I just was starting to make a mod and followed a tutorial on internet but when i ran on this problem i couldn't fix it. My jvmargs at gradle.properties are set to 1G of memory ram and i don't know where to change that 3G Ram he wants (Could not reserve enough space for 3145728KB object heap) (my pc has only 3.24 Gb usable so i know the problem is with the ram space). 

this is what was inside my gradle.properties

 

# Sets default memory used for gradle commands. Can be overridden by user or command line properties.
# This is required to provide enough memory for the Minecraft decompilation process.
org.gradle.jvmargs=-Xmx1G
org.gradle.daemon=true
org.gradle.java.home=C:/Program Files/Java/jdk1.8.0_151

 

Please help me solve this.
