applicationDefaultJvmArgs is exactly what is needed to configure the JVM when using ‘gradle run’, however it is very difficult to find this option. http://www.gradle.org/docs/1.7/release-notes#specify-default-jvm-arguments-for-the-application-plugin is the only place where I was able to find it, with quite a bit of noise along the way.
