我在docker中运行Jenkins 2.345作为容器。主机操作系统是ubuntu 20.04 LTS。现在，我想编译一个需要Java 17的maven项目，为此我在Jenkins中安装了***JDK 17作为工具***。现在，为了验证新的JDK是否工作，我运行以下管道。
管道脚本

pipeline 
{
    agent any

    tools
    {
        jdk 'openjdk-17.0.5'
        maven 'maven'
    }

    stages {
        stage('Example') {
            steps {
                sh '''
                    env | grep -e PATH -e JAVA_HOME
                    which java
                    java -version
                    mvn -v
                '''
            }
        }
    }
}

构建管道后，我得到了以下输出日志。

+ grep -e PATH -e JAVA_HOME
+ env

+ mvn -v
The JAVA_HOME environment variable is not defined correctly,
this environment variable is needed to run this program.

因此，即使更新了JAVA_HOME值，Jenkins仍只能识别***/opt/java/openjdk/bin***中的*java，这是默认设置。
那么，有人能确定Jenkins出了什么问题，为什么会出现这个问题吗？
