   ​options.setExperimentalOption("prefs", chromePrefs);
   ​if (platform.startsWith("local")) {
       ​options.addArguments("--start-maximized");

Solution:

Just make sharefolder on machine where running selenium node or where have access to and set properties for downloadpath on network path

String downloadFilepath = "\\localhost\folderfordownload";
​chromePrefs.put("download.default_directory", downloadFilepath);
