Unrecognized option: -Xincgc

[darkluffi]

I just installed forge and opened it on eclipse, but I always get this error when I try to run it. (I did not edit anything in the code) . I couldn't find anything about this topic, please help, I don't know what to do

You're probably using Java 9, where -Xincgc has been removed.

 

Also, FML doesn't work with Java 9 (yet), so you'll have to downgrade to Java 8 anyway.

Should I change path and that stuff to Java 8? Or is there an option in eclipse to do that? I have my other non minecraft projects compiled in java 9 since thats the sdk I downloaded

I haven't used Eclipse in a few years, so I don't know if there's an option for that. I'd imagine there is, but then again, it's Eclipse...

first Eclipse itself needs java 11 to run,
second this Thread is 4 years old
third if you have the same problem create your own thread and post more details
