Playframework 为什么从2.2.1迁移到2.3.1时会出现未解析的依赖项？

您好，我已尝试将我的play项目迁移到较新版本，但产生了一些无法修复的错误。我试着像play framework站点上显示的那样，从play 2.2.x迁移到play 2.3.x

1. Waiting for source changes... (press enter to interrupt)

我的build.sbt看起来像：

name := "error"

version := "0.1.1"

scalaVersion := "2.11.1"

doc in Compile <<= target.map(_ / "none")

libraryDependencies ++= Seq(
  javaJdbc,
  javaEbean,
  cache
)
libraryDependencies += "mysql" % "mysql-connector-java" % "5.1.24"
libraryDependencies += "org.fusesource.scalate" % "scalate-core" % "1.5.3"
libraryDependencies += "net.sf.opencsv" % "opencsv" % "2.3"
libraryDependencies += "com.typesafe" %% "play-plugins-mailer" % "2.2.0"

我认为问题出在

project/plugins.sbt

中，您错过了Typesafe版本存储库（解析器）。添加以下内容并重新开始

resolvers += "Typesafe repository" at "http://repo.typesafe.com/typesafe/releases/"

还有快捷方式（如果你想成为极客）：

我认为您可能需要添加：

lazy val root=（文件中的项目（“.”）。enablePlugins（PlayJava）

请参阅

resolvers += "Typesafe repository" at "http://repo.typesafe.com/typesafe/releases/"

resolvers += Resolver.typesafeRepo("releases")
