jruby pass jvm arguments to rake task

Question

How do i pass jvm arguments like Xmx to a rake task in jruby? Am using rvm and running the rake task "rake db:migrate".

Thanks!

Answer 1

Rather that put the entire path, if jruby is already the Ruby you're using (for example, with rvm) such that just typing rake would be using jruby, you can use a double dash to send the arguments to the jvm.

Examples:

bundle exec rake -- -J-Xmx1024m (if you're using bundler)

rake -- -J-Xmx1024m
