线程“主”java.lang.NoClassDefFoundError 中的异常：org/slf4j/LoggerFactory

Question

package photo;

import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;
import com.github.sarxos.webcam.Webcam;

public class capture {

    public static void main(String arg[]) throws IOException {
        Webcam webcam = Webcam.getDefault();
        webcam.open();
        BufferedImage image = webcam.getImage();
        ImageIO.write(image, "JPG", new File("test.jpg"));
    }

}

我已经编写了这个 java 代码来通过网络摄像头捕获照片，但是这个代码抛出了一个错误/异常，请告诉我该如何解决它。？

下载 SLF4J 并将 slf4j-api-1.7.2.jar 文件放到你的类路径中。
