我按照本页中给出的示例从JFrog artifactory下载工件：https://www.jfrog.com/confluence/display/JFROG/Scripted+Pipeline+Syntax#ScriptedPipelineSyntax-UploadingandDownloadingFiles
但是我一直收到NullPointerException。下面是脚本输出和错误：

[Pipeline] echo
download spec {
    "files": [
        {
            "pattern": "aod-libs-release/path-to-artifact/deployment/DM-DP-V3A.24-RELEASE/deployment-DM-DP-V3A.24-RELEASE.zip",
            "target": "./artifacts"
        }, {
            "pattern": "aod-libs-release/path-to-artifact/dm-auth-web-services/DM-AU-V3A.88-RELEASE/dm-auth-web-services-DM-AU-V3A.88-RELEASE.war",
            "target": "./artifacts"
        }
    ]
}
[Pipeline] echo

下面是我的Jenkins管道脚本

def artifactoryServer = Artifactory.server("Artifactory-instance-id")
artifactoryServer.connection.timeout = 300
def artifactDownloadSpec = """{
    "files": [
        {
            "pattern": "aod-libs-release/path-to-artifact/deployment/${env.DP_VERSION}/deployment-${env.DP_VERSION}.zip",
            "target": "./artifacts"
        }, {
            "pattern": "aod-libs-release/path-to-artifact/dm-auth-web-services/${env.VERSION}/dm-auth-web-services-${env.VERSION}.war",
            "target": "./artifacts"
        }
    ]
}"""

echo "download spec " + artifactDownloadSpec
echo "artifactory server " + artifactoryServer
artifactoryServer.download spec: artifactDownloadSpec

我在谷歌上搜索了GenericDownloadExecutor.java，找到了下面的代码，但无法找出我缺少的第52行所需的内容。看起来像是一个字段没有设置。

运行artifactoryServer.download步骤需要使用代理。例如：

- Jenkins编写的销售管道**

node {
  ...
  artifactoryServer.download spec: artifactDownloadSpec
  ...
}

- Jenkins申报管道**

但是，如果您仍然希望使用artifactoryServer.download，建议使用rtDownload步骤：

pipeline {
    agent any // <- Make sure there is an active agent
    stages {
        stage('Example') {
            steps {
                script {
                  ...
                  artifactoryServer.download spec: artifactDownloadSpec
                  ...
                }
            }
        }
    }
}
