First of all, I think this error message is very vague. It comes up in multiple situation. It should be made more clearer what is the underlaying issue so it helps to debug.

Initially it was coming up after hitting first url on running server where Module was not initialized (due to not being in root package or not configured in applicaiton.conf)

Not it is coming up due to I think some non resolvable dependency which I can't figure our. Anything that AkkaHttpServer needs that is missing?

This error only happens when I am using WSClient . If I hit the same URL again next time I get different error:

"1) No implementation for play.api.libs.ws.WSClient was bound. while locating play.api.libs.ws.WSClient"

My POM does have following:

<groupId>com.typesafe.play</groupId>

<artifactId>play-ws_${play2-scala.version}</artifactId>

<version>${play2.version}</version>

</dependency>

<groupId>com.typesafe.play</groupId>

<artifactId>play-akka-http-server_${play2-scala.version}</artifactId>

<version>${play2.version}</version>

<scope>runtime</scope>

</dependency>

If I remove use of WSClient it goes away.

It works if I use play-ahc-ws instead of play-ws.

<groupId>com.typesafe.play</groupId>

<artifactId>play-ahc-ws_${play2-scala.version}</artifactId>

<version>${play2.version}</version>

</dependency>

play-ws is just the API. play-ahc-ws is the AsyncHttpClient-based implementation.

Thanks for clarification. I initially added play-ws based on play-maven-plugin suggestion later found the play-ahc-ws from play-ws git page.
