Java Error: please install JCE Unlimited Strength Jurisdic tion Policy files

I am working on this Java application which needs to have access to "JCE Unlimited Strength" files and I DO HAVE installed them and it works properly when I build the solution (in Intellij) BUT when I make a jar output, for some reason it gives me this annoying error:

C:UsershwhateveroutartifactsAccepter_jar>java -cp Accepter.jar Main
org.apache.poi.EncryptedDocumentException: Export Restrictions in place - please install JCE Unlimited Strength Jurisdic
tion Policy files

any idea what is the problem?
