> I added archive properies based on the example provided in the official 7zip
> code and was able to decompress it properly using the 7zip tool, but when I
> decompress it using commons-compress I get the following error(The
> COMMPRESS-681.7z is in attachment):
> {code:java}
> code:
> SevenZFile.builder().setPath(Paths.get(("COMPRESS-681.7z"))).get();
> Below is the output I receive:
