我知道这个问题已被多次询问（和回答），但现有的答案并没有解决我的问题。
我正按照DataStax spark-cassandra-connector
尝试构建this tutorial（标记v1.5.0-M3）./sbt/sbt assembly
但我收到以下错误

我读过的任何建议答案（例如this one）都是指build.sbt文件中所需的更改，但在我的情况下，我没有这样的文件。在project目录中我有
.
├── BuildUtil.scala
├── CassandraSparkBuild.scala
├── Publish.scala
├── Settings.scala
├── SparkInstaller.scala
├── Versions.scala
├── build.properties
├── plugins.sbt
├── project
└── target
2 directories, 8 files
所以我不知道要编辑哪些文件以及需要编辑哪些文件。我在OSX上并安装了以下版本
如果我关注the instruction here并为Scala 2.11构建，我会收到以下提示

如果查看SBT教程，您会发现project/*.scala文件等同于根目录中的*.sbt文件。这就是您需要进行更改的地方（具体来说，在CassandraSparkBuild.scala中）。
问题在于传递依赖关系中存在两个版本的Netty，而SBT没有注意到这一点，因为组ID不同：3.2.2为org.jboss.netty，3.8为io.netty。找到他们来自哪里（使用例如https://github.com/jrudolph/sbt-dependency-graph）并排除旧版本（并希望没有任何中断）。
