Setting downloads directory for chrome driver suddenly stopped working after upgrade - selenium-webdriver

Question

After I've upgraded my project to use latest java selenium webdriver 3.7.1 and latest chrome driver 2.33 I noticed that my tests dealing with Excel export started to fail.
After debugging I see that for some reasons downloads directory is not being set to custom location and instead the default one is used. Nothing shows up in logs or whatsoever.
Any help appreciated.
Setting downloads directory is like usual:
val prefs = Map(
"profile.default_content_settings.popups" -> Integer.valueOf(0),
"download.default_directory" -> downloadsDir,
"credentials_enable_service" -> false,
"profile.password_manager_enabled" -> false
)
val chromeOptions:ChromeOptions = new ChromeOptions()
chromeOptions.setExperimentalOption("prefs", prefs)
val d = new ChromeDriver(chromeOptions)

Answer 1

I use WebDriver 3.7.1 and Chromedriver 2.33 and of course Chrome v.62 (try check Your Version of Chrome), and I can download files.
I'm using folder
public static String javaIoTmpDir = System.getProperty("java.io.tmpdir")+"/autotest/";
and I create/clean it with script in TestNG annotation: #BeforeSuite
File theDir = new File(javaIoTmpDir);
// if the directory does not exist, create it
if (!theDir.exists()) {
System.out.println("creating directory: " + theDir.getName());
boolean result = false;
try{
theDir.mkdir();
result = true;
}
catch(SecurityException se){
se.printStackTrace();
}
if(result) {
System.out.println(javaIoTmpDir+" created");
}
}
FileUtils.cleanDirectory(new File(javaIoTmpDir));
}
