激活器 eclipse 命令显示 sbt.ResolveException

Question

我已经使用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，所以我使用了activator eclipse 命令，但它显示如下例外

[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

Answer 1

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。

但是让我们看看您的错误消息。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this question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。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，所有错误消息都会消失。

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

Answer 2

我也有同样的问题。 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，从表面上看，它至少有一年的历史了？
