java调用jenkins-client实现添加任务

上篇文章，我们讲了一下通过jenkins-client连接jenkins,下来我们看看怎么添加任务以及中间遇到的问题。

我这边是用maven项目测试，通过git获取代码编译，最后查出来编译后的包

代码如下：

public static Boolean createJob(String jobName,String config) {
    boolean flag = false;

    //创建连接

    JenkinsServer jenkinsServer = JenkinsClient.getInstance().getConnection();
    try {
        jenkinsServer.createJob(jobName, config);
        jenkinsServer.close();
        flag = true;
    } catch (IOException e) {
        LOG.error("创建任务失败", e);
    }

    return flag;
}

其中，config的内容如下：

<?xml version='1.1' encoding='UTF-8'?>

xml属性具体我就不多说了，执行创建任务的程序后，报错如下：

org.apache.http.client.HttpResponseException: No valid crumb was included in the request

查看jenkins日志，如下：

六月 29, 2018 2:17:04 下午 hudson.security.csrf.CrumbFilter doFilter
警告: No valid crumb was included in request for /ajaxExecutors by admin. Returning 403.

解决方法：

原因是jenkins设置的安全策略，防止跨域攻击，去掉防止跨站点请求伪造，如下图：

测试如下：

public static void main(String[] args) {
    String str = FileUtils.readToStr("E:\\mywork\\devops-all\\src\\main\\resources\\config.xml");
    Boolean flag=createJob("xxxxuuuubbbb",str);
   System.out.println(flag);
}

然后登录到jenkins管理端，查看任务是否创建成功，如下：

OK了
