Hello everyone, I have created a new project using http4k generate project -o folder-name -r dD1BQU1BWlFES0FTOEI5Z09FQS1nRDZRU3dCUlEmYz1NYWluJnA9Y29tLmJhdHRpc3RlbGxpLmx1Y2E
but I don't seem to be able to run tests. What am I missing?

$ ./gradlew test
Starting a Gradle Daemon, 8 stopped Daemons could not be reused, use --status for details
> Task :test FAILED

The stack trace is not very helpful

org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':test'.
...
Caused by: org.gradle.api.GradleException: There were failing tests. See the report at: file:///Users/lucabattistelli/repos/backend-test-kotlin-2/Main/build/reports/tests/test/index.html

If you open that index.html file in your browser, what does it tell you?

[Luca Battistelli]

Aha! I had not looked at the stack traces in that page assuming they would be the same
MainClientKt has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0 which I guess it means I have to use JDK 1.8?

Setting

compileKotlin.kotlinOptions.jvmTarget = "1.8"
compileTestKotlin.kotlinOptions.jvmTarget = "1.8"

in build.gradle did the trick!

Maybe http4k generate project should be updated? Or there is a way to make it work with JDK 11 (or 17!)
