【问题描述】：

我的 github 存储库中有一个简单的 java 代码（只是一个 .java 文件，而不是项目），我想尝试使用 Jenkins 管道运行它。使用 freestyle 项目并将 git repo 链接到它时非常简单（只有两个命令：javac file.java 和 java file）并且它完美地工作。但是我尝试在管道中做同样的事情，它似乎不起作用。这是我为管道编写的脚本（我是 Jenkins 的新手）。有人可以指导我吗？

pipeline {
    agent any

    stages {
        stage('Build') {
            steps {
                javac BubbleSort.java
            }
        }
        stage('Run') {
            steps {
                java BubbleSort
            }
        }
    }
}

这是我得到的控制台日志输出：

[Pipeline] Start of Pipeline
[Pipeline] node
Running on Jenkins in /var/lib/jenkins/workspace/java
[Pipeline] {
[Pipeline] stage
[Pipeline] { (Build)
[Pipeline] }
[Pipeline] // stage
[Pipeline] stage
[Pipeline] { (Run)
Stage "Run" skipped due to earlier failure(s)
[Pipeline] }
[Pipeline] // stage
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline

我做了什么：在常规选项卡下，在“Github 项目”中，我添加了我的 github 存储库链接。

【问题讨论】：

  • 您能分享您在控制台日志中遇到的错误吗？
  • @PamelaSarkisyan 我在我的问题中添加了相同的内容
  • sh ("java BubbleSort")
  • Running on Jenkins in /var/lib/jenkins/workspace/java BubbleSort.java 文件是否位于此路径中？
  • @PamelaSarkisyan 不，java 文件在我的 Github 仓库中

标签： java jenkins jenkins-pipeline


【解决方案1】：

假设您已经从 Github 签出了您的代码，请尝试使用“sh”块在 shell 中运行您的命令：

pipeline {
    agent any

    stages {
        stage('Build') {
            steps {
                sh 'javac BubbleSort.java'
            }
        }
        stage('Run') {
            steps {
                sh 'java BubbleSort'
            }
        }
    }
}

【讨论】：

  • 你能告诉我你通过查看 Github 代码是什么意思吗？我已经在 J​​enkins 管道表单中的任何需要的地方添加了指向我的 repo 的链接，但构建仍然失败:(
  • 由于您没有在管道代码中声明“checkout scm”步骤，我想您在 Jenkins UI 中配置管道作业期间指定了您的存储库对吗？你试过我的建议了吗？它是否仍然因相同的错误而失败？
  • 是的，我在 UI 中添加了 github repo 链接。我试过你的建议，它仍然失败:(
  • 你能提供更多关于它是如何失败的信息吗？ （日志）在您尝试了我建议的答案后，它至少应该会因其他错误而失败。
