Java libreofficesdk引导程序

我将标准jar文件+juh-2.4.1.jar和ridl-3.2.1.jar（导入时出错）作为项目中的参考库。当我从中得到一段示例代码时，我总是遇到以下错误：

Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/star/comp/loader/JavaLoader

引导上始终存在NoClassDefFoundError。。正在搜索，但找不到太多。。有人知道如何解决这个问题吗？

在我的LibreOffice安装中，缺少的类位于文件jurt.jar中！现在继续调试
