scala “error: io error while decoding” “with utf-8”

Question

this thing keeps coming up I checked that all my source files are utf8 encoded, and Im using \'-encoding UTF8\' flag with both scalac and scala command line tools
any ideas?

Answer 1

This will be rare, however in my case this happened because I had a few files that had file ownership set to the company I am consulting at. This not the normal file ownership under security but the microsoft azure protection encryption that you can disable using right click -> File ownership -> Personal (if there is a business domain set there, it is encrypted and needs to be decoded). Windows apps can open the file normally but using non-ms tools, like winrar and seemingly this case, it could not decode the file. Ideally there should be a way to work with the encrypted files but I'm not going to spend time on that here! :)
