As the topic description says: I was importing an existing gradle so I could start work on a 1.12.2 Minecraft mod and I got this error which I can't figure out how to fix.

I simply downloaded the Mod Development Kit from the official Minecraft Forge site and went to import the project folder with the extracted development kit in it into eclipse and after a bit of loading I got this error.

If it helps I also got these errors: 
The import net cannot be resolved
, 
Mod cannot be resolved to a type
and, 
EventHandler cannot be resolved to a type


I don't know what any of this means, it just looks very confusing and concerning and I feel too uneducated to figure this out so I am asking on here.
java.lang.IllegalStateException: Could not find tools.jar. Please check that C:\Program Files\Java\jre1.8.0_261 contains a valid JDK installation.

Here is what I have tried to do to fix this: Refreshing the project, cleaning the project, updating java.

Here is my Mod Development Kit version: 1.12.2-14.23.5.2854

If you're working with gradle to build Java, you need a Java Development Kit (JDK), not just a Java Runtime Environment (JRE). Gradle uses the compiler that's only found in the JDK, not the JRE.
