我正在尝试使用jenkins将我的项目部署到tomcat服务器，我正在使用脚本管道。我已经安装了部署到容器插件。我添加的用户是tomcat-users.xml

<role rolename="manager-script"/>
   <role rolename="manager-gui"/>
   <user username="deployer" password="deployer" roles="manager-script,manager-gui"/>

这是我编写的groovy脚本的一部分

stage('Deploy')
    {
        steps{
            deploy adapters: [tomcat8(credentialsId:'deployer', path: '', url: 'http://localhost:8080/')], contextPath: 'hr_login', onFailure: false, war: '**/*.war'
            echo "Project deployed";
        }
    }

但该项目尚未部署。堆栈跟踪如下所示：
