What is the best way to get Ivy classifiers for project dependency?

[Ezh]

Hi all,

I suspect that there is no one depends their tasks on cross-publish. It is about my previous question. So sad.

I read IvyActions.scala. SBT realy simple, but there isn't much code comments ;-) I got standard update-sbt-classifiers and add to it library-dependencies. Neither original update-sbt-classifiers nor original update-classifiers fetch sources for library-dependencies. This is my way to do it:

myTask = (ivySbt, classifiersModule in updateSbtClassifiers, updateConfiguration,
    ivyScala, target in LocalRootProject, appConfiguration, alignPath, libraryDependencies, streams) map {
      (is, origClassifiersModule, c, ivyScala, out, app, path, libDeps, s) =>
        withExcludes(out, origClassifiersModule.classifiers, lock(app)) { excludes =>
          import origClassifiersModule.{ id => origClassifiersModuleID, modules => origClassifiersModuleDeps }
          // do default update-sbt-classifiers with libDeps
          val extClassifiersModuleDeps = origClassifiersModuleDeps ++ libDeps
          val customConfig = GetClassifiersConfiguration(origClassifiersModule, excludes, c, ivyScala)
          val customBaseModuleID = restrictedCopy(origClassifiersModuleID, true).copy(name = origClassifiersModuleID.name + "$" + label)
          val customIvySbtModule = new is.Module(InlineConfiguration(customBaseModuleID, ModuleInfo(customBaseModuleID.name), extClassifiersModuleDeps).copy(ivyScala = ivyScala))
          val customUpdateReport = IvyActions.update(customIvySbtModule, c, s.log)
          val newConfig = customConfig.copy(module = origClassifiersModule.copy(modules = customUpdateReport.allModules))
          val report = IvyActions.updateClassifiers(is, newConfig, s.log)
          ... now process customUpdateReport
}

Is there more simple way? Google search don't much know about GetClassifiersConfiguration. It would be wonderful to have such simple solution like SBT itself.

Thank you,
