源端到端流水线实践-需求与代码管理
业务的简称为demo，微服务架构。N多个微服务。服务命名：业务简称-应用名称-类型（demo-hello-service）。特性分支开发，版本分支发布。每个需求（任务/故事）对应一个特性分支。每个发布（release）对应一个版本分支。
1.需求与代码管理
Jira作为需求和缺陷管理，采用Scrum开发方法，jira中的项目名称与业务简称一致（demo）。Gitlab作为版本控制系统，每个Group对应一个业务，每个微服务对应一个代码库。
需求与代码关联：在jira中创建一个任务/故事，关联模块后自动在该模块创建一个以ISSUE（任务/故事）ID的特性分支。此时的模块等同于每个微服务的项目（代码库）名称。以下面图中为例：我们在demo项目中创建了一个模块demo-hello-service，其实对应的就是Gitlab代码库中demo组的demo-hello-service服务。
特性分支：创建好每个模块后，就可以实现需求与代码关联。例如：我们在Jira项目demo中创建一个问题，类型为故事（不受限制可为其他），重点是需要将改故事关联到模块（只有关联到模块，我们才能通过接口得知哪个问题关联的哪个代码库）。
版本分支：当特性分支开发完成以及测试验证完成后，基于主干分支创建一个版本分支，然后将所有的特性分支合并到版本分支。此时可以通过Jira中创建一个发布版本，然后问题关联发布版本（此动作表示该特性分支已经通过验证，可以合并）。自动完成版本分支的创建和特性分支到版本分支的合并请求。
2. 配置过程
需求与代码库关联，主要用到的工具链为: Jira + GitLab + Jenkins。Jira负责创建需求，配置webhook。Jenkins负责接收Jira webhook请求，然后通过接口实现GitLab项目分支创建。
特性分支自动化：当我们在jira上面创建了问题，此时会通过Jira的webhook触发对应的Jenkins作业，该Jenkins作业通过解析Jira webhook传递的数据，找到问题名称和模块名称。调用GitlabAPI 项目查询接口，根据模块名称找到代码库。调用GitLabAPI 分支创建接口，根据问题名称基于主干分支创建一个特性分支。任务结束。
版本分支自动化：Jira创建发布版本，Issue关联版本。自动在gitlab代码库基于master创建版本分支，并开启特性分支到版本分支的合并请求。
2.1 准备工作
在Jenkins， 创建一个Pipeline 作业并配置GenericTrigger 触发器，接收JiraWebhook数据。projectKey 参数表示Jira项目名称，webHookData 参数为Jira webhook的所有数据。token 是触发器的触发token，这里默认采用的作业名称（作业名称要唯一）。
triggers {
GenericTrigger( causeString: 'Trigger By Jira Server -->>>>> Generic Cause',
genericRequestVariables: [[key: 'projectKey', regexpFilter: '']],
genericVariables: [[defaultValue: '', key: 'webHookData', regexpFilter: '', value: '$']],
printContributedVariables: true,
printPostContent: true,
regexpFilterExpression: '',
regexpFilterText: '',
silentResponse: true,
token: "${JOB_NAME}"
) 在Jira项目中配置Webhook，勾选触发事件填写触发URL。http://jenkins.idevops.site/generic-webhook-trigger/invoke?token=demo-jira-service&projectKey=${project.key} (这个地址是jenkins Generictrigger生成的，这里不做过多的介绍)
Jira webhook数据参考， 这些参数可以在Jenkinsfile中通过readJSON格式化，然后获取值。
response = readJSON text: """${webHookData}"""
println(response)
//获取webhook的事件类型
env.eventType = response["webhookEvent"] {
"timestamp":1603087582648,
"webhookEvent":"jira:issue_created",
