“对象索引不是包view.html”的成员“当在scala ide中打开scala播放项目时 [英] "object index is not a member of package views.html" when opening scala play project in scala ide

问题描述

我创建了一个播放项目，播放2.3.7

在项目目录中，我运行激活器并运行 eclipse 命令生成eclipse项目文件。

当我去eclipse（我正在使用Scala IDE from typesafe Build id：4.0.0-vfinal -20150119-1023-Typesafe，我的Application.scala文件有一个错误：

 对象索引不是包的成员views.html 
  

我的设置有什么不好吗？当我执行在激活控制台提示下运行。

谢谢！

：添加代码

 包控制器
 
 import play.api._ 
 import play。 api.mvc._ 
 
对象应用程序扩展Controller {
 
 def index = Action {
 Ok（views.html.index（your new application ready ））
} 
 
} 
  

错误在好吧..

视图中有一个名为index.scala.html的文件，当我从激活器运行时，应用程序运行文件。

$ b $在Play 2.4.x中添加视图后，有时候，IntelliJ IDEA有时会感到困惑，绝对拒绝建立。甚至重建项目失败：

这仍然发生在时间在IDEA 15中。如果这样，命令行提供了最快，最可靠的修复：

sbt clean ; sbt compile

就是这样！ IDEA现在将按预期编译项目。

更新：

在极少数情况下， sbt compile 在命令行上成功完成，但IntelliJ IDEA 15仍然给出相同的对象x不是成员错误，那么这解决了IDEA的困惑：

文件菜单：

I've created a play project with play 2.3.7

In the project directory, I ran activator and ran the eclipse command to generate eclipse project files.

When I go to eclipse (I'm using the Scala IDE from typesafe Build id: 4.0.0-vfinal-20150119-1023-Typesafe , there is an error in my Application.scala file:

object index is not a member of package views.html

Is there something amiss with my setup? The app runs fine when I execute run at the activation console prompt.

Thanks!

EDIT: Added code

package controllers

import play.api._
import play.api.mvc._

object Application extends Controller {

  def index = Action {
    Ok(views.html.index("Your new application is ready."))
  }

} 

The error is on the 'Ok..' line.

There is a file in views called index.scala.html, and the app runs file when I run it from activator..

解决方案

Occasionally after adding a view in Play 2.4.x, IntelliJ IDEA sometimes gets confused and absolutely refuses to build. Even rebuild Project fails:

This still happens from time-to-time in IDEA 15. And when it does, the command line provides the quickest, most-reliable fix:

sbt clean; sbt compile

That's it! IDEA will now compile the project as expected.

Update:

In the rare case that sbt compile completed successfully on the command line, but IntelliJ IDEA 15 still gives the same "object x is not a member" error, then this has solved IDEA's confusion:
