Play framework 2 development configuration

Question

How I can setup different configuration for development and production mode in Play 2 application?

I've try to use JVM arguments on application start in development mode like this:

play "run -Dconfig.resource=dev.conf"

or from Play console:

run -Dconfig.resource=dev.conf

but it did not work.

Answer 1

That should work:

play -Dconfig.resource=dev.conf "run"

Anyway I had some problems with -Dconfig.resource so I'm using -Dconfig.file instead

play -Dconfig.file=/full/path/to/your/project_folder/conf/alt_conf.conf "run"
