I'm using the default "play-java" template for Play Framework 2.4, and when I run activator run it takes 1 minute and 40 seconds to load. Is this typical? It seems way to slow.
Additionally, if I make changes to Controller... just adding System.out.println("test") to index(), it will update next time I hit refresh in the browser taking about 10 seconds. If I then remove it, the hot reloading stops working. It takes forever to reload and eventually failing with the error:

This leaves me with the only option stopping activator run and rerunning it... and then waiting another 1 minute and 40 seconds. This makes development super slow.
I noticed the same. Try commenting out unused plugins and library dependencies in
project/plugins.sbtandbuild.sbt.Try making sure that Java 8 version (by running
java -version) is stable - not early access (ending in-ea) or beta.
