Playing Sound From .jar File

Question

I have looked at countless different StackOverflow answers as well as answers from other sites, but none of the solutions have fixed my problem. I cannot for the life of me get my .wav file to play.

Here is my code:

Sound class:

public class Sound {
/**
 * Static file paths for each sound.
 */
public static String stepSound = "/resources/step.wav";

/**
 * Audio input stream for this sound.
 */
private AudioInputStream audioInputStream;

/**
 * Audio clip for this sound.
 */
private Clip clip;

/* -- Constructor -- */

/**
 * Creates a new sound at the specified file path.
 * 
 * @param   path    File path to sound file
 */
public Sound(String path) {
    // Get the audio from the file
    try {
        // Convert the file path string to a URL
        URL sound = getClass().getResource(path);
        System.out.println(sound);

        // Get audio input stream from the file
        audioInputStream = AudioSystem.getAudioInputStream(sound);

        // Get clip resource
        clip = AudioSystem.getClip();

        // Open clip from audio input stream
        clip.open(audioInputStream);
    } catch (UnsupportedAudioFileException | IOException | LineUnavailableException e) {
        e.printStackTrace();
    }
}

/* -- Method -- */

/**
 * Play the sound.
 */
public void play() {
    // Stop clip if it's already running
    if (clip.isRunning())
        stop();

    // Rewind clip to beginning
    clip.setFramePosition(0);

    // Play clip
    clip.start();
}

/**
 * Stop the sound.
 */
public void stop() {
    clip.stop();
}
}

Constructor call that leads to error:

// Play step sound
new Sound(Sound.stepSound).play();

I know this isn't the first time a problem like this has been asked or answered on this website, but I've been trying other solutions for hours at this point and all I've found is pain and frustration. I can post more code if needed. Thanks in advance.

EDIT: I have unpacked the .jar file and confirmed that the file is indeed there. The problem is that the URL ends up being null, and so a NullPointerException is thrown.

EDIT #2: Added more code in case there's another problem.
