使用Java实现构建jenkins的多个job并返回构建结果示例
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;
}
http:// 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
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
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
if(null!=jobs1.get(jobName)){
return jobName;
}
Set
for (String tempKey: params) {
jobFullName=tempKey;
JobWithDetails job = jenkinsServer.getJob(tempKey);
if(!folder_class.equals(job.get_class())){
continue;
}
Optional
FolderJob folderJob1 = folderJob.get();
Map
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
