How to increase Java Heap Memory for CMD 6.1.1.76 ?

I think these are no longer valid methods:

I'm getting a Java heap exception when running

sencha app build

specifically while slicing images (I don't want to skip this)

You have to edit sencha.cfg file which is located in your Cmd folder. If you are on Windows - most probably here:

C:\Users\<user>\bin\Sencha\Cmd\6.1.1.76

In it, you will find the part with JVM startup arguments:

#------------------------------------------------------------------------------
# These are the JVM startup arguments. The primary things to tweak are the JVM
# heap sizes.
# java.awt.headless=true - required to make phantomjs (used by theme slicer)
#                          work in headless environments

# cmd.jvm.args=-Xrunjdwp:transport=dt_socket,server=y,address=8888,suspend=n -Xms128m -Xmx2048m -Djava.awt.headless=true
cmd.jvm.args=-Xms128m -Xmx1024m -Dapple.awt.UIElement=true

You can find more info about configuration files in the Sencha Cmd Docs.

EDIT: From Cmd 6.5.0 this no longer works. You will have to use _JAVA_OPTIONS

# On previous versions, this file provided a way to specify the cmd.jvm.* properties
# to control the execution of the JVM. To accommodate all possible execution scenarios
# support for these properties has been removed in favor of using the _JAVA_OPTIONS
# environment variable.
