播放框架编译错误：预期}但EOF发现

Question

当我尝试编译我的游戏框架2.4的项目，我收到此错误：

`}' expected but eof found. 
In /Users/dylhunn/Documents/workspace/my-project/app/controllers/Application.java 

这似乎表明，我却辜负了我的牙套。但是，大括号实际上是正确匹配的，并且即使添加了额外（任意数量）的大括号大括号时，错误仍然存​​在。

我已经尝试过“激活清洁”。

这里是我的Application.java：

package controllers; 

import model.UserAccountManager;

     if (validSessionIsActive()) return harmonizepage(); 
     else return landing(); 
    } 

    public Result about() { 
     Content html = views.html.auxtemplate.render("title", "content"); 
     return ok(html); 
    } 

    public Result contact() { 
     Content html = views.html.auxtemplate.render("title", "content"); 
     return ok(html); 
    } 

    public Result landing() { 
     return ok(views.html.landing.render(form(Credentials.class))); 
    }

错误信息是混乱的，但问题是在testRegister方法。 render呼叫未正确关闭。

return ok(views.html.signuppage.render(Form.form(UserData.class)); 

应该

return ok(views.html.signuppage.render(Form.form(UserData.class))); 

错误消息可能是某种东西的Scala弹出。
