I have cloned the Gatling Kotlin demo project, using JDK 17, Kotlin 1.3.31 and Gradle 4.4.1. When I try to run the sample test I receive the error: ```auto Could not create service of type ScriptPluginFactory using BuildScopeServices.createScriptPluginFactory(). ``` I am using WSL2 with Ubuntu. Any help would be appreciated. Many Thanks Adrian ---

Hi @aidylewis, Gradle 4.4.1 was released in december 2017! More than 5 years back! Please upgrade! We test for compatibility with Gradle \> 5.0 (but we are planning to raise this because of dependency compatibilities issues) Cheers! ---

Thanks updated Gradle to 7.4.2, set **JAVA\_HOME=/usr/lib/jvm/java-17-openjdk-amd64**. However, **~/projects/gatling-gradle-plugin-demo-kotlin$ gradle gatlingRun** Returns > java.util.concurrent.ExecutionException: org.gradle.api.GradleException: Failed to create Jar file /home/aidy/.gradle/caches/jars-9/87491e8cdb0229bafcb7120e23222513/jackson-core-2.15.2.jar.

Mmmh, this one is strange. But I reproduced it. It seems that we depend on `jackson-core-2.15.2.jar` but there is a class that need Java 19. I will check that and keep you posted. ---

In the meantime, you can use the gradle wrapper we provide, you can even upgrade to the latest version gradle 8.2: ```console ./gradlew wrapper --gradle-version=8.2 ``` It seems like one of our dependency went to build with one version of gradle that make the whole dependency tree uncertain. Look for [AbstractMethodError in builds running Gradle \<7 with plugins built in Gradle 7+ · Issue #18570 · gradle/gradle · GitHub](https://github.com/gradle/gradle/issues/18570) ---

Thanks for your time and patience and I am glad to have found a bug @sbrevet. ---

> [@sbrevet](#): > > `./gradlew wrapper --gradle-version=8.2` Are you aware of this deprecation warning? ```auto ~/projects/gatling-gradle-plugin-demo-kotlin$ ./gradlew wrapper --gradle-version=8.2 Deprecated Gradle features were used in this build, making it incompatible with Gradle 9.0. You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

I installed Gradle 8.2 through sdkman, I am not sure where the gradlew bash script is installing gradle, but it doesn’t seem to be in my path. However, I am very grateful for your help and all the best. ---

Yes, we are aware of such warning. This is the reason why I mentioned we are considering to raise the gradle lower version threshold. (Because of incompatibilty between gradle versions). gradle wrapper (aka `./gradlew`) is a script that installs itself in the project directory. (see `gradlew`, `gradle/wrapper` and `.gradle` directories) So when your working directory is the demo project, you can launch it with: ```console ./gradlew --version ``` This allows to have a gradle version per project. More about the wrapper in the official Gradle documentation [https://docs.gradle.org/current/userguide/gradle\_wrapper.html](https://docs.gradle.org/current/userguide/gradle_wrapper.html) Note: it’s the recommended way to execute gradle by gradle documentation.

The issue with Jackson is actually a bug in gradle. It was fixed in the latest gradle release. ---

@sbrevet We have to update the wrapper version in our samples. ---
