Grails: Pass options to the forked JVM

问题

I'm using Grails 2.3.5 and I need to pass an option to the forked JVM. I've tried doing this by setting the JAVA_OPTS environment variable, but that simply gets ignored by the forked JVM. How can I go about passing the forked JVM an option?

I've found this: http://jira.grails.org/browse/MAVEN-177?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel but that's if you're using the Maven plugin I believe. I'm looking for the equivalent but without having to get Maven plugin involved.

According to: http://grails.org/doc/2.3.x/guide/commandLine.html#forkedMode (near the bottom of the section) you can use jvmArgs in your grails.project.fork configuration. In BuildConfig:

grails.project.fork = [
    // ...
    run: [maxMemory:1024, minMemory:64, debug:false, maxPerm:256, jvmArgs: '..arbitrary JVM arguments..']
    // ...
]

Couldn't post a comment. To clarify Andrew's answer, jvmArgs has to be a list.

grails.project.fork = [
    // ...
    run: [maxMemory:1024, minMemory:64, debug:false, maxPerm:256, jvmArgs: ['-Dsome.prop=true', ...] ]
    // ...
]

Using Grails 2.5.1 in forked mode running with the Tomcat 7.0.55.3 plugin, I could not get any of the grails.project.fork.jvmArgs solutions to work. I eventually was able to pass JVM options to the forked process by adding this at the end of my BuildGroovy.config:

grails.tomcat.jvmArgs = ['-jvm_option_here']

See: TomcatServerFactory.groovy
