[slf4j-dev] Fwd: global exclusions in Maven

[Ceki Gülcü]

FYI. I just sent this to Matt Raible (the author of appfuse) who has
asked for global exclusions in Maven.

Hello Matt,

I just wanted to inform you that even without global exclusions in
Maven, it is still possible to exclude commons logging quite
conveniently.

Given that jcl-over-slf4j is a perfect binary replacement for commons
logging, simply declare commons-logging in the provided scope in the
a project top-level pom.xml file.

This translates into the following pom file snippet:

<dependency>
   <groupId>commons-logging</groupId>
   <artifactId>commons-logging</artifactId>
   <version>1.1.1</version>
   <scope>provided</scope>
</dependency>

<dependency>
   <groupId>org.slf4j</groupId>
   <artifactId>jcl-over-slf4j</artifactId>
   <version>1.5.11</version>
</dependency>

There is an SLF4J FAQ entry discussing this same point [1].

I don't believe global exclusions would buy us anything more than what
is already available by declaring CL in the provided scope.

Cheers,
