Playframework 2.4 Java - default "play-java" template takes over 1 minute to run / doesn't hot reload -


i'm using default "play-java" template play framework 2.4, , when run activator run takes 1 minute , 40 seconds load. typical? seems way slow.

additionally, if make changes controller... adding system.out.println("test") index(), update next time hit refresh in browser taking 10 seconds. if remove it, hot reloading stops working. takes forever reload , failing error:

this leaves me option stopping activator run , rerunning it... , waiting 1 minute , 40 seconds. makes development super slow.

i noticed same. try commenting out unused plugins , library dependencies in project/plugins.sbt , build.sbt.

try making sure java 8 version (by running java -version) stable - not access (ending in -ea) or beta.
