我正在从Activator 2.3.x升级到2.4.x（最终升级到2.5.x）。作为此迁移的一部分，我不能再使用activator eclipse命令从Play应用程序生成Eclipse项目。
我在一个团队工作，其中一些团队使用IntelliJ。因此，我不能对每个项目进行这些更改，因为它对IntelliJ用户来说是不可用的，并且使用项目源进行版本化是不合适的。
我一直在关注these条款。以下是我到目前为止所采取的迁移步骤：
evolutionplugin=disabled更改为play.evolutions.enabled=false javaEbean libraryDependencies
C:\dev\.sbt\0.13 SBT_HOME=C:\dev\.sbt\0.13 %SBT_HOME%\bin添加到PATH PATH=...;%SBT_HOME%\bin; %SBT_HOME%创建'plugins'文件夹
- C:\dev\.sbt\0.13\plugins C:\dev\.sbt\0.13\plugins\plugins.sbt addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "4.0.0") %SBT_HOME%\conf\sbtopts以指定SBT插件目录：-sbt-dir C:/dev/.sbt/0.13/plugins %SBT_HOME%\conf\sbtopts以指定SBT启动目录：-sbt-boot C:/dev/.sbt/0.13/plugins/boot %SBT_HOME% 此时，我应该能够创建一个Eclipse项目，但它无法解析sbteclipse：

因此，您可以从上面列出的步骤中看到，我正在尝试允许Eclipse用户从Play服务创建项目。我下载了SBT，将其解压缩到我的dev文件夹，然后开始在那里进行全局更改。
C:\dev\.sbt\0.13\plugins\plugins.sbt的内容：
// Support Play in Eclipse
addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "4.0.0")
C:\dev\.sbt\0.13\sbteclipse.sbt的内容：

// Download Source and Javadocs with binaries
EclipseKeys.withSource := true
EclipseKeys.withJavadoc := true
// Compile the project before generating Eclipse files, so that generated .scala or .class files for views and routes are present
EclipseKeys.preTasks := Seq(compile in Compile)
// Java project. Don't expect Scala IDE
EclipseKeys.projectFlavor := EclipseProjectFlavor.Java
// Use .class files instead of generated .scala files for views and routes
EclipseKeys.createSrc := EclipseCreateSrc.ValueSet(EclipseCreateSrc.ManagedClasses, EclipseCreateSrc.ManagedResources)
C:\dev\.sbt\0.13\conf\sbtopts的内容：

项目位于C:\dev\eclipse\workspaces\company\project。在Cygwin中，我导航到该位置并执行sbt eclipse（或activator eclipse，其具有相同的结果），根据我的理解，这应该起作用。但是，就像我说的那样，我得到一个错误，但它不起作用。
有人可以帮我正确设置这个设置，以便我可以为Play服务创建Eclipse项目文件，并继续我快乐的lil迁移之旅吗？
我认为sbteclipse插件试图使用我的系统版本的scala，而不是插件指定的版本并在boot文件夹中提供。
答案 0 :(得分：0)
我最近从Play 2.4迁移到Play 2.5，并在this post中描述了整个过程。在another post中，您可以找到如何＆＃34; eclipcify＆＃34;该项目。
我没注意，你使用全局sbt设置。 对于全局sbt设置：
使用内容创建c：\ dev \ .sbt \ 0.13 \ plugins \ plugins.sbt：
//Support Play in Eclipse
addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "4.0.0")
使用内容创建C：\ dev \ .sbt \ sbteclipse.sbt：
import com.typesafe.sbteclipse.plugin.EclipsePlugin.EclipseKeys
EclipseKeys.preTasks := Seq(compile in Compile)
EclipseKeys.withSource := true
EclipseKeys.withJavadoc := true
// Java project. Don't expect Scala IDE
EclipseKeys.projectFlavor := EclipseProjectFlavor.Java
// Use .class files instead of generated .scala files for views and routes
EclipseKeys.createSrc := EclipseCreateSrc.ValueSet(EclipseCreateSrc.ManagedClasses, EclipseCreateSrc.ManagedResources)
注意：在我的情况下，而不是 dev 是我的用户根目录。
项目build.sbt：
import NativePackagerHelper._
name := """play-server-example"""
version := "1.0-SNAPSHOT"
lazy val root = (project in file(".")).enablePlugins(PlayJava)
scalaVersion := "2.11.8"
resolvers += "Local Maven Repository" at "file:///"+Path.userHome.absolutePath+"/.m2/repository"
libraryDependencies ++= Seq(javaJdbc, cache, javaWs)
注意：最初我使用scalaVersion：= 2.11.7，因为这是生成的值，但是对于测试我放了2.11.8。这适用于他们两个。
我没有更多的东西：没有sbt选项，只有sbt home在环境变量中（就像在我的帖子中一样）。
底线：我只做了第1,2,3项，以确保工作正常。
