播放框架:找不到:价值参数 [英] play framework: not found: value params

问题描述

昨天我在Play 2.1.1应用程序中遇到了一些路由问题，并删除了目标文件夹的内容以强制Play重新编译所有内容(可能是一个愚蠢的主意).

Yesterday I had some problems with routes in my Play 2.1.1 app and deleted the contents of the target folder to force Play to recompile everything (probably a dumb idea).

现在我在Eclipse中遇到很多错误:

Now I get a bunch of errors in Eclipse:

too many arguments for method apply: (name: String, constraint: String)play.core.DynamicPart in object DynamicPart  routes_routing.scala    /myapp/target/scala-2.10/src_managed/main   line 44 Scala Problem

经过一些google和stackoverflow研究，我尝试在该项目上执行play clean compile.那个有效.我也可以启动该应用程序，它似乎可以正常工作.

After some google and stackoverflow research I tried to perform a play clean compile on the project. That works. I can also start the application and it seems to work properly.

清理后，我在Eclipse中尝试了Refresh.那不会改变任何东西.错误不会消失.

After the clean I tried a Refresh in Eclipse. That does not change anything. The errors won't go away.

有什么建议吗?

谢谢！

推荐答案

您需要重新生成eclipse项目

You need to regenerate the eclipse project

1. 开始播放

生成Eclipse项目(在Play控制台中执行此步骤)

Generate eclipse project (perform this step inside play console)

eclipse with-source=true

刷新您的日食项目

Refresh your eclipse project

您不必在每次进行重要更改时都删除eclipse项目:-)

You don't have to delete the eclipse project every time you make important changes :-)
