我正在使用Jenkins Blue Ocean特性GitHub JenkinsFile。我在全局工具配置中定义了“JDK8”和“Maven 3.5.3”，选中了“autoinstall”。

这是我的JenkinsFile：

    pipeline {
      agent any
      stages {
        stage('Initialize') {
          steps {
            sh '''
               echo "PATH = ${PATH}"
               echo "M2_HOME = ${M2_HOME}"
               mvn --version 
               '''
          }
        }
        stage('Build') {
          steps {
            sh 'mvn -Dmaven.test.failure.ignore=true install'
          }
          post {
            success {
              junit 'target/surefire-reports/**/*.xml'
            }
          }
        }
      }
      tools {
        maven 'Maven 3.5.3'
        jdk 'jdk8'
      }
      post {
        always {
        deleteDir()
        }
      }
    }

您正在为系统运行一个错误版本的文件（这里是java）。

问题：文件在那里，无法执行。错误消息是“没有这样的文件或目录”

解决方案：您正在为您的系统运行错误的文件版本。

例如，如果您在带有Alpine Linux的Docker容器中运行Jenkins安装，就会出现问题，因为Alpine使用musl libc。Oracle Java二进制文件只在glibc上运行。
