Scala make takes 10s even with no changes whilst Activator is sub-second Follow

Hi all,

I am working on a hello-world Scala/Play app in Intellij IDEA 14.1.1

I am running a very simple test - see below.

Running just this test through Intellij takes 10s even without any changes to the file i.e. no recompilation.

When I have Typesafe activator running it runs all 3 tests in 793 ms.
And even when I make a change it compiles in under a second.

The intellij log output is below. The long delay occurs after the second line for 10s.

Any suggestion as to what I should be doing to make this faster?

Settings screenshots are attached. I've tried various combo's but it hasn't made any difference.

Thanks,
Will
