使用Java实现构建jenkins的多个job并返回构建结果示例

背景：

使用java实现jenkins构建很简单，但是如何确定什么时候job已经构建完成才是关键，而且要实现多个job并行构建。

分析：

我有一篇文章提到过使用java实现jenkins构建,但是获取的结果是最后一次构建的结果,不能实时获取构建结果.实时获取构建结果有个关键的点,在于他会根据构建的版本号获取当前版本号的结果,如果对应版本号的结果为空则证明还在构建过程中,按照这个思路我们就可以进行编码了.

1.判断指定构建版本号的job是否执行完;

2.根据是否构建完成获取构建结果;

/** * 判断指定的构建版本号是否执行完成 * * @param number * 构建版本号 * @param jobName * 构建名称 * @return true为构建完成，false为未构建完成 */public static boolean isFinished(int number, String jobName) {boolean isBuilding = false;if (number <= 0) {throw new IllegalArgumentException('jenkins build number must greater than 0!');}try {JobWithDetails job = jobs.get(jobName).details();// build 如果为空则证明正在构建，走else了Build buildByNumber = job.getBuildByNumber(number);if (null != buildByNumber) {BuildWithDetails details = buildByNumber.details();if (null != details) {isBuilding = details.isBuilding();} else {isBuilding = true;}} else {isBuilding = true;} return !isBuilding;} catch (Exception e) {e.printStackTrace();} finally {}return false;}

private static int nextNum = 0;private static JobWithDetails jobWithDetails = null;private static boolean flag = true;private static BuildResult buildResult = null; /** * 根据项目名称触发jenkins构建 * * @param paramJobName * 项目名称 * @return 构建结果:如果为null则表明项目名称在jenkins中没有匹配的job */public static BuildResult triggerJenkins(String paramJobName) {try {jobWithDetails = jobs.get(paramJobName).details();nextNum = jobWithDetails.getNextBuildNumber();jobWithDetails.build();System.out.println('正在构建……');while (flag) {jobWithDetails = jobs.get(paramJobName).details();if (isFinished(nextNum, paramJobName)) {flag = false;System.out.println('构建完成……');}Thread.sleep(2000);}buildResult = jobWithDetails.getLastBuild().details().getResult();return buildResult; } catch (IOException e) {e.printStackTrace();} catch (InterruptedException e) {e.printStackTrace();}}return buildResult;

补充知识：Java 对接Jenkins API操作（不需要勾选允许站点跨域访问）

最先的是jenkins的跨域问题 如果是一般学习直接关闭 在公司Java对接jenkins的话 还是不关闭

需要的maven 依赖

<dependency> <groupId>com.offbytwo.jenkins</groupId> <artifactId>jenkins-client</artifactId> <version>0.3.8</version></dependency>

JenkinsUtil 不用勾选跨域也可以访问

public class JenkinsUtils { private static final Logger LOGGER = LoggerFactory.getLogger(JenkinsUtils.class); private static String job_class='hudson.model.FreeStyleProject'; private static String folder_class= 'com.cloudbees.hudson.plugins.folder.Folder'; public static JenkinsServer getJenkinsServer(String userName, String password, String jenkinsUrl) { JenkinsHttpClient jenkinsHttpClient=null; JenkinsServer jenkinsServer=null; try{ jenkinsHttpClient = new JenkinsHttpClient(new URI(jenkinsUrl), userName, password); jenkinsServer = new JenkinsServer(jenkinsHttpClient); }catch (URISyntaxException ex){ LOGGER.info('JenkinsUtils :{}',ex.getMessage()); throw new ResourceCenterException(ResponseCodeEnum.SYSTEM_ERROR_MESSAGE); } return jenkinsServer; } ; public static Integer buildWithParams(HashMap<String, String> params,String jobName, JenkinsServer jenkinsServer) { JobWithDetails job=null; int nextBuildNumber =0; try{ job = jenkinsServer.getJob(jobName); /*根据名称获取job*/ if(null==job){ LOGGER.info('jenkins 不存在该Job ：{}',jobName); throw new ResourceCenterException(ResponseCodeEnum.JOB_NOT_EXIST); } /*获取下一次构建的构建编号，可以用于在触发构建前，先记录构建编号。在后续获取指定编号的构建结果*/ //这里需要 一个插件 Build With Parameters Plugin nextBuildNumber=job.getNextBuildNumber(); job.build(params,true); }catch (IOException ex){ LOGGER.info('JenkinsUtils :{}',ex.getMessage()); throw new ResourceCenterException(ResponseCodeEnum.SYSTEM_ERROR_MESSAGE); } //获取结果 如果为null表示正在构建中 SUCCESS 表示构建成功 return nextBuildNumber; } ; /** * 获取job 某一个构建的日志 * @param number * @param jobName * @param jenkinsServer * @return * @throws Exception */ public static String getBuildLogPrint(Integer number, String jobName, JenkinsServer jenkinsServer) { BuildWithDetails buildWithDetails=getBuildDetails(number,jobName,jenkinsServer); String log =null; try{ log=buildWithDetails.getConsoleOutputText(); }catch (IOException ex){ LOGGER.info('JenkinsUtils :{}',ex.getMessage()); throw new ResourceCenterException(ResponseCodeEnum.SYSTEM_ERROR_MESSAGE); } return log; } /** * 获取job 某一个构建的结果 ：成功，失败，取消等状态 * @param number * @param jobName * @param jenkinsServer * @return * @throws Exception */ public static String getBuildLogResult(Integer number, String jobName, JenkinsServer jenkinsServer) throws Exception { BuildWithDetails buildWithDetails=getBuildDetails(number,jobName,jenkinsServer); BuildResult result = buildWithDetails.getResult(); return result.name(); } private static BuildWithDetails getBuildDetails(Integer number, String jobName, JenkinsServer jenkinsServer){ JobWithDetails job = null; Build build=null; BuildWithDetails buildWithDetails=null; try{ job=jenkinsServer.getJob(jobName); /*根据jobName名称获取job*/ build = job.getBuildByNumber(number); buildWithDetails = build.details(); }catch (Exception e){ LOGGER.info('JenkinsUtils :{}',e.getMessage()); throw new ResourceCenterException(ResponseCodeEnum.SYSTEM_ERROR_MESSAGE); } return buildWithDetails; } //暂时解析一层文件夹 public static String getJobFullName(JenkinsServer jenkinsServer,String jobName){ String jobFullName=''; try { Map<String, Job> jobs1 = jenkinsServer.getJobs(); if(null!=jobs1.get(jobName)){return jobName; } Set<String> params = jobs1.keySet(); for (String tempKey: params) {jobFullName=tempKey;JobWithDetails job = jenkinsServer.getJob(tempKey);if(!folder_class.equals(job.get_class())){ continue;}Optional<FolderJob> folderJob = jenkinsServer.getFolderJob(job);FolderJob folderJob1 = folderJob.get();Map<String, Job> jobs = folderJob1.getJobs();Job targetJob = jobs.get(jobName);if(null!=targetJob){ jobFullName=jobFullName+'/'+jobName; return jobFullName;} } }catch (IOException ex){ LOGGER.info('JenkinsUtils :{}',ex.getMessage()); throw new ResourceCenterException(ResponseCodeEnum.SYSTEM_ERROR_MESSAGE); } return jobFullName; }}

为什么Java对接jenkins 不需要勾选跨域访问也可以：

job.build(params,true);

这个方法是带参数构建job true表示需要跨域访问 所以在代码底层为true时 会去

http://JENKINS_URL/crumbIssuer/api/xml

获取crumb 然后放进header里面 就可以了
