docker - 为什么我的bash函数在Jenkinsfile中不起作用

Question

我写这个功能

def docker_images(image_name,image_tag){

def curl_image_exists_status_code =

    curl_image_exists_status_code=sh (
    script:""" docker login -u XXXXX -p $$$$$$  2> /dev/null 1>/dev/null
    docker pull XXXXX/'${image_name}':'${image_tag}' > /dev/null && echo "success" || echo 'failed' 
    """,  returnStdout: true)
    echo "${curl_image_exists_status_code}"
    return (curl_image_exists_status_code == 'success')?true: false
    }

但输出是

success

null

最后一行返回 false curl_image_exists_status_code的输出应为成功，最后一行应返回true
但是为什么它不起作用？

尝试

def docker_images(image_name,image_tag){

def curl_image_exists_status_code=sh (
    script:""" docker login -u XXXXX -p $$$$$$  2> /dev/null 1>/dev/null
    docker pull XXXXX/'${image_name}':'${image_tag}' > /dev/null && echo "success" || echo 'failed' 
    """,  returnStdout: true)
    echo "${curl_image_exists_status_code}"
    return (curl_image_exists_status_code == 'success')?true: false
    }
