This is debug logging from the container - I assume the application you're
launching Maven from uses SLF4J and has the default log level set to DEBUG,
which is then inherited by all code launched from that application. To disable
these messages you need to set the log level for Sisu to INFO (or set the
default log level to INFO) in whatever configuration file you use to configure
your SLF4J backend. For example, if you were using logback:
<configuration>
<root level="DEBUG">
<!-- ...etc... -->
</root>
<logger name="Sisu" level="INFO"/>
<!-- ...etc... -->
</configuration>
Some SLF4J backends also let you set the logger levels programatically, see the
documentation for whichever implementation you're using.
