Jenkinsは実行可能ファイルを見つけることができません

Question

Jenkinsで簡単なMavenビルドを設定しようとしていますが、ビルドJenkinsを実行するとmaven実行ファイルが見つかりません。ここで

は私Jenkinsfileです：私は受けてい

node { 
    def rtMaven = Artifactory.newMavenBuild() 

    stage 'Clone sources' 
    git url: 'https://github.com/user/project.git' 

    stage 'Artifactory configuration' 
    rtMaven.tool = "Maven-3.5.0" 

    stage 'Maven build' 
    def buildInfo = rtMaven.run pom: 'project/pom.xml', goals: 'clean install' 
    } 

エラーはこれです：

JENKINS_HOMEディレクトリのhudson.tasks.Maven.xmlファイルを調べることもできます。 出力例：

bash-4.2$ cat /var/lib/jenkins/hudson.tasks.Maven.xml                                  
<?xml version='1.0' encoding='UTF-8'?>                                     
<hudson.tasks.Maven_-DescriptorImpl>                                      
    <installations>                                           
    <hudson.tasks.Maven_-MavenInstallation>                                    
     <name>maven</name>                                         
     <properties>

      <installers>
