Question

我正在尝试迁移一个我在Play上开始的小项目！ 2.2到2.5。但是，我遇到了Ebeans的问题，以及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会将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.*"]

我有什么遗失的吗？我使用IDEA创建投影并使用IDEA Scale插件1.5.4运行它。

[编辑：] 我还尝试在 stb-plugin 之前插入 sbt-play-ebean addSbtPlugin 。但是，这会产生以下错误：

[编辑2：]

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

我想我错过了＆＃39; javaEbean＆＃39;仍然在图书馆的依赖，这可能是原因。但是，删除它不会提供迁移警告，但会出现与上面关于ClassNotFound的编辑类似的异常：

Answer 1

您需要将其从依赖项中删除。将库依赖项更改为：

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

迁移到Play 2.5
