Hi Gatling Community Team, I need to check the log for performance execution on cursor based pagination scripts in jenkins. but the build.gradle always shows error with log parameters such as at logHttp & logLevel ```gradle plugins { id("scala") id("io.gatling.gradle") version "3.9.0" } gatling { logHttp = io.gatling.gradle.LogHttp.FAILURES logLevel = "WARN" } repositories { maven { url = uri("https://repo1.maven.org/maven2/") } } ``` Error message : ```plaintext Cannot access 'io.gatling.gradle.JvmConfigurable.Trait.FieldHelper' which is a supertype of 'io.gatling.gradle.GatlingPluginExtension'. Check your module classpath for missing or conflicting dependencies ``` Please help me solve this issue ---

Hi @RudraGanesh, What is your version of gradle? What is your version and vendor of the JVM? Which command does produce such error? And I think you should have `logHttp = 'FAILURES'`. Cheers! ---

Hi @sbrevet , thanks for responding please find the below details Gradle : 7.5 Kotlin: 1.6.21 Groovy: 3.0.10 JVM: 11.0.12 (Azul Systems, Inc. 11.0.12+7-LTS). error is not triggered by any command but its notified by IntelliJ as error and during execution there is no log generated for http failures. I tried with logHttp = ‘FAILURES’ but i get below error Type mismatch. Required:LogHttp! Found:String ---

Old Gradle Kotlin DSL (would have helped to mention you were using this) compatibility issue. Please upgrade your plugin version (the latest one as of now is 3.9.0.3). ---

What you are doing is nonsense. You have the issue mentioned in this thread’s title because you are using an outdated version of the gatling gradle plugin, which I told you to upgrade. And now you’re trying to use the bundle instead and use a version that doesn’t exist?! ---
