Coding in Kotlin to:

1. Explore linting, testing and logging frameworks for Kotlin
2. Understand enough about null safety, lambdas, generics, etc.
3. Assess its compatibility with Java code

Load the project up in Intellij IDEA.

After that, you can:

• Run app via ./gradlew run
• Test code via ./gradlew test
• Check code style via ./gradlew detekt
• Fix code style via ./gradlew detekt --auto-correct

Add hooks to your local copy by running ./gradlew addHooks.

A warning appeared while integrating Mockito into this Kotlin project:

WARNING: A Java agent has been loaded dynamically (...)
WARNING: If a serviceability tool is in use, please run with -XX:+EnableDynamicAgentLoading to hide this warning
WARNING: If a serviceability tool is not in use, please run with -Djdk.instrument.traceUsage for more information
WARNING: Dynamic loading of agents will be disallowed by default in a future release
OpenJDK 64-Bit Server VM warning: Sharing is only supported for boot loader classes because bootstrap classpath has been appended
