运行finch/finagle应用程序时的AbstractMethodError

Question

我试图运行我的应用程序，我得到了以下错误：

java.lang.AbstractMethodError: com.twitter.finagle.stats.MetricsStatsReceiver

我的代码是：

object Main extends TwitterServer {

  implicit val objectMapper: ObjectMapper = ObjectProvider.objectMapper

  val appConf = ConfigFactory.load()

  def main(): Unit = {
    statsReceiver.counter("posts")
    statsReceiver.counter("login")
    // configuration
    val port = appConf.getInt("8090")
    val db = new CommDb()
    val service = Api.makeService(db)
val server = Http.serve(":8080", service) //creates service

  def close(): Future[Unit] = {
    Await.ready(server.close())
  }
    Await.ready(server)
  }
}

它可能是一个bug，所以我应该使用哪个版本的库，或者我可以切换到一个更稳定的web服务库。

我看到其他人也有同样的问题：

正如Alexey在他的评论中提到的，这是一个依赖不匹配的问题。sbt依赖关系图是确保所有库都依赖于同一个版本的有用工具。
