2.0.0-rc-1 breaks slf4j config via command line

[oehme]

I want to be able to get selective debug logging, e.g. using -Dorg.slf4j.simpleLogger.log.org.apache.maven.lifecycle=debug. However, this only works on the first build that the daemon runs. As soon as you run a second build, the slf4j config is reset and the command line argument is ignored. This used to work in 2.0.0-beta-1

I think it works when using a new daemon. However, those properties seem to not be reset correctly:

➜  maven git:(master) mvnd --stop && \
    (mvnd -Dorg.slf4j.simpleLogger.log.org.apache.maven.lifecycle=debug foo | grep DEBUG | wc -l) && \
    (mvnd -Dorg.slf4j.simpleLogger.log.org.apache.maven.lifecycle=info foo | grep DEBUG | wc -l) && \
    (mvnd -Dorg.slf4j.simpleLogger.log.org.apache.maven.lifecycle=debug foo | grep DEBUG | wc -l)
     152
       0
       0

So debug works fine on a new daemon, but if the logger has been set in a previous run to info, it cannot be reset to debug...

Good news is that is seems already fixed when building mvnd 2.0.0-rc-2-SNAPSHOT with Maven 4.0.0-rc-2-SNAPSHOT:

➜  mvnd git:(master) ✗ (mvnd -v | grep "Apache Maven") && mvnd --stop && \
    (mvnd -Dorg.slf4j.simpleLogger.log.org.apache.maven.lifecycle=debug foo | grep DEBUG | wc -l) && \
    (mvnd -Dorg.slf4j.simpleLogger.log.org.apache.maven.lifecycle=info foo | grep DEBUG | wc -l) && \
    (mvnd -Dorg.slf4j.simpleLogger.log.org.apache.maven.lifecycle=debug foo | grep DEBUG | wc -l)

Yes, this was fixed in rc-2

It still works:

➜  mvnd git:(buffer-helper-rewrite) (mvnd -v | grep "Apache Maven") && mvnd --stop && \

    (mvnd -Dorg.slf4j.simpleLogger.log.org.apache.maven.lifecycle=info foo | grep DEBUG | wc -l) && \
