这段代码可以下载两个工件：

def target = params.BuildInfo.trim()

def downloadSpec = """{
  "files": [{
    "pattern": "${artifactory}.zip",
    "target": "./${target}.zip"
  }]
}"""

def buildInfo = server.download spec: downloadSpec
def files = findFiles(glob: "**/${target}.zip") // Define `files` here

if (files) { // And verify `it` here, so it'll wait 
...
}

就我个人而言，我最终以这种方式实现了Khoa的想法

try {
    // attempt to retreive the results from artifactory
    rtDownload (
      serverId: 'my_arti_server',
      spec: """{
        "files": [
          {
            "pattern": "somepath/run_*.zip",
            "target": "run/"
          }
        ]
      }""",
      failNoOp: false, // no failure if no file was found
    )

    // rtDownload is async, we have to wait for dl completion
    def count = 5
    while(count > 0) {
      sh script:"""#!/bin/bash +e
        chmod 777 run/run_*.zip
      """  
      def files = findFiles glob: "run/run_*.zip"
      if (files.length > 0 ){
        break
      }
      sleep(5)
      count--
    }
  } catch (Exception e) {
    echo 'Exception occurred: ' + e.toString() 
  }

  def files = findFiles glob: "run/run_*.zip"
  if (files.length == 0 ){
    error("files couldn't be found")
  }

这不是完美的，但它等待一些文件存在。如果你只有一个文件，它应该工作，但如果你有几个文件，它可能会继续只要一个文件下载。我还没有检查，但与此我假设：

• 一个文件可以找到一旦下载完成（没有文件大小经常改变）
• 所有文件都被下载“在同一时间”
