websocket in gatling

I am trying to use websocket in gating 2.0.0-M3a.

After following the instruction to build the websocket jar: gatling-websocket-0.0.8.jar and copies to the lib directory. I put import in the scala test file:

import com.giltgroupe.util.gatling.websocket.Predef._

But get errors:

GATLING_HOME is set to /Users/shawna.qian/jive_code/qa/performance/gatling-charts-highcharts-2.0.0-M3a
15:18:03.681 [ERROR] i.g.a.ZincCompiler$ - bad symbolic reference. A signature in Predef.class refers to term grizzled
in package which is not available.
It may be completely missing from the current classpath, or the version on
the classpath might be incompatible with the version used when compiling Predef.class.

Wondering if somebody use the websocket on this version before?

This project is a third party which is built against Gatling 1, not Gatling 2.
We’ve started integrating it in Gatling after M3a (so it hasn’t been released yet and is a WIP).

Do you have an ETA on this integration?

Thx

Any updates on this ?
I can’t find the WS pluging in any mvn repo, however the docs still selling that Gatling supports WS.

Does anyone knows what is the current state of it ?

What makes you believe you need a plugin?

Gatling’s Websocket support has been available without any additional dependencies for a few months now.
Please read the documentation.
