通过xsbt-web-plugin运行webapp时的公共日志记录问题

Question

我正在尝试使用jcl-over-slf4j来处理一些依赖项的日志记录（通过Dispatch，Authorize.net和Rackspace CloudFiles引入公共日志 - 使用httpclient的任何东西......）。在sbt以外的地方跑步时一切正常，但在通过NoClassDefFoundError跑步时收到container:start。

java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory

我已经通过ivyXML排除了公共记录。

一些配置信息：

object BuildSettings {
  import Resolvers._

  val buildOrganization = "myproject"
  val buildVersion      = "1.0"
  val buildScalaVersion = "2.9.0-1"

  val buildSettings: Seq[Project.Setting[_]] = {
    Defaults.defaultSettings ++
    webSettings ++
    (resolvers += maven2) ++
    (scanDirectories in Compile := Nil) ++
    (ivyXML := Dependencies.globalExclusions) ++
    (libraryDependencies ++= Dependencies.webapp) ++
    Seq(
      name         := "MyProject",
      organization := buildOrganization,
      version      := buildVersion,
      scalaVersion := buildScalaVersion
    )
  }
}

object Resolvers {
  val maven2 = "Java.net Maven2 Repo" at "http://download.java.net/maven/2/"
  val scalaToolsSnapshots = "Scala Tools Snapshot" at "http://scala-tools.org/repo-snapshots/"
  val scalaToolsReleases = "Scala Tools Releases" at "http://scala-tools.org/repo-releases"
}

object Dependencies {

  val liftVersion = "2.4-M5"
  val jettyVersion = "7.4.5.v20110725"

  val lift = Seq(
    "net.liftweb" %% "lift-webkit" % liftVersion % "compile->default" withSources(),
    "net.liftweb" %% "lift-mapper" % liftVersion % "compile->default" withSources(),
    "net.liftweb" %% "lift-widgets" % liftVersion % "compile->default" withSources()
  )

  val jetty = "org.eclipse.jetty" % "jetty-webapp" % jettyVersion % "container"
  val servlet = "javax.servlet" % "servlet-api" % "2.5" % "provided"

  val scalate = "org.fusesource.scalate" % "scalate-core" % "1.5.3" % "compile"

  val slf4j = "org.slf4j" % "slf4j-log4j12" % "1.6.4" % "compile"
  val jclSlf4j = "org.slf4j" % "jcl-over-slf4j" % "1.6.4" % "compile"

  val commonsValidator = "commons-validator" % "commons-validator" % "1.3.1" % "compile"

  val dispatch = "net.databinder" %% "dispatch-http" % "0.8.5" % "compile"
  val dispatchJson = "net.databinder" %% "dispatch-lift-json" % "0.8.5" % "compile"

  val quartz = "org.quartz-scheduler" % "quartz" % "2.1.2" % "compile" withSources()

  val junit = "junit" % "junit" % "4.5" % "test->default"
  val specs = "org.specs2" %% "specs2" % "1.7.1" % "test->default"

  val postgres = "postgresql" % "postgresql" % "8.4-702.jdbc4" % "runtime->default"

  val globalExclusions = <dependencies>
    <exclude org="commons-logging" module="commons-logging" />
  </dependencies>

  val webapp = Seq(
    jetty, servlet,
    scalate,
    slf4j, jclSlf4j,
    commonsValidator,
    dispatch, dispatchJson,
    quartz,
    junit, specs,
    postgres
  ) ++ lift

}

在sbt以外的地方跑步时，我正在使用：

-Dorg.apache.commons.logging.LogFactory=org.apache.commons.logging.impl.LogFactoryImpl

并在/ etc中放置了commons-logging和log4j jar。 在我打包webapp之前，我还通过我的ivyXml排除了log4j jar。 http://articles.qos.ch/classloader.html
