so, basically, i'm trying to make a mod via Eclipse, so i downloaded "forge-1.20.1-47.2.1-mdk".
after decompiling* then opening it in the said IDE (Eclipse) and Running the project, i get this error.
shortened :
Exception in thread "main" com.electronwill.nightconfig.core.io.ParsingException: Invalid bare key: ${mod_id}
entire error : pastebin
i'm mostly new to forge, so yea.
