Cordova Could not reserve enough space for 2097152KB object heap

Solution 1:

Try again after increasing your Java VM(?) memory size.

Here is how to fix it on a Windows platform:

Go to Start -> Control Panel -> System -> Advanced(tab) -> Environment Variables -> System Variables -> New:
Variable name: _JAVA_OPTIONS
Variable value: -Xmx512M

Don't ignore the score and underscore characters.

Solution 2:

I had the exact same problem. I switched to use 64-bit JDK as suggested in here and it worked fine. I was using Ionic 3.5.0 on Windows 10.

Solution 3:

args.push('-Dorg.gradle.jvmargs=-Xmx2048m') 
into 
args.push('-Dorg.gradle.jvmargs=-Xmx1024m');

on the following location files.

1. project-folder\platforms\android\cordova\lib\builders\GradleBuilder.js
