Gatling using JDBC feeder connecting to SQL Server with Windows Authentication throws error "java.lang.NoSuchMethodError" - jdbc

Question

Learning from this documentation , I tried to use Gatling JDBC feeder to grab data from our SQL Server with Windows Authentication.
I add this dependency in my POM.xml
<!-- https://mvnrepository.com/artifact/dev.code-n-roll.gatling/jdbc-gatling -->
<dependency>
<groupId>dev.code-n-roll.gatling</groupId>
<artifactId>jdbc-gatling_2.12</artifactId>
<version>2.3.0</version>
</dependency>
<!-- https://mvnrepository.com/artifact/io.gatling/gatling-jdbc -->
<dependency>
<groupId>io.gatling</groupId>
<artifactId>gatling-jdbc</artifactId>
<version>3.4.2</version>
</dependency>
<!-- https://mvnrepository.com/artifact/com.microsoft.sqlserver/mssql-jdbc -->
<dependency>
<groupId>com.microsoft.sqlserver</groupId>
<artifactId>mssql-jdbc</artifactId>
<version>7.4.1.jre8</version>
</dependency>
My connection string looks like this
import io.gatling.jdbc.Predef._
val databaseUrl = "jdbc:sqlserver://CentralSQLServer:1433;databaseName=CustomerDB;integratedSecurity=true"
I added integratedSecurity=true because the access method to the SQL server is using Windows Authentication, not using username & password. This works fine when I use vanilla Java with JDBC.
Then I define the JDBC Feeder
val mySQLFeeder = jdbcFeeder(databaseUrl, "", "", "SELECT * FROM [CustomerDB].[dbo].[Users]")
I put empty String in username and password sections , since I don't have it.
Running the Gatling test using mvn gatling:test , I see this error is thrown by Gatling

It looks like Gatling JDBCFeeder method complains about my connection string using integratedSecurity=true since in the documentation we should use username and password. The thing is there are no username and password in my case.
Is there any way to solve this issue?
Thanks.

Thanks #GeorgeLeung and #StephaneLandelle .
The issue is caused by dependency version conflict.
The gatling-jdbc version must align with the gatling-core version.
Change the dependencies in POM.xml to this below does solve the issue.
<properties>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>

The gatling-app does include the gatling-jdbc , so we don't need to extra add it.
