[JBoss JIRA] (DROOLS-5021) ClassCastException thrown when deserializing components of a Generic command

Karel Suta commented on DROOLS-5021:
------------------------------------
[~northgorky] Sorry for the delay.
Thanks for very detailed reproducer, it helped me a lot.
I was able to successfully call the container when I adjusted dependency scope in
build.gradle to compileOnly.
Please change scope of kie-api, kie-server-client and drools-core to compileOnly.
These artifacts are already included in Kie server, therefore adding them in kjar causes
class resolution issues like you see in your project.
In general you should avoid having runtime dependencies on any artifact which is already
available in Kie server. Kie server contains all engine artifacts and their dependencies,
so your kjar should depend just on your own dependencies in runtime scope. Engine
dependencies should be limited just to compile only scope.
