excluding transitive dependencies

[Andrew Mullins]

I can't seem to get this to work...

this doesn't seem to do anything

"commons-validator" % "commons-validator" % "1.3.1" exclude("org.apache.commons", "commons-logging")

this works but excludes all dependencies (I only need to exclude commons-logging)

"commons-validator" % "commons-validator" % "1.3.1" intransitive()

What am I missing?

I think the groupId is not "org.apache.commons" but just "commons-logging" see for example http://search.maven.org/#search%7Cga%7C1%7Ccommons-logging

Well, that didn't work, either.

I know it's not being brought in by another dependency because I can change the commons-validator dependency to intransitive and the commons-logging jar isn't added.

Looking at the dependencies of commons-validator, I see that some of its dependencies also depend on commons-logging (I wonder if this makes a difference).

My current commons-validator dependency looks like:

"commons-validator" % "commons-validator" % "1.3.1" exclude("commons-logging", "commons-logging")

It seems that the jar is being excluded when I package the web app (no commons-logging in WEB-INF/lib). However, when I run my app via xsbt-web-plugin with container:start, commons-logging-1.0.4.jar is being loaded from somewhere...

The whole reason for my posting this is that I am receiving a NoClassDefFoundError at runtime:

    slf4j, jclSlf4j,

    commons_validator,

    httpcore, httpclient,

    quartz,

    junit, specs,

    postgres

  ) ++ lift ++ dispatch

}

Can anyone give me some insight on the NoClassDefFoundError for LogFactory?

Thanks,

Andy

I changed my dependencies a bit - now using logback for logging.

I don't think I had to change anything outside of the project

object Dependencies {

  ...

  val slf4jApi = "org.slf4j" % "slf4j-api" % "1.7.1"

  val slf4jJcl = "org.slf4j" % "jcl-over-slf4j" % "1.7.1"

  val slf4jlog4j = "org.slf4j" % "log4j-over-slf4j" % "1.7.1"

  val logback = "ch.qos.logback" % "logback-classic" % "1.0.7"

  val commonsValidator = "commons-validator" % "commons-validator" % "1.3.1" withSources()

  ...

  val globalExclusions = <dependencies>

    <exclude org="commons-logging" artifact="commons-logging" />

  </dependencies>

}

object BuildSettings {

  ...

  val buildSettings: Seq[Project.Setting[_]] = {

    Defaults.defaultSettings ++

    ... // webSettings, resolvers, etc

    (ivyXML := Dependencies.globalExclusions) ++

    ... // project name, organization, version

  }

}

Which sbt version do you use? There were some changes 0.12.0 wrt exclusion.
