使用Netbeans 8.0.2，并希望使用org.apache.commons.io.FileUtils； 怎么样？

Question

Specifically I want to use the FileUtils.contentEquals(file1, file2) method.

I've downloaded and extracted files to C:\\Users\\Dov\\commons-io-2.4-bin\\commons-io-2.4 .

I added exactly that pathname to my Netbeans project Librairies folder but of course import org.apache.commons.io.FileUtils; didn't compile.

What will make the program below compile?

import java.io.File;
import java.io.IOException;
import static org.apache.commons.io.FileUtils.contentEquals;

public class CompareFileContents {

    public static void main(String[] args) throws IOException {

        File file1 = new File("C:\\Users\\Dov\\Docs\\desktop.ini");
        File file2 = new File("C:\\Users\\Dov\\Documents\\desktop.ini");

        System.out.println("test1.txt and test2.txt are the same: " +
                           contentEquals(file1, file2));
    }
}
