如何使用 Groovy 从服务器上的给定路径读取文件名

Question

I have multiple files on the given FTP path. I want to read the latest file received, for which I need to read all the file names in the given path. I am using Groovy on the OUAF based product, ORMB. Please suggest on how to read the file names. Also, new File() statement is not supported.

Assuming you want to use apache commons.net module you can do this:

@Grab(group='commons-net', module='commons-net', version='3.7')
import org.apache.commons.net.ftp.FTPClient

String hostname = "some-server.some-domain.com"
String username = "someUser"
String password = "somePassword"
String path = "/var/some/path"

println("About to connect....");
new FTPClient().with {
    connect hostname
    enterLocalPassiveMode()
    login username, password
    changeWorkingDirectory path
    FTPFile latest = listFiles().max { it.timestamp.time }
    println("Downloading ${latest.name}..")
    File incomingFile = new File( latest.name )
    incomingFile.withOutputStream { os -> retrieveFile(latest, os) }
    disconnect()
}
println("...Done.");
