Run application via gradlew with -Xmx and -Xms

Question

I have an application. I run it via

gradlew run-app

Or debug

gradlew debug-app

It works. How do I pass \'-Xm

Answer 1

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

Answer 2

Firstly, thanks @ToYonos for leading me to the right direction.

Secondly, I found the solution here https://stackoverflow.com/a/9648945/4587961. I ran my app from command line.

set GRADLE_OPTS=-Xms1724m -Xmx5048m
gradlew debug-app

Note, CMD Windows command SET works locally, so if you close your terminal, GRADLE_OPTS will not be set. For Linux, you can use

export GRADLE_OPTS=WHATEVER

This is what I wanted to achieve.

Answer 3

Add this in your gradle.properties file :

org.gradle.jvmargs=-Xmx2000m

From here

org.gradle.jvmargs

Specifies the jvmargs used for the daemon process. The setting is particularly useful for tweaking memory settings. At the moment the default settings are pretty generous with regards to memory.

edit : my answer what about the gradle daemon jvm, not the app jvm. You have to use the jvmArgs property

The extra arguments to use to launch the JVM for the process. Does not include system properties and the minimum/maximum heap size.
