我使用activator new simple play-scala命令创建了一个新项目。simple是我的项目名称。我想将此项目导入到我的 Eclipse（ScalaIDE）中，所以我使用activator eclipse了命令，但它显示了以下异常

[error] Not a valid command: eclipse (similar: help, alias)
 [error] Not a valid project ID: eclipse 
[error] Expected ':' [error] Not a valid key: eclipse (similar: deliver, licenses, clean) 
[error] eclipse [error]

对于这个错误，我添加了addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "4.0.0") https://www.playframework.com/documentation/2.4.x/IDE命令simple/project/plugins.sbt它解决了上述错误，但它显示了错误

sbt 版本：=0.13.8 scalaVersion： =2​​.11.6

我也试过addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "3.0.0")这个它成功地构建了eclipse项目，但它显示了错误

应用程序.scala

object index is not a member of package views.html

首先，ScalaIDE 仍处于开发阶段，还不如 Eclipse JDT 稳定。据我所知，尤其是 Play 支持仍然存在一些问题。但是，使用 activator/sbt，您可以毫无问题地编译、测试和运行您的 Play 代码。

但是让我们看看你的错误信息。我假设你想摆脱它们。;)

  1. 使用addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "3.0.0"). 4.0.0 尚未最终/可用。

  2. object index is not a member of package views.html. 看看这个问题的答案。目前还没有通用的解决方案。但是，对我来说，它可以在项目的构建路径中包含另外两个源文件夹：

    target/scala-2.11/routes/main
target/scala-2.11/twirl/main

  3. type Html is not a member of package play.api.templates等等。我不知道如何解决这个问题。但是，如果您在进行更改后关闭 html 文件，然后进行干净的构建，所有错误消息都将消失。

更新：Scala IDE 用户组中有关于问题 3 的讨论。但是，还没有解决方案。

我有同样的问题。将 sbteclipse 插件版本设置为更早的版本是行不通的，因为 sbt 坚决拒绝它，并为 4.0 版本丢弃它，这是不可用的。Sbt 很痛苦......甚至他们的网站也没有关于这个问题的文档，从它的外观来看，它至少有一年的历史？
