我正在使用Jenkins版本 2.7.1 ，我目前遇到与Sonar交谈的问题。 我们的企业Sonar目前版本 4.5.4 ，我们不允许更改此内容 在詹金斯，我使用的是Maven 3.3.9
我得到的错误如下

问题：有没有人知道我需要改变什么才能让它发挥作用？
就像一个FYI - 我在没有jenkins的情况下在本地试过 - 只是运行maven命令并得到同样的错误。
答案 0 :(得分：2)
由于正确追踪此问题所需的详细信息水平超出了您通过问题描述实际提供的内容，因此以下是一些可能的问题排查路径：
降级Sonar Maven插件：虽然official documentation声明：
来自maven-sonar-plugin 2.7 ，SonarQube＆lt; 4.5 不再受支持。 如果在 4.5 之前使用SonarQube实例，则应使用maven-sonar-plugin 2.6 。
因此，版本 4.5.4 确实应该由您当前使用的插件（org.sonarsource.scanner.maven:sonar-maven-plugin:3.0.2）支持，它可能是兼容性边缘情况，因此值得尝试更早一些版。但请注意，早期的主要版本为其groupId协调了不同的Maven（GAV，GroupId，ArtifactId，Version）：org.codehaus.mojo:sonar-maven-plugin:jar:2.7.1
检查代理设置：一个非常类似的错误（几乎相同的堆栈跟踪）已经reported，并且（未经证实的）结论是：
错误...表示您的代理可能已损坏响应。
请比较原始回复（不使用您的代理）和您从代理商处获得的回复。
