【问题描述】：

我的 build.sbt 是这样写的：

name := """scala-hbase"""

version := "1.0"

scalaVersion := "2.11.2"
//scalaVersion := "2.10.4"

/* HBase dependencies */
resolvers ++= Seq(
  "Apache Repo"   at "https://repository.apache.org/content/repositories/releases",
  "Thrift-Repo"   at "http://people.apache.org/~rawson/repo",
  "ClouderaRepo"  at "https://repository.cloudera.com/content/repositories/releases",
  "ClouderaRcs"   at "https://repository.cloudera.com/artifactory/cdh-releases-rcs",
  "Twitter Maven" at "http://maven.twttr.com",
  "MVN Repo" at "http://mvnrepository.com/artifact",
  "releases"      at "http://scala-tools.org/repo-releases"
)

// Hbase 0.94 / Hadoop 2.5.2
libraryDependencies ++= Seq(
    //"org.apache.zookeeper" % "zookeeper" % "3.4.6",
    //"org.specs2" %% "specs2" % "2.4.5" % "test",
    "org.apache.hadoop"     % "hadoop-core"         % "1.2.1",
    "org.apache.hbase"      % "hbase"               % "0.94.16",
    "com.twitter"    %% "scalding-args"  % "0.10.0",
    "com.twitter"    %% "scalding-core"  % "0.10.0",
    "com.twitter"    %% "scalding-date"  % "0.10.0"
)
// Uncomment to use Akka
//libraryDependencies += "com.typesafe.akka" % "akka-actor_2.11" % "2.3.3"


But I got some unresolved dependencies

【解决方案1】：

Scalding 0.13 现已发布，它确实支持 Scala 2.11。 https://github.com/twitter/scalding/releases

【解决方案2】：

来自google groups

We don't compile for 2.11.0 since its super hard/impossible to have code compatible from 2.9 -> 2.11.
We (at twitter) are still on 2.9.x for the moment so for now we can only support up to the 2.10.x scala's. Hopefully this will change over the next few months.

此外，当前的 scalding 版本（0.12）仅与 scala 2.10（maven）兼容

正如@Travis 在评论中提到的，Scala 版本 2.11 的 Scalding 可在 scalding 的开发分支中使用 (github)

【讨论】：

我可以取消注释这一行吗：//scalaVersion := "2.10.4" 和前面的注释行？
请注意，该信息有点过时了——Twitter 几个月前迁移到 Scala 2.10，现在 Scalding 的 develop 分支提供 2.11 支持。
