java - How to use FileUtils IO correctly?

Question

I tried to use method (credits to Shenyuan Lu ):

org.apache.commons.io.FileUtils.copyURLToFile(URL, File)

Precisely:

org.apache.commons.io.FileUtils.copyURLToFile(driver.getCurrentUrl(), "C:\Users\myDocs\myfoldermyFile.pdf");

However,Eclipse is underlining the copyURLToFile and suggesting to use copyFile. When I switch to copyFile, it suggests to use copyURLToFile again???

Answer 1

According to the FileUtils#copyURLToFile() API...

The first parameter needs to be a URL object, and the second parameter needs to be a File Object. You are passing Strings as both args. Try...

org.apache.commons.io.FileUtils.copyURLToFile(new URL(driver.getCurrentUrl()), new File("C:\Users\myDocs\myfolder\myFile.pdf"));

Also, since this method throws an exception, you either need to make your method throw an exception, or surround the statement in a try {} catch{} block.

e.g.

try {
    org.apache.commons.io.FileUtils.copyURLToFile(new URL(driver.getCurrentUrl()), new File("C:\Users\myDocs\myfolder\myFile.pdf"));
} catch (Exception x) { x.printStackTrace(); }
