Problems with excel table to DMN decision table converter

Hi!
I’m trying to use excel table to DMN table converter by executing command

java -jar dmn-xlsx-cli-0.2.0.jar --inputs A --outputs B "C:\xlsdmn\test2.xlsx" "C:\xlsdmn\test2.dmn"

But it throws an exception

PS C:\xlsdmn> java -jar dmn-xlsx-cli-0.2.0.jar --inputs A --outputs B "C:\xlsdmn\test2.xlsx" "C:\xlsdmn\test2.dmn"

Does anyone know what’s the problem with this?

I get the same error message. Do you have a solution for the problem in the meantime?

No, I haven’t
