Hi,

 

Haven't been here in a while and decided to try my hand at modding again, however, I've a quite the issue. Gradle is trying to use Java version 11.0.4 but after reading online, Forge does not support this yet. As such, I'm trying desperately hard to make sure that it uses Java 8, however, I'm coming up to a loss.

I'm getting the following issue:

My gradle version is 5.6.1 and the wrapper version is also 5.6.1.

My question is, how do I go about setting up gradle properly so that it can use the right java version so that I can start modding?

Did you install Java JDK and JRE 8? Is your JAVA_HOME path pointing to them? Have you uninstalled Java 11?
