How to use my own configuration?

There are 4 different ways for you to supply a custom configuration file:

• supply this system property custom.logging.configuration at the commandline, with a value pointing to your config file
• supply the environment variable MAVEN_CUSTOM_LOGGING_CONFIG and put the path to your config file as it's value
• put config file maven-custom-logging.yml in your $MAVEN_HOME/conf directory
• put config file maven-custom-logging.yml in your $HOME directory
