Maven目录：权限被拒绝

Question

我已经在我的 linux 服务器中安装了 Maven 和 Jenkins。 Maven 从 putty 执行得非常好。但是，当我尝试使用 maven 运行管道作业时，从 Jenkins 收到以下错误：/data1/SOA/app/oracle/product/middleware/Oracle_Home/oracle_common/modules/org.apache.maven_3.2.5/bin/ mvn : 权限被拒绝

管道代码如下：

node {
   def mvnHome
   stage('Preparation') { 
      git branch: 'master', url: "http://UN:PW@IP/root/Test-Repo.git", credentialsId: 'QPGitCred'      
      mvnHome = tool 'org.apache.maven_3.2.5'
   }
   stage('Build') {
      if (isUnix()) {
         sh "'${mvnHome}/bin/mvn' --version"
      } else {
         bat(/"${mvnHome}\bin\mvn" --version/)
      }
   }
}

控制台输出：

我从 putty 使用以下命令检查了权限：

ls -l /data1/SOA/app/oracle/product/middleware/Oracle_Home/oracle_common/modules/org.apache.maven_3.2.5/bin/mvn

-rwxrwxrwx 1 testusr dba 5543 Dec 14  2014 /data1/SOA/app/oracle/product/middleware/Oracle_Home/oracle_common/modules/org.apache.maven_3.2.5/bin/mvn

这里的权限表明它有权执行这个文件。但仍然来自 Jenkins，我收到 Permission denied 错误。

感谢您提前回复。

感谢您的所有回复。

我可以通过将 Jenkins 配置为 root 用户来解决这个问题。我按照此链接中给出的步骤操作：Run shell command in jenkins as root user?

以下流程适用于 CentOS：

1. 打开这个脚本（使用 VIM 或其他编辑器）：

   vim /etc/sysconfig/jenkins

2. 找到这个 $JENKINS_USER 并更改为“root”：

   $JENKINS_USER="root"

3. 然后更改 Jenkins 主页、webroot 和日志的所有权：

   chown -R root:root /var/lib/jenkins chown -R root:root /var/cache/jenkins chown -R root:root /var/log/jenkins

添加 bash 命令以打印mvn 的当前用户/组和文件权限，如下所示。 此类信息有助于确认用户/组和文件权限是否符合预期。

stage('Build') {
  if (isUnix()) {
     sh """
       # print current user, group
       id

       # print folder's user group/access
       ls -l "${mvnHome}"/..
       ls -l "${mvnHome}"

       "${mvnHome}"/bin/mvn --version
     """
  } else {
     bat(/"${mvnHome}\bin\mvn" --version/)
  }
}
