[2.3.7] [java] TimeoutException: Futures timed out after

[stefaan luckermans]

I recently migrated from 2.2.2 to 2.3.7


Now (not all the times, but must of the times) when I start play , I get the following error

java.util.concurrent.TimeoutException: Futures timed out after [300000 milliseconds]

     scala.concurrent.impl.Promise$DefaultPromise.ready(Promise.scala:219)

     scala.concurrent.impl.Promise$DefaultPromise.result(Promise.scala:223)

     scala.concurrent.forkjoin.ForkJoinWorkerThread.run(ForkJoinWorkerThread.java:107)

In the terminal screen I see:

Does anyone know what causes this error and how to resolve it ...


Thank you,

Could you solve this? I get the same error and have no clue what's going on.

Hi Stefaan, Kristian,

It looks like a problem with the new sbt server support in Activator.

Activator UI adds a `fork in run := true` to your build. To get the activator or sbt command line working again, remove or comment out that line, or set it to false. Then it will use Play's normal development run again.

Cheers,
Peter
