Hi Team ,

I’m trying to upgrade the version of lagom from 1.3.1 to 1.4.0 .
I did follow the migration guide and upgraded the version of akka(2.5.21) and play (2.7.0) .
Java - 1.8

When i execute the maven goal lagom:runAll .

Please help me fix this .

Getting the below exception ,

Hi,

Did you follow Migration guide for 1.4.x?

Hi Alan ,

Yes i did follow the lagom+ Java migration guide .

https://www.lagomframework.com/documentation/latest/java/Migration14.html

And the play version used is 2.6.21 ( and not 2.7.0)

Thanks in advance,
Ramya

Is there are reason why you are specifying Play and Akka versions explicitly? It should be derived from Lagom version automatically.

Hi Alan ,

We have used the akka actor system , and there was an explicit dependency on play-netty-server (when the lagom version was 1.3.1) which is changed to play-akka-http-server.
And in the migration guide i did see the that akka and play versions , so added it here .

Hi,

I have never explicitly set any akka/play related versions.
I suggest removing explicit definitions.

Alan
