javadoc - java.lang.NoClassDefFoundError：org / docx4j / openpackaging / exceptions / Docx4JException

Question

我试图在源文件上运行（使用ANT）Javadoc以使用docx4j以表格格式生成文档（使用自定义doclet）（也尝试使用Apache POI，同样的错误）。我知道错误的原因（在运行时没有找到类）。运行ANT Build File后，我收到如下控制台错误。我不确定为什么会这样。

控制台错误

我已经扫描了StackOverflow这个问题，但找不到解决方案。

我使用了类似的代码：

public class Doc4jData {

public static void main (String a[]) throws  Exception
{

    WordprocessingMLPackage wordPackage = WordprocessingMLPackage.createPackage();
    MainDocumentPart mainDocumentPart = wordPackage.getMainDocumentPart();
    mainDocumentPart.addStyledParagraphOfText("Title", "Hello World!");
    mainDocumentPart.addParagraphOfText("Welcome Shashank");
    File exportFile = new File("welcome.docx");
    wordPackage.save(exportFile);
}

我使用了Spring Boot，只需确保使用依赖项即可：

<dependency>
        <groupId>org.docx4j</groupId>
        <artifactId>docx4j</artifactId>
        <version>3.3.5</version>
    </dependency>
    <dependency>
        <groupId>javax.xml.bind</groupId>
        <artifactId>jaxb-api</artifactId>
        <version>2.1</version>
    </dependency>

我能够成功生成一个名为“ welcome”的单词文件
