我的测试作为Maven项目运行良好，它从Git中获取代码。
我想在管道中执行相同的操作，所以我为管道项目编写了以下脚本。

pipeline {
    agent any
    options {
        timestamps()
    }
    stages{ 
        stage('Just Testing') {
            steps {
                git "https://github.com/myRepo.git"
                script{
                        sh 'mvn test'
                }
                step([$class : 'Publisher', reportFilenamePattern : "**/testng-results.xml"])
            }
        }
    }   
}

但是当我执行时，我得到mvn：未找到命令错误全局工具配置中正确设置了Java和Maven路径（我可以肯定，因为我能够执行其他Maven项目，只有pipeline失败。）
控制台输出：
