How to exclude commons-logging from a scala/sbt/slf4j project?

Question

My scala/sbt project uses grizzled-slf4j and logback. A third-party dependency uses Apache Commons Logging.

With Java/Maven, I would use jcl-over-slf4j and logback-c

Answer 1

Add intransitive your 3rd party library dependency, e.g.

libraryDependencies += "foo" %% "bar" % "1.2.3" intransitive

Answer 2

I met the same problem before. Solved it by adding dependency like

libraryDependencies += "foo" % "bar" % "0.7.0" exclude("commons-logging","commons-logging")

or

libraryDependencies += "foo" % "bar" % "0.7.0" excludeAll(ExclusionRule(organization = "commons-logging"))

Answer 3

Heiko's approach will probably work, but will lead to none of the dependencies of the 3rd party lib to be downloaded. If you only want to exclude a specific one use exclude.

libraryDependencies += "foo" % "bar" % "0.7.0" exclude("org.baz", "bam")

or

... excludeAll( ExclusionRule(organization = "org.baz") ) // does not work with generated poms!

Answer 4

For sbt 0.13.8 and above, you can also try the project-level dependency exclusion:

excludeDependencies += "commons-logging" % "commons-logging"
