How to run Gatling Quickstart Test Case

I am trying to run the Quickstart example with Gatling Gradle plugin 3.5.0 and Gradle 6.0.

I have the following directory structure:

At the root, I run ./gradlew gatlingRun-loadtests.BasicSimulation, making sure the Quickstart Test case package is loadtests and the Class name is BasicSimulation and all I get is:

Deprecated Gradle features were used in this build, making it incompatible with Gradle 7.0.
Use '--warning-mode all' to show the individual deprecation warnings.
See https://docs.gradle.org/6.0/userguide/command_line_interface.html#sec:command_line_warnings

BUILD SUCCESSFUL in 309ms
4 actionable tasks: 4 up-to-date

or when hitting my endpoint:

My endpoint is not reached by any Gatling request.

Any clue on how to get this Quickstart working on Gradle?

You're really looking for trouble using a version released almost 2 years ago.

As of now, the latest version of Gatling is 3.8.3 and the latest version of the plugin is 3.8.3.2.

We also maintain official sample projects, eg https://github.com/gatling/gatling-gradle-plugin-demo-scala/blob/main/build.gradle

You should definitely start from here, instead of fighting old versions that even core committers have lost track.
