IllegalStateException when converting from docx to pdf via documents4j

Question

(SOLVED) I want to convert a docx-document into pdf. As the results with xdocreport weren't quite statisfactory, I tried out documents4j. Unfortunalty, I recieve the following IllegalStateException:

java.lang.IllegalStateException: class com.documents4j.conversion.msoffice.MicrosoftWordBridge could not be created by a (File, long, TimeUnit) constructor

My first guess would be that it put one extra pair of quotation marks around the path (cmd, /S, /C, ""F:\word_start199932774.vbs""). Is there anything I can do about that or is there something else I do wrong?

Any help is welcome, thanks a lot in advance.

UPDATE:

I found my mistake, instead of this line:

IConverter converter = LocalConverter.builder().baseFolder(new File("")).workerPool(20, 25, 1, TimeUnit.SECONDS).processTimeout(5, TimeUnit.SECONDS).build();

I need to use this line:

IConverter converter = LocalConverter.builder().baseFolder(base).workerPool(20, 25, 1, TimeUnit.SECONDS).processTimeout(5, TimeUnit.SECONDS).build();

with base being a temporary directory. My bad.

Please do not edit the resolution into the question but create an own answer for it which you can accept some time later. This allows the system to recognize the question as solved. — mkl, May 04 '17 at 16:22
such error could occur when you trying to make the conversion on Unix machine. Be aware, the lib requires MS components to be installed. https://github.com/documents4j/documents4j/issues/41 — Serhii Povísenko, Jun 17 '20 at 15:59
indeed, as @SerhiiPovísenko said, this library is not working in unix based systems(facepalm!). — brebDev, Dec 08 '21 at 12:00
@brebDev mate I advise you to use Gotenberg then. It will save you a lot of time https://stackoverflow.com/a/62434880/2852528 — Serhii Povísenko, Dec 08 '21 at 17:12
