1. Change your mod ID. Not only is it invalid (must be all lowercase), it also bad. If your mod is called "Terrain Mod 2020" then your mod ID should be "terrainmod2020" or "terrain_mod_2020". Do not abbreviate.

I did this but to no avail

I am now using java 8 but I am not seeing any direct difference but I updated the gradle scan

In you mods.toml file, right after your modid:

[[mods]] #mandatory
modId="terainmod2020" mandatory   <----------
version="1.15.2-1.0.0" #mandatory

You missed a "#", it should be

#mandatory

How much RAM do you have in your computer?

8G might be too much. 4-6G is enough.

Same Error for free Is there Any help/Fix??

If anyone is still having problems with this, use Java 8 not just for coding, but also for gradlew genEclipseRuns/genVSCodeRuns/genIntellijRuns.
