[1.12] Gradle major/minor version

[PegBeard]

I recently updated my JRE and JDK to 8u131 (see attached image). I had no problem with 1.11.2, but when trying to setup the workspace for 1.12 I get an unsupported major.minor version 52.0 error.
I know this means there is a version discrepancy, but I don't know which version of java I need.

Bytecode version 52.0 corresponds to Java 8.

I know that 52 is java 8, but that's what I have installed. I removed old versions when I updated the jre and jdk, so as far as I can tell, java 8 is the only version I have installed.
Do I have to change something on my system to make sure gradle is actually using java 8?

I forgot to change my environment variables. All sorted now.
