Force project parameters on startup

Hi how can I configure my project which is deployed with codepipeline to ec2 and elastic beanstalk to use jvm params like this:

-Xms512M -Xmx1024M -Xss1M -XX:+CMSClassUnloadingEnabled

can I set this parameters as project parameters in config?

Its a playframework project

Thanks in advance

I want to add these parameters to my scala project
