groovy – 输出我的Job正在运行的Jenkins作业的控制台文本

发布时间：2020-12-14 16:24:39 所属栏目：大数据 来源：网络整理
导读：我试着寻找 here和 here和 here. 我正在使用dsl流程.而且我希望能够看到控制台日志打印出我正在运行的工作中正在构建的工作.我试着四处寻找例子,我似乎无法找到我想要的东西.如果这个问题没有使用正确的术语,或者以不同的方式询问,我道歉.我只是想找到如何做
我试着寻找 here和 here和 here.

我正在使用dsl流程.而且我希望能够看到控制台日志打印出我正在运行的工作中正在构建的工作.我试着四处寻找例子,我似乎无法找到我想要的东西.如果这个问题没有使用正确的术语,或者以不同的方式询问,我道歉.我只是想找到如何做到这一点的答案.

A = build("Main Suites",SUITE: "qa_smoketests",OS: "mac")

下面我尝试这样做但它似乎没有用

OUTPUT = A.build.doConsoleText()
out.println(OUTPUT)

更新：

我尝试了第二种方法来动态更新它,我不断收到网址的问题？奇怪的是,如果我点击错误中的url链接,它会将我带到相应的页面.我确实需要修改事情b / c作业名称中有空格.我还编辑了这篇文章的错误日志来说MYHOSTURL而不是我真正的Jenkins主机网址.

更新2：

所以我能够通过修改responseFrom函数来处理需要身份验证的页面来获得第一个方法.

InputStream responseFrom(String url)
  {
  // See Using java.net.URLConnection to fire and handle HTTP requests 
  //     https://stackoverflow.com/a/2793153/1744774
  URL myURL = new URL(url);
  HttpURLConnection connection = (HttpURLConnection)myURL.openConnection();
  String userCredentials = "username:password";
  String encoding = new sun.misc.BASE64Encoder().encode(userCredentials.getBytes());
  String basicAuth = "Basic " + encoding;
  connection.setRequestProperty("Authorization",basicAuth);
  connection.setRequestProperty("Accept-Charset",StandardCharsets.UTF_8.name());
  return connection.getInputStream();  
  }

但是我仍然遇到让第二种方法起作用的问题.我想这是用于从下游作业获取内部版本号的函数.

java.util.concurrent.ExecutionException:
org.codehaus.groovy.runtime.InvokerInvocationException:
groovy.lang.MissingMethodException: No signature of method: static
java.lang.Integer.parseUnsignedInt() is applicable for argument types:
(java.lang.String) values: [164]

解决方法

有趣的问题.我无法理解这一点.

>您的第一个链接描述了您应该如何做到：通过“重复GET请求”.
>第二个是根据下游作业控制台输出的内容设置上游作业的结果.除了解析控制台输出之外,这可以通过其他方式实现.
>第三个是相反的方向：将输出从上游作业传递到下游作业.

我将尝试第一个,然后相应地更新这个答案.

下游构建完成后,以下内容将更新上游的日志.
