前言

Jenkins 是一款流行的开源持续集成（Continuous Integration）工具，广泛用于项目开发，具有自动化构建、测试和部署等功能。

最近参加公司的集成测试平台的开发，在开发中遇到了不少问题，两个星期的迭代也即将完成，在这也用这篇博客记录下开发中的问题，供读者参考

公司的应用较多，所以需要了解这几种应用在jenkins中如何做构建，我自己参与的有两种commander的应用，一种是大数据类的，一个是我们服务端架构组的scala应用

1、大数据应用BigData

配置如下：

配置文件对应的xml文件：通过crul获取xml配置文件：http://host/job/tar_py_dwx_dev/config.xml

<project><actions/><description/><keepDependencies>false</keepDependencies><properties><com.dabsquared.gitlabjenkins.connection.GitLabConnectionProperty plugin="gitlab-plugin@1.5.5"><gitLabConnection/></com.dabsquared.gitlabjenkins.connection.GitLabConnectionProperty><hudson.plugins.promoted__builds.JobPropertyImpl plugin="promoted-builds@3.1"><activeProcessNames><string>Deploy DEV</string></activeProcessNames></hudson.plugins.promoted__builds.JobPropertyImpl></properties><scm class="hudson.plugins.git.GitSCM" plugin="git@3.8.0"><configVersion>2</configVersion><userRemoteConfigs><hudson.plugins.git.UserRemoteConfig><url>ssh://git@172.0.10.182:10022/bigdata/dwx.git</url><credentialsId>84f4be19-ea8d-4271-8cfb-42af8f507285</credentialsId></hudson.plugins.git.UserRemoteConfig></userRemoteConfigs><branches><hudson.plugins.git.BranchSpec><name>*/develop</name></hudson.plugins.git.BranchSpec></branches><doGenerateSubmoduleConfigurations>false</doGenerateSubmoduleConfigurations><submoduleCfg class="list"/><extensions/></scm><assignedNode>!macmini</assignedNode><canRoam>false</canRoam><disabled>false</disabled><blockBuildWhenDownstreamBuilding>false</blockBuildWhenDownstreamBuilding><blockBuildWhenUpstreamBuilding>false</blockBuildWhenUpstreamBuilding><triggers><hudson.triggers.SCMTrigger><spec>H/5 * * * *</spec><ignorePostCommitHooks>false</ignorePostCommitHooks></hudson.triggers.SCMTrigger></triggers><concurrentBuild>false</concurrentBuild><builders><hudson.tasks.Shell><command>project=dwx1 cd ${WORKSPACE} tar zcvf ${project}.tar.gz * aws s3 cp ${project}.tar.gz s3://lattebank-jenkins-build-dev/${JOB_BASE_NAME}/${BUILD_NUMBER}/ --region cn-north-1 rm -rf ${project}.tar.gz</command></hudson.tasks.Shell></builders><publishers/><buildWrappers/></project>

从xml中获取的信息有点和图中的配置文件有点对应不上

对于promotion的脚本在xml配置文件中是无法获取的，这时候就有一个问题，这种api是无法获取到promotion的的脚本，同时这也给我们的工作带来了极大的挑战，那也意味着单纯的通过这种方法是无法实现commander应用的部署，和通过平台的方式去直接操作jenkins的配置

