activator eclipse命令显示sgt . resolveexception

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。我想把这个项目导入到我的eclipse(ScalaIDE)中，所以我使用了activator eclipse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，我在simple/project/plugins.sbt中添加了addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "4.0.0") https://www.playframework.com/documentation/2.4.x/IDE命令，它解决了上面提到的错误，但它显示错误

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

Applications.scala

object index is not a member of package views.html

index.scala.html, main.scala.html

Multiple annotations found at this line:
- type Html is not a member of package play.api.templates
- type Html is not a member of package play.api.templates
- type Html is not a member of package play.api.templates
- object HtmlFormat is not a member of package
play.api.templates

首先，ScalaIDE仍在开发中，还没有Eclipse JDT那么稳定。据我所知，特别是Play支持还存在一些问题。然而，使用activator/sbt，你可以编译、测试和运行你的Play代码，而不会出现任何问题。

但是让我们看看你的错误消息。我猜你是想摆脱他们。;)

使用addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "3.0.0")。4.0.0还不是最终版/可用版。
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。然而，对我来说，在项目的构建路径中包含两个以上的源文件夹是有效的:
```
target/scala-2.11/routes/main
target/scala-2.11/twirl/main
```
type Html is not a member of package play.api.templates等。我不知道怎么才能解决这个问题。但是如果你在修改后关闭html文件，然后做一个干净的构建，所有的错误信息都会消失。

更新:在Scala IDE用户组中有一个关于问题3的讨论。但是，目前还没有解决方案。

我有同样的问题。将sbteclipse插件版本设置为较早的版本不起作用，因为sbt坚决拒绝它，并在4.0版本中丢弃它，而4.0版本不可用。这是一种痛苦……甚至他们的网站上也没有关于这个问题的文档，从表面上看，这个问题至少有一年了。
