jenkins-rest 库是一个面向对象的 Java 项目,它通过编程方式提供对 Jenkins REST API 的访问,以访问 Jenkins 提供的一些远程 API。它使用 jclouds 工具包构建,可以轻松扩展以支持更多 REST 端点。其功能集不断发展,用户可以通过拉取请求贡献新的端点。在当前状态下,使用此库可以提交作业、跟踪其通过队列的进度并监控其执行直到完成,并获取构建状态。目前提供的服务包括:
- 端点定义(属性或环境变量)
- 身份验证(通过属性或环境变量进行基本和 API 令牌)
- Crumbs Issuer 支持(自动检测 crumbs)
- 文件夹支持
- 作业 API(构建、构建信息、带参数构建、配置、创建、删除、描述、禁用、启用、作业信息、最后构建编号、最后构建时间戳和渐进文本)
- 插件管理器 API(安装必要的插件、列出当前插件)
- 队列 API(取消、列出队列项、查询队列项)
- 统计 API(总体负载)
- 系统 API(系统信息)
引入依赖jar包
在工程pom.xml文件中引入如下配置,classifier
配置一定要加上:
<dependency><groupId>io.github.cdancy</groupId><artifactId>jenkins-rest</artifactId><version>1.0.2</version><classifier>all</classifier>
</dependency>
注意,jenkins-rest 要求至少 jdk11,可以在这里查看
使用代码示例
假设Jenkins地址是 http://192.168.56.114:8080
1、初始化客户端链接
private static JenkinsClient client;
private static final String JENKINS_URL = "http://192.168.56.114:8080";public static void init() {client = JenkinsClient.builder().endPoint(JENKINS_URL) // Jenkins地址.credentials("admin:admin123") // 账号密码..build();SystemInfo systemInfo = client.api().systemApi().systemInfo();log.info("jenkinsVersion: {}", systemInfo.jenkinsVersion());
}
2、查询任务列表
public static void jobs() {JobsApi jobsApi = client.api().jobsApi();JobList jobList = jobsApi.jobList("");jobList.jobs().forEach(job -> System.out.println(job.name()));
}
3、触发无参任务构建
返回的value不为null,代表执行成功
public static void build() {JobsApi jobsApi = client.api().jobsApi();// 必须是无参数任务String jobName = "job_no_params";IntegerResponse response = jobsApi.build("", jobName);System.out.println("build = " + response);// 返回的value不为null,代表执行成功if (response.value() != null) {System.out.println("任务执行成功:" + jobName);} else {System.out.println("任务执行失败:" + response.errors());}
}
4、触发有参任务构建
这里的任务必须是带参数的,如果调用的无参任务,会报错!
返回的value不为null,代表执行成功
public static void buildWithParameters() {JobsApi jobsApi = client.api().jobsApi();Map<String, List<String>> properties = new HashMap<>();properties.put("ENV", Collections.singletonList("prod"));// 必须是有参数任务String jobName = "job_with_params";IntegerResponse response = jobsApi.buildWithParameters("", jobName, properties);System.out.println("buildWithParameters = " + response);// 返回的value不为null,代表执行成功if (response.value() != null) {System.out.println("任务执行成功:" + jobName);} else {System.out.println("任务执行失败:" + response.errors());}
}
5、创建新任务
创任务必须传入xml配置数据
public static void createJob() {JobsApi jobsApi = client.api().jobsApi();String configXml = "<?xml version='1.1' encoding='UTF-8'?>\n" +"<flow-definition plugin=\"workflow-job@1385.vb_58b_86ea_fff1\">\n" +" <actions>\n" +" <org.jenkinsci.plugins.pipeline.modeldefinition.actions.DeclarativeJobAction plugin=\"pipeline-model-definition@2.2151.ve32c9d209a_3f\"/>\n" +" <org.jenkinsci.plugins.pipeline.modeldefinition.actions.DeclarativeJobPropertyTrackerAction plugin=\"pipeline-model-definition@2.2151.ve32c9d209a_3f\">\n" +" <jobProperties/>\n" +" <triggers/>\n" +" <parameters/>\n" +" <options/>\n" +" </org.jenkinsci.plugins.pipeline.modeldefinition.actions.DeclarativeJobPropertyTrackerAction>\n" +" </actions>\n" +" <description></description>\n" +" <keepDependencies>false</keepDependencies>\n" +" <properties/>\n" +" <definition class=\"org.jenkinsci.plugins.workflow.cps.CpsFlowDefinition\" plugin=\"workflow-cps@3826.v3b_5707fe44da_\">\n" +" <script>pipeline {\n" +" agent any\n" +" environment {\n" +" CC = 'clang'\n" +" }\n" +" stages {\n" +" stage('Example') {\n" +" environment {\n" +" DEBUG_FLAGS = '-g'\n" +" }\n" +" steps {\n" +" sh 'printenv'\n" +" }\n" +" }\n" +" }\n" +"}</script>\n" +" <sandbox>true</sandbox>\n" +" </definition>\n" +" <triggers/>\n" +" <disabled>false</disabled>\n" +"</flow-definition>\n";String newJobName = "java_api_02";RequestStatus status = jobsApi.create("", newJobName, configXml);if (status.value()) {System.out.println("任务创建成功: " + newJobName);} else {System.out.println("任务创建失败: " + newJobName);}
}
6、删除任务
public static void delete() {JobsApi jobsApi = client.api().jobsApi();String jobName = "api05";RequestStatus status = jobsApi.delete("", jobName);System.out.println("delete = " + status);if (status.value()){System.out.println("任务删除成功: " + jobName);}else{System.out.println("任务删除失败: " + status.errors());}
}
7、禁用/启用任务
public static void disable() {JobsApi jobsApi = client.api().jobsApi();boolean flag = jobsApi.disable("", "api01");System.out.println("disable = " + flag);
}public static void enable() {JobsApi jobsApi = client.api().jobsApi();boolean flag = jobsApi.enable("", "api01");System.out.println("enable = " + flag);
}
8、查询最近构建序号
public static void lastBuildNumber() {JobsApi jobsApi = client.api().jobsApi();String jobName = "job_no_params";Integer lastBuildNumber = jobsApi.lastBuildNumber("", jobName);System.out.println("lastBuildNumber = " + lastBuildNumber);
}
9、Jenkins服务负载情况查询
public static void overallLoad() {OverallLoad overallLoad = client.api().statisticsApi().overallLoad();System.out.println("overallLoad = " + overallLoad);
}
