eclipse如何在Java源代码中使用TikaCLI功能？

Question

我正在尝试使用Apache Tika从office文档中提取嵌入文件。使用Tika CLI（cmd），一切都运行良好。但我必须在Eclipse的Java源代码中集成它

所以我所做的是：

public static void saveEmbedds(String inputfile, String outputfile) throws Exception{
    try{
        String[] arguments = new String[]{"-z", "--extract-dir=" + removeExtension(outputfile), inputfile};
        System.out.println("Using TIKA CLI to dedect embedded Files. Target Directory: "+ removeExtension(outputfile));
        TikaCLI.main(arguments);
    }
    catch(Exception e){
        logger.info("Exception in saveEmbedds, during search in File: " + inputfile + "\r\nDetails: " + e);
    }

}

这实际上适用于每种文件类型，除了.pptx。当inputfile是一个。pptx文件，它会产生很多错误。使用cmd同样有效

有没有更好的方法来使用Apache Tika CLI的功能我还尝试了ExtractEmbeddedFiles的示例代码，但我没有为嵌入的.ppt文件工作
