Jenkins Blue Ocean: Maven не видит Java

Я получаю сообщение об ошибке "/var/jenkins_home/tools/hudson.model.JDK/jdk8/bin/java: not found:", хотя путь существует:

Я использую функцию Jenkins Blue Ocean, GitHub Jenkinsfile. У меня есть "jdk8" и "Maven 3.5.3", определенные в Global Tool Configuration, "autoinstall" отмечен.

Вот мой 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()
        }
      }
    }
