regardless of which command I'm running I'll receive this error message:

can anybody tell me what I'm doing wrong? (tried multiple tutorials found here ...)

I will paste here my old message with instructions. It MUST work.

 

Create new folder anywhere, extract forge src to this folder, and run gradlew.bat with command setupDevWorkspace (create bat file with string "gradlew.bat setupDevWorkspace" and launch it), then run gradlew.bat with command eclipse (bat with "gradlew.bat eclipse"). After all  start Eclipse and make folder "Your-Forge-Src-Folder/eclipse" eclipse workspace. The End. =)

done exactly that (except run "gradlew setupDevWorkspace" in shell instead of from a bash file I'm on a Mac OS, so Darwin Unix, thus running the gradlew file instead of the gradlew.bat).

and after running "gradlew setupDevWorkspace" I received the above error message ...

Sorry, mac isn't my system, I don't know what to do in this way. An error says that problem with natives so I think that problem in Java(Try to reinstall it) or internet (maybe he couldn't download natives)

Known, you need to force macs to use 2.9.0, instructions somewhere in the repo issues.
