尝试使用 Docx4J 转换为 PDF：没有虚拟方法 getModule（）Ljava/lang/Module

问：

我正在尝试使用 Docx4J 将 .docx 文件转换为 .pdf。我收到此错误：

FATAL EXCEPTION: main

这个确切的错误消息只在 Google 搜索上出现过一次，那里没有 Docx4J 的迹象。

法典：

String tag = "Docx4J Test";
try {
    WordprocessingMLPackage mlPackage = WordprocessingMLPackage.load(getFilesDir().toPath().resolve("template-default.docx").toFile());
    mlPackage.save(getFilesDir().toPath().resolve("result.docx").toFile());
    Log.d(tag, "SAVED");
    FileOutputStream outputStream = new FileOutputStream(getFilesDir().toPath().resolve("result.pdf").toFile());
    Docx4J.toPDF(mlPackage, outputStream);
    Log.d(tag, "SUCCESS");
} catch (Docx4JException | FileNotFoundException e) {
    Log.d(tag, "onCreate: ".concat(e.getMessage()));
}

我将这些依赖项添加到：app/build.gradle

implementation("org.docx4j:docx4j-JAXB-ReferenceImpl:8.3.3") {
    exclude group: "commons-logging"
}
implementation "com.fasterxml:aalto-xml:1.3.2"
implementation "javax.xml.stream:stax-api:1.0-2"
implementation files("libs/awt-bastardised-17v8.jar") // https://github.com/plutext/Docx4j4Android4/blob/master/app/libs/awt-bastardised-17v8.jar
implementation("org.docx4j:docx4j-export-fo:11.4.8") {
    exclude group: "org.apache.xmlgraphics"
}
implementation "org.glassfish.jaxb:jaxb-runtime:4.0.3"

更改为 MOXy 不起作用 - 同样的错误。我尝试降级，但出现不同的错误。jaxb-runtime

下面是完整的示例，因此您可以自己运行它： https://github.com/Volper212/docx4j-test

请记住，为了运行它，您需要在应用程序（）的目录中有一个文件。这可以是任何有效的 .docx 文件。template-default.docxfiles/data/user/0/com.example.docx4jtest/files/template-default.docx

为了达到这一点，我使用了以下资源：
