Run application via gradlew with -Xmx and -Xms

I have an application. I run it via

gradlew run-app

Or debug

gradlew debug-app

It works. How do I pass '-Xmx' argument into the application which I run (debug)? Is it possible to do so without edditing build.gradle file?

I found this Gradle unknown command-line option '-X'

I get a similar error when I try

gradlew debug-app -Xmx2000m

Error

FAILURE: Build failed with an exception.

* What went wrong:
Problem configuring task :debug-app from command line.
> Unknown command-line option '-X'.

I tried to create a file gradle.properties in GRADLE_USER_HOME directory (by default, it is USER_HOME/.gradle).

org.gradle.jvmargs=-XX\:MaxHeapSize\=4256m -Xmx4256m -Xms2000m

I also tried to org.gradle.jvmargs=-Xmx2000m in project folder gradle.properties.

And even then when I run an application, I see Commited Memory size is < 520 MiB

And this is when I run it as a normal Java App

In the second case, when I run the application as a normal Java app with -Xms, -Xmx, Commited Memory size is about 3.5 GiB because I passed -Xmx4512m -Xms2512m parameters.

Using application plugin one can use applicationDefaultJvmArgs property

apply plugin: 'application'    
applicationDefaultJvmArgs = ["-Xms1024m", "-Xmx2048m"]

The arguments will be applied to run task and to start script of your application
