java.lang.NoClassDefFoundError: io/gatling/core/check/DefaultFindCheckBuilder

Hi!

I'm trying to do some database performance tests with your library, but I've an error.
Maybe I did something wrong.
Here's my configuration :

My pom.xml dependencies :

<dependency>
	<groupId>io.gatling.highcharts</groupId>
	<artifactId>gatling-charts-highcharts</artifactId>
	<version>3.7.3</version>
	<scope>test</scope>
</dependency>
<dependency>
	<groupId>io.gatling</groupId>
	<artifactId>gatling-app</artifactId>
	<version>3.7.3</version>
</dependency>
<dependency>
	<groupId>io.gatling</groupId>
	<artifactId>gatling-recorder</artifactId>
	<version>3.7.3</version>
</dependency>
<dependency>
	<groupId>io.gatling</groupId>
	<artifactId>gatling-jdbc</artifactId>
	<version>3.7.3</version>
</dependency>
<dependency>
	<groupId>ru.tinkoff</groupId>
	<artifactId>gatling-jdbc-plugin_2.13</artifactId>
	<version>0.5.0</version>
</dependency>

My Scala class :

class TestJDBCFeeder1UserSimulation extends Simulation {

  val dataBase: JdbcProtocolBuilder = DB
    .url("jdbc:postgresql://...:25060/defaultdb")
    .username("...")
    .password("...")

  val scn: ScenarioBuilder = scenario("1 user Select all client")
    .exec(jdbc("select client").query("SELECT * FROM client").check(simpleCheck(_.nonEmpty)))

  setUp(
    scn.inject(atOnceUsers(1)),
  ).protocols(dataBase)
    .maxDuration(60)
}

The error :

Do you have any idea?

Thanks.

Hello!
release 0.5.0 is not compatible with Gatling 3.7.x. reason gatling/gatling#4195. We are waiting fix in 3.8.x
Could you try downgrade Gatling’s version?

I had to downgrade to the 3.6.1 version, thank you for the tip !
