我是Jenkins的初学者。我不知道哪个语法会出错。
请推荐Groovy语法检查工具，它们可以帮助您解决问题或解决问题

//我的Jenkinsfile

podTemplate(label: 'hello',
    containers: [
        containerTemplate(
        name: 'git',
        image: 'alpine/git',
        ttyEnabled: true,
        command: 'cat'
        ),
        containerTemplate(
        name: 'docker',
        image: 'docker:latest',
        ttyEnabled: true,
        command: 'cat'
        ),
    ],
    volumes: [
        hostPathVolume(mountPath: '/var/run/docker.sock', hostPath: '/var/run/docker.sock'),
    ]
) {
    node('hello') {
        def appImage
        def hubCred = docker-hub-token

        stage('Checkout') {
            container('git') {

                script {
                    appImage = docker.build yeawonkim/momssi
                }
