How to change logging level for azure-functions-maven-plugin?

Question

I have developed an Azure Function and I run it locally with with "mvn azure-functions:run" command. How do I change the console log level? It appears to be INFO, and prints something like this:

[3/10/18 9:26:38 PM] Generating 1 job function(s)

But I need it to be DEBUG or lower. In my function code, I have a line like this:

context.getLogger().log(Level.FINE, "Created queue client " + queueClient);

This line never prints as it is.

I don't know the actual answer, but here are 2 ideas:

Create a src/main/resources/application.properties with this content:

logging.level.com.azure.cosmos=DEBUG

IN your host.json, put this:

"tracing":
{
  "consoleLevel": "verbose"
}

Neither one of those worked for me, but I think I am on the right track.

I use Lombok for logging config, and you should too.
