I've come across --username and --password and have added them to the program arguments in runClient.launch but when I run the task they have no effect. Why is this?
I also wanted to ask where other people are learning about things such as --username and --password. I've read through most of the information at https://mcforge.readthedocs.io/en/stable/ and there was no mention of these arguments. Is there more documentation elsewhere, or have people just found out about things like this by looking at the source code? Essentially what I'm asking is what's the best way to learn more about making forge mods other than what's in the documentation?
