基本Jenkins管道失败

Question

我在Openshift上运行了Jenkins 1.6。我正在尝试构建一个简单的Jenkins管道，它是从Git存储库构建的：

node {
  git url: 'https://github.com/fmarchioni/kitchensink-example.git'
  def mvnHome = tool 'M3'
  sh "${mvnHome}/bin/mvn clean install"
}

当我尝试构建管道时，它失败并显示不明确的消息：

你知道可能出现什么问题吗？ 感谢

Answer 1

我怀疑特定的shell脚本mvn clean install是错误的。如果可以，请尝试通过SSH连接到盒式磁带并直接尝试该Mavin命令。您可以添加调试选项（来自https://books.sonatype.com/mvnref-book/reference/running-sect-options.html）并希望看到一些更有用的输出！

尝试使用withMaven步骤括起命令。这将允许maven工具版本和JDK的规范，以及其他配置选项。

  withMaven(jdk: '<JDK name>', maven: '<maven name>') {
  sh 'mvn clean install'
  }

它还将记录build.log中的配置：

[Pipeline] withMaven
[withMaven] Options: []
[withMaven] Available options: 
[withMaven] use JDK installation <JDK name>
[withMaven] use Maven installation '<maven name>'
[Pipeline] sh
[workspace] Running shell script

您可能希望查看使用Pipeline Syntax链接。它可以生成可用于单个步骤的片段。它将显示withMaven步骤可用的选项。
