"java.nio.Files#delete" should be preferred

When java.io.File#delete fails, this boolean method simply returns false with no indication of the cause. On the other hand, when java.nio.file.Files#delete fails, this void method returns one of a series of exception types to better indicate the cause of the failure. And since more information is generally better in a debugging situation, java.nio.file.Files#delete is the preferred option.

Noncompliant Code Example

public void cleanUp(Path path) {
  File file = new File(path);
  if (!file.delete()) {  // Noncompliant
    //...
  }
}

Compliant Solution

public void cleanUp(Path path) throws NoSuchFileException, DirectoryNotEmptyException, IOException {
  Files.delete(path);
}
