背景：

使用java實現jenkins構建很簡單，但是如何確定什么時候job已經構建完成才是關鍵，而且要實現多個job并行構建。

分析：

我有一篇文章提到過使用java實現jenkins構建,但是獲取的結果是最后一次構建的結果,不能實時獲取構建結果.實時獲取構建結果有個關鍵的點,在于他會根據構建的版本號獲取當前版本號的結果,如果對應版本號的結果為空則證明還在構建過程中,按照這個思路我們就可以進行編碼了.

1.判斷指定構建版本號的job是否執行完;

2.根據是否構建完成獲取構建結果;

/** * 判斷指定的構建版本號是否執行完成 * * @param number * 構建版本號 * @param jobName * 構建名稱 * @return true為構建完成，false為未構建完成 */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 如果為空則證明正在構建，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; /** * 根據項目名稱觸發jenkins構建 * * @param paramJobName * 項目名稱 * @return 構建結果:如果為null則表明項目名稱在jenkins中沒有匹配的job */public static BuildResult triggerJenkins(String paramJobName) {try {jobWithDetails = jobs.get(paramJobName).details();nextNum = jobWithDetails.getNextBuildNumber();jobWithDetails.build();System.out.println('正在構建……');while (flag) {jobWithDetails = jobs.get(paramJobName).details();if (isFinished(nextNum, paramJobName)) {flag = false;System.out.println('構建完成……');}Thread.sleep(2000);}buildResult = jobWithDetails.getLastBuild().details().getResult();return buildResult; } catch (IOException e) {e.printStackTrace();} catch (InterruptedException e) {e.printStackTrace();}}return buildResult;

補充知識：Java 對接Jenkins API操作（不需要勾選允許站點跨域訪問）

最先的是jenkins的跨域問題 如果是一般學習直接關閉 在公司Java對接jenkins的話 還是不關閉

需要的maven 依賴

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

JenkinsUtil 不用勾選跨域也可以訪問

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); /*根據名稱獲取job*/ if(null==job){ LOGGER.info('jenkins 不存在該Job ：{}',jobName); throw new ResourceCenterException(ResponseCodeEnum.JOB_NOT_EXIST); } /*獲取下一次構建的構建編號，可以用于在觸發構建前，先記錄構建編號。在后續獲取指定編號的構建結果*/ //這里需要 一個插件 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); } //獲取結果 如果為null表示正在構建中 SUCCESS 表示構建成功 return nextBuildNumber; } ; /** * 獲取job 某一個構建的日志 * @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; } /** * 獲取job 某一個構建的結果 ：成功，失敗，取消等狀態 * @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); /*根據jobName名稱獲取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; } //暫時解析一層文件夾 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; }}

為什么Java對接jenkins 不需要勾選跨域訪問也可以：

job.build(params,true);

這個方法是帶參數構建job true表示需要跨域訪問 所以在代碼底層為true時 會去

http://JENKINS_URL/crumbIssuer/api/xml

獲取crumb 然后放進header里面 就可以了

以上這篇使用Java實現構建jenkins的多個job并返回構建結果示例就是小編分享給大家的全部內容了，希望能給大家一個參考，也希望大家多多支持好吧啦網。
