# Interface Logger

All Superinterfaces:
  `org.slf4j.Logger`

public interface Logger extends org.slf4j.Logger

An extension to the SLF4J `Logger` interface, which adds the `quiet` and `lifecycle` log levels.

You can obtain a `Logger` instance using `Logging.getLogger(Class)` or `Logging.getLogger(String)`. A `Logger` instance is also available through `Project.getLogger()`, `Task.getLogger()` and `Script.getLogger()`.

CAUTION! Logging sensitive information (credentials, tokens, certain environment variables) above `debug(java.lang.String, java.lang.Object...)` level is a security vulnerability. See our recommendations for more information.
