How to change the location of twirl templates for integration tests?

Question

I'm trying to use twirl as part of my integration tests.

My integration tests have an HTTP simplicator that mimics a real world service. To implement this simplicator in the tests, I'm using spray-can embedded HTTP server which needs to spit out responses based on twirl templates.

My tests are located at /src/it/scala so naturally I want to place these twirl templates inside /src/it/twirl. This doesn't work since the twirl compiler ignores this directory.

If I place the twirl templates in /src/main/twirl, everything works fine - but I'm trying to avoid this because I don't want these templates to clutter the production package (the templates only come into play in the tests so they should only compile inside when the tests are run).

How can I tell the twirl compiler to look for templates in the new directory?

You should really be using sourceDirectory in twirlCompile that by default is set to:

sourceDirectory in twirlCompile <<= (sourceDirectory in Compile) / "twirl"

Redefine the sourceDirectory setting for the twirlCompile task for the IntegrationTest config. The following should work (it's yet to be verified).

sourceDirectory in twirlCompile in IntegrationTest := (sourceDirectory in IntegrationTest).value / "twirl"
