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-classic so that I can use logback as the unified logging backend.

I would also eliminate the commons-logging dependency that the third-party lib would let sbt pull in. I do the following in Maven (which is recommended by http://www.slf4j.org/faq.html#excludingJCL):

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

And the question is, how to do the same with sbt?

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!

It works. And my final solution is `libraryDependencies ++= Seq(...).map(_.exclude("commons-logging", "commons-logging"))` – wks Jun 10 '12 at 16:31

Update: Recent versions of sbt (since 0.13?) supports "provided", too. I can just write `"commons-logging" % "commons-logging" % "1.2" % "provided"` – wks Nov 16 '19 at 05:43

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

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

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"))

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

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

Downvoted, cause can lead to the problems when you have more than one 3rd party dependencies, as drexin noted, sorry. – om-nom-nom Jun 09 '12 at 08:39
This solution actually worked for me (removed all the 3rd party dependencies for 1 explicit dependency). – Jane Wayne Dec 12 '16 at 21:40
