incompatibility with gatling-2.2.2

[ksgr999]

With latest version of gatling-2.2.2 Unable to use this plugin...
I have gatling-amqp_2.11:0.5 in project dependencies...

When run performance test getting the below error.
Missing or invalid dependency detected while loading class file 'AmqpProtocol.class'.
Could not access type Protocol in package io.gatling.core.config,
because it (or its dependencies) are missing. Check your build definition for
missing or conflicting dependencies. (Re-run with -Ylog-classpath to see the problematic classpath.)
A full rebuild may help if 'AmqpProtocol.class' was compiled against an incompatible version of io.gatling.core.config.
one error found

Can you help me on this one to work on gatling-2.2.2

Hi, @ksgr999
I'm sorry that I've left AMQP job, so this library still lives with gatling-2.2.0.
Could you try @LuboVarga 's fork? It supports 2.2.2 I think.

Thanks for suggestion, but unfortunately my fork still have not finished migration to gatling-2.2.2. There are major changes which are not compatible with philosophy of amqp plugin code/actor structure. I am on a good way, but these days I have no time to finish migration.

On the other side, my fork have some nice improvements in "rpc" way of using amqp. You can make request through amqp with correlation id (by default, generated automatically) and than wait for response (each step should have its own queue!). Response is correlated by correlation id from last request (stored in session) by default. Than you can see also "response" time for request.

If my memory is ok, this is last working branch for my fork: https://github.com/LuboVarga/gatling-amqp/commits/moreStepsInSingleAction (still on older gatling base!)

WIP branch with migration to new gatling is here: https://github.com/LuboVarga/gatling-amqp/tree/migratingToGatling2.2.2

@ LuboVarga Thanks for information and nice work!
I'd like to check your 2.2.2 branch in this weekend.

Found that some '???' implementations still exist although it can be compiled on 2.2.2.
So then, we have much more time to satisfy backward compatibility.
I'd like to finish it within this year :)

I would be also pleased. I do not have currently enough time to help (push migration further), but it can change from week to week. I will have migration need on my mind and I will try to make it work, if I would have time.

PS: I was a bit lost when making migration done. It is probably due to gatling 2.2.2 has changed a bit philosophy of how actors are done (hidden behind io.gatling.core.action.Action instead directly working with Actor).
