suppressing logging output during mvn compile

[Elango Cheran]

Hi,

I like to have logging configured in such a way that behaves differently when running the program/uberjar vs. compiling/testing.  When running the program, I want logging output to go to a file in the directory from where the program was launched.  When just compiling or testing, I want there to be no file output from logging.

I use Maven when I write in Scala or Java, and the way I achieve this desired logging output behavior most simply is to have a separate log4j.properties in src/main/resources and src/test/resources.  The src/test/resources config file is honored during 'mvn compile' and 'mvn test', but the src/main/resources config file is what is included in the uberjar.

I'm writing Clojure code that I have integrated as a subjproject into a Maven project.  I did/do development via Leiningen, so I am going to maintain 2 build files that I will keep in sync (for as long as that is feasible).  But ultimately, the Maven pom.xml will be the canonical build file for my subproject.

I have achieved the desired behavior in my Leiningen project.clj.  The proper testing log4j.properties is honored during 'lein compile' and 'lein test', but the uberjar has the main log4j.properties.  Just as I would hope.

The strange thing is that when I run 'mvn compile', there is a logging output file created, and because 'mvn compile' gets called before most every other Maven phase, it's unavoidable in basically every Maven task.  

FYI, the pom.xml that I have created for Maven is based off of what I got from 'lein pom' and modified to handle a few other things (ex: using Expectations via JUnit).  Here is the relevant portion of my pom.xml:

Is this an issue within clojure-maven-plugin?  If so, is there a workaround for this?  If not, where can I follow up on this?

Thanks,
