Migrating to Play 2.5

Question

我正在尝试迁移我在Play上启动的一个小项目！2.2至2.5。然而，我遇到了Ebeans的问题，并将Ebeans迁移到一个单独的模块。

因此，我尝试启动一个干净的项目，并根据文档添加EBean，但我仍然得到以下消息：

[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.

我的版本.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" )  

（注意，Idea显示PlayEbean为红色，因为它不知道模块？）

插件.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")

内部版本属性：

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.*"]

我有什么东西不见了吗？我用IDEA创建投影，并用IDEA Scale插件1.5.4运行它。

[编辑：]我还尝试在stb插件之前对接sbt play ebeanaddSbtPlugin。然而，这会产生以下错误：

[编辑2:]

libraryDependencies ++= Seq( javaJdbc , javaEbean , cache , javaWs )

我想我错过了"javaEbean"仍在库Dependencies中的事实，这可能是原因。然而，删除它并不会发出迁移警告，而是会出现类似于上面关于ClassNotFound:的编辑中的异常

您需要将其从依赖项中删除。将您的库依赖项更改为：

libraryDependencies ++= Seq( javaJdbc , cache , javaWs )
