How do I edit the default build command?

Currently the default build command when I click run without debugging in VS code is:

C:\Program Files (x86)\Common Files\Oracle\Java\javapath\java.exe '-Xms1g', '-Dfile.encoding=UTF-8', '-Dapple.awt.UIElement=true', '-jar', 'c:\Users\broom\AppData\Roaming\Garmin\ConnectIQ\Sdks\connectiq-sdk-win-6.4.1-2023-12-04-6cafd260d\bin\monkeybrains.jar', '-o', 'bin\app3.prg', '-f', 'c:\Users\broom\OneDrive\Documents\Projects\SMARTWATCH\Garmin\app3\app3\monkey.jungle', '-y', 'c:\Users\broom\OneDrive\Documents\Projects\SMARTWATCH\Garmin\keys\app1key\developer_key', '-d', 'venu3_sim', '-w'

I just want to edit the '-Xms1g' to something else because I always get Error occurred during initialization of VM
Initial heap size set to a larger value than the maximum heap size

Thanks

Try setting the _JAVA_OPTIONS environment with the Java options you want.

But that sets the default value, when the build runs, it's default value of -Xms1g overrides whatever default is set in the systems environment settings.

Per discussion on the internet, _JAVA_OPTIONS overrides what's set on the command line.

It works for me on Windows, and I'm fairly sure it's also worked for me on macOS and Linux.

>echo %_JAVA_OPTIONS%
-Xmx4g

When I run the build from VS Code, I see this in the output:

Executing task: C:\Program Files\Eclipse Adoptium\jdk-17.0.4.101-hotspot\bin\java.exe -Xms1g ...

...

Picked up _JAVA_OPTIONS: -Xmx4g

"So far I have found out that:

JAVA_OPTS is not used by the JDK, but by a bunch of other apps (see this post).
JAVA_TOOL_OPTIONS and _JAVA_OPTIONS are ways to specify JVM arguments as an environment variable instead of command line parameters.
- The are picked up by at least java and javac
- They have this precedence:
  1. _JAVA_OPTIONS (overwrites the others)
  2. Command line parameters
  3. JAVA_TOOL_OPTIONS (is overwritten by the others)"

well crap my heck it works.

so I already had my _JAVA_OPTIONS set but changing it to something else and back to the original fixed it? unless the original one was just wrong but I don't know its gone now.

Thanks for the help
