Multiple possibilities.

1) Make two artifacts at different Maven coordinates.
2) Make two artifacts at the same Maven coordinate, using classifiers to 
distinguish them. This may run into trouble if some Maven plugin does 
not know how to handle classifiers - *most* plugins do, but I would be 
surprised if all did.
3) Make *three* artifacts: a standalone main program, a WAR artifact, 
and a library artifact that contains the common code. The common code 
has a compile-scope dependency on SLF4J, that's all.
4) Use the Spring Boot plugin, which can generate a dual-use "fat jar" 
which can run standalone or inside a web container. The fat jar contains 
a class loader and a logging backend jar, inside a container the backend 
is ignored, standalone the backend's classes are added to the classpath. 
(Personally, I think that Spring Boot's fat-jar support alone is totally 
worth it, even for projects that do not use Spring and to not run inside 
a Java container. YMMV.)
