How do I do logging in a cli Command?

[Josh Rehman]

Hi there,

I'm writing a CLI using dropwizard and want to log some stuff during processing. However, my Command doesn't seem to pick up the config.yml settings for logging, and I'm not sure why.

Note that logging does work in my code, but only at the "WARN" level and above (which is probably a default somewhere).

My application is hosted at https://github.com/javajosh/csv-demo

The primary file is https://github.com/javajosh/csv-demo/blob/master/src/main/java/com/javajosh/csvdemo/cli/ProcessCSV.java

Logging config is set at https://github.com/javajosh/csv-demo/blob/master/config.yml

Thanks for your help!

After digging around in Dropwizard source, I was able to produce a workaround where I can override the Bootstrap log level in the Application subclass. However, I still can't modify appenders, etc.

Hi Josh,

Have you looked at the ConfiguredCommand class? https://www.dropwizard.io/en/latest/manual/core.html#man-core-commands-configured

It looks like if you extend `ConfiguredCommand` instead of `Command` it'll make your config available to your command, and it should initialize logging using the config: https://github.com/dropwizard/dropwizard/blob/master/dropwizard-core/src/main/java/io/dropwizard/cli/ConfiguredCommand.java#L83

Does that work in your case?
