I made a setup workspace.bat file with the command gradlew setupDecompWorkspace but when I try and run it, the cmd starts and then instantly closes. I am not good at this and I'm trying to learn but I have windows 8, 64 bit with 8g ram
That's how it's supposed to work. If you need it to stay up, either add a pause to the bat file or open the file using CMD (from inside of CMD by typing the full file path and name)
