使用PDFBox获取java.lang.NoClassDefFoundError

我正试图从Eclipse中的java应用程序中读取带有PDFBox库的PDF文件。这是一个简单的PDF文本，但我得到一个异常java.lang.NoClassDefFoundError:org/apache/fontbox/FontBoxFont

我读过类似的文章，但这些解决方案对我不起作用。这是我的密码：

package pdfreader;

import java.io.*;
import org.apache.pdfbox.pdmodel.*;
import org.apache.pdfbox.text.*;

public class PdfReader {
private static void readPDF(String srcPDF) {
    try {
        PDDocument document = PDDocument.load(new File(srcPDF));
        if (!document.isEncrypted()) {
            PDFTextStripper stripper = new PDFTextStripper();
            String text;

            text = stripper.getText(document);

            System.out.println("Text:" + text);
        }
        document.close();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

public static void main(String[] args) {
    
    String srcPDF = "Test.pdf";

    readPDF(srcPDF);
    
}
}

追踪是：

我在Eclipse的Java构建路径中包含了commons-logging-1.1.jar和pdfbox-2.0.21.jar。

我在路径中添加了fontbox-2.0.21.jar解决了这个问题
