Alpakka 1.1.2 got version conflict with akka-actor 2.6.1

Akka Akka Streams & Alpakka
1

Hi there,

I am using akka-actor-typed 2.6.1. Since akka-camel has been removed from 2.6, I tried to use akka-stream-alpakka-xml 1.1.2 as a replacement to process xml source.

But since akka-alpakka 1.1.2 is based on Akka Streams 2.5.23, I got runtime error as below:

Exception in thread "main" java.lang.IllegalStateException: Detected possible 
incompatible versions on the classpath. Please note that a given Akka version 
MUST be the same across all modules of Akka that you are using, e.g. if you 
use [2.6.1] all other modules that are released together MUST be of the same 
version. Make sure you're using a compatible set of libraries. Possibly 
conflicting versions [2.6.1, 2.5.23] in libraries [akka-actor:2.6.1, akka-
slf4j:2.6.1, akka-stream:2.5.23, akka-protobuf:2.5.23, akka-actor-typed:2.6.1]

How should I use akka-stream-alpakka with akka-stream 2.6.1?

I also noticed a solution by " dependencyOverrides ":
https://www.scala-sbt.org/release/docs/Library-Management.html?_ga=2.7467058.1093767181.1579273281-1459313816.1579075376#Overriding+a+version

Will it work?

Thanks

Hi there,

Please add the Akka dependencies pulled in by Alpakka XML (akka-stream and akka-protobuf) to your build explicitly with the Akka version you use.

Cheers,
Enno.
