迁移到 Play 2.5
Migrating to Play 2.5
我正在尝试迁移我在 Play 上开始的一个小项目！ 2.2 至 2.5。但是，我 运行 正在研究 Ebeans 的问题，并将 Ebeans 迁移到一个单独的模块。
所以我尝试启动一个干净的项目，并根据文档添加 EBeans，但我仍然收到以下消息：
[info] Loading project definition from /Users/user/Documents/Java/xyz/project
Play ebean module has been replaced with an external Play ebean plugin.
See https://playframework.com/documentation/2.4.x/Migration24 for details.
我的build.sbt:
name := "y2kbooking"
version := "1.0"
lazy val `y2kbooking` = (project in file(".")).enablePlugins(PlayJava, PlayEbean)
scalaVersion := "2.11.6"
libraryDependencies ++= Seq( javaJdbc , javaEbean , cache , javaWs )
unmanagedResourceDirectories in Test <+= baseDirectory ( _ /"target/web/public/test" )
（请注意，Idea 将 PlayEbean 显示为红色，因为它不知道该模块？）
Plugins.sbt:
logLevel := Level.Warn
resolvers += "Typesafe repository" at "http://repo.typesafe.com/typesafe/releases/"
addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.4.0")
addSbtPlugin("com.typesafe.sbt" % "sbt-play-ebean" % "1.0.0")
build.properties:
sbt.version=0.13.8
application.conf:
db.default.driver=org.h2.Driver
db.default.url="jdbc:h2:mem:play"
db.default.user=sa
db.default.password="defaultlogonpassword"
ebean.default= ["models.*"]
有什么我想念的吗？
我使用 IDEA 创建投影，并使用 IDEA Scale 插件 1.5.4 运行 创建它。
[编辑：]
我还尝试在 stb-plugin 之前添加 sbt-play-ebean addSbtPlugin。然而，这会产生以下错误：

libraryDependencies ++= Seq( javaJdbc , javaEbean , cache , javaWs )
我想我错过了 'javaEbean' 仍然在 libraryDependencies 中的事实，这可能是原因。但是，删除它不会给出迁移警告，但会出现与上面关于 ClassNotFound 的编辑中类似的异常：
