带有插件 RobotPublisher 的 Jenkinsfile 导致 java.lang.NullPointerException

Question

我安装了Jenkins Plugin（1.6.5版本）直接在Jenkins中发布Robot Framework的测试结果
机器人测试用例运行成功并创建了必要的文件。
但是如果我想将结果发布到 Jenkins，管道会抛出异常。

詹金斯文件

pipeline {
  agent any
  stages {
    stage("Run Robot") {
      steps {
        sh "robot --outputdir robot-results robot-test-cases"
        script {
          step([$class : 'RobotPublisher',
                outputPath : 'robot-results',
                outputFileName : "**/output.xml",
                reportFileName : '**/report.html',
                logFileName    : '**/log.html',
                disableArchiveOutput : false,
                passThreshold: 100.0,
                unstableThreshold: 90.0])
        }
      }
    }
  }
}

感谢您提供插件版本！

RobotPublisher 2.0.0 之前的版本似乎有一个错误，因为 otherFiles 参数（应该是可选的）是必需的，如果您省略它，则会出现此错误。

我会通过添加一个与您的任何实际文件都不匹配的 otherFiles 参数来解决这个问题，例如：

        otherFiles : '*.no_such_file',