但经过查询相关的api并不能找到相关的内容，经过不懈的努力，终于找到了和promote build 插件相关的api

查询：http://host/job/jobName/promotion/process/promotionName/config.xml

这个接口能获取到它的xml文件，但是并不能对该配置文件进行增加和修改

对此我自己封装了一些方法：

/** * @author chenlang * date 2018/5/7 */@Slf4jpublic class JenkinsPromotionUtils {   private static final String SUB_PATH_PROMOTION_COOMMAND = "/hudson.plugins.promoted__builds.PromotionProcess"; private static final String SUB_PATH_BUILD = "/buildSteps"; private static final String SUB_PATH_BUILDER_SHELL_COMMAND = "/hudson.tasks.Shell/command"; private static final String PATH_PROMOTION_COMMAND = SUB_PATH_PROMOTION_COOMMAND + SUB_PATH_BUILD + SUB_PATH_BUILDER_SHELL_COMMAND; private static String CREATE_PROMOTION_JSON = "{'properties':{'stapler-class-bag':'true','hudson-plugins-promoted_builds-JobPropertyImpl':{'promotions':{'activeItems':{'name':'%s','isVisible':'','icon':'star-gold','hasAssignedLabel':false,'assignedLabelString':'','conditions':{'stapler-class-bag':'true'}}}}}}"; private static final String CONTENT_TYPE = "application/x-www-form-urlencoded";   public static void updatePromotionShell(Document jobConfigDocument, String jobName, JenkinsPromotionClient jenkinsPromotionClient, String promotionShell, String path) throws IOException, DocumentException { if (StringUtils.isBlank(promotionShell)) {  return; } String promotionName = getPromotionName(jobConfigDocument, path); Document document = jenkinsPromotionClient.getJobPromotionXml(jobName, promotionName); document.selectSingleNode(PATH_PROMOTION_COMMAND).setText(promotionShell); jenkinsPromotionClient.updateJob(jobName, promotionName, document.asXML()); }  public static void createPromotionShell(Document jobConfigDocument, String tmpJobName, String jobName, String promotionShell, String path, JenkinsPromotionClient jenkinsPromotionClient) throws IOException, DocumentException { if (StringUtils.isBlank(promotionShell)) {  return; } String promotionName = getPromotionName(jobConfigDocument, path); Document document = jenkinsPromotionClient.getJobPromotionXml(tmpJobName, promotionName); document.selectSingleNode(PATH_PROMOTION_COMMAND).setText(promotionShell); Map<String, String> map = Maps.newHashMap(); map.put("Content-Type", CONTENT_TYPE); map.put("json", String.format(CREATE_PROMOTION_JSON, promotionName)); try {  jenkinsPromotionClient.createJob(jobName, map); } catch (Exception e) {  log.error("初创promotion时失败" + e); } jenkinsPromotionClient.createJob(jobName, promotionName, document.asXML()); }  public static String getPromotionName(Document jobConfigDocument, String path) { return jobConfigDocument.selectSingleNode(path).getText(); }}

package cn.caijiajia.phoenix.service.jenkins;import com.offbytwo.jenkins.client.JenkinsHttpClient;import com.offbytwo.jenkins.client.util.EncodingUtils;import org.dom4j.Document;import org.dom4j.DocumentException;import org.dom4j.DocumentHelper;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Component;import java.io.IOException;import java.util.Map; /** * @author chenlang * date 2018/5/4 */@Componentpublic class JenkinsPromotionClient {  @Autowired private JenkinsHttpClient jenkinsHttpClient;  public JenkinsPromotionClient() { }  /** * 获取job的promotion配置文件 * * @param jobName job名称 * @param promotionName promotion名称 * @return * @throws IOException */ public Document getJobPromotionXml(String jobName, String promotionName) throws IOException, DocumentException { return DocumentHelper.parseText(this.getJobXml(jobName, promotionName)); }   /** * 更新job * * @param jobName * @param promotionName * @param jobXml * @throws IOException */ public void updateJob(String jobName, String promotionName, String jobXml) throws IOException { this.jenkinsHttpClient.post_xml(this.toJobBaseUrl(jobName, promotionName) + "/config.xml", jobXml, true); }  /** * 添加job脚本 * * @param jobName * @param jobXml * @throws IOException */ public void createJob(String jobName, String promotionName, String jobXml) throws IOException { this.jenkinsHttpClient.post_xml(this.toJobBaseUrl(jobName, promotionName) + "/config.xml", jobXml, true); }  /** * 添加promotion的job * * @param jobName * @param map * @throws IOException */ public void createJob(String jobName, Map map) throws IOException { this.jenkinsHttpClient.post_form("/job/" + EncodingUtils.encode(jobName) + "/configSubmit?", map, false); }  private String getJobXml(String jobName, String promotionName) throws IOException { return this.jenkinsHttpClient.get(this.toJobBaseUrl(jobName, promotionName) + "/config.xml"); }  private String toJobBaseUrl(String jobName, String promotionName) { return "/job/" + EncodingUtils.encode(jobName) + "/promotion/process/" + promotionName; }  /** * promotion脚本的构建 * @param jobName * @param promotionName * @param version * @param isFirstBuild * @throws IOException */ public void build(String jobName,String promotionName,Integer version,boolean isFirstBuild) throws IOException{ if (isFirstBuild) {  this.jenkinsHttpClient.post("/job/"+ EncodingUtils.encode(jobName) + "/"+version+"/promotion/forcePromotion?name="+promotionName+"&json=%7B%7D&Submit=Force promotion"); } else {  this.jenkinsHttpClient.post("/job/"+ EncodingUtils.encode(jobName) + "/"+version+"/promotion/"+promotionName+"/build?json=%7B%7D&Submit=Re-execute promotion"); } }}

其中的方法封装了对promote build插件中关于配置的增删改查，以及promotion脚本的构建
