我正在尝试将文件从本地目录上传到远程目录。我有一个为此编写的Groovy库。

def file = "$WORKPLACE/**/*-${BUILD_NUMBER}-*/file.txt"

pulic uploadArtifct (String user, String password, String file, String 
  location) {
  def cred = "${user}:${password}"
  def cmd = ["curl", "-v", "-u", cred, "-F", "files=@${file}", ${location}]
  try {
   def sout = new StringBuffer(), serr = new StringBuffer()
   def proc = cmd.execute()
   proc.consumeProcessOutput(sout, serr)
   proc.waitForOrKill(1000)
   println sout
  } catch (Exception e) {
    throw new RuntimeExceptipon("Cannot execute curl, exception: [${e.getClass().getName()} - '${e.getMessage()}']")
   }
  }

但是，以上操作失败并显示以下错误：

java.lang.RuntimeException: Cannot execute curl, exception: [java.lang.RuntimeException - 'Error running ; stdout='', stderr='warning:setting file 
Warning: /app/jenkins/workspace/Job/**/*-10-*/file.txt 
Warning: failed!

如何确保文件设置正确？也就是-F方法正确吗？
