播放框架編譯錯誤：預期}但EOF發現

Question

當我嘗試編譯我的遊戲框架2.4的項目，我收到此錯誤：

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

這似乎表明，我卻辜負了我的牙套。但是，大括號實際上是正確匹配的，並且即使添加了額外（任意數量）的大括號大括號時，錯誤仍然存​​在。

我已經嘗試過「激活清潔」。

這裏是我的Application.java：

package controllers; 

import model.UserAccountManager; 
import play.data.Form; 
import play.libs.Json;

public class Application extends Controller { 

    public Result index() { 
     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))); 
    } 

    public Result login(String message) { 
     if (validSessionIsActive()) return index(); 
     if (message == null) message = ""; 
     return ok(views.html.loginpage.render(Form.form(Credentials.class), message)); 
    } 

    public Result logout() {

錯誤信息是混亂的，但問題是在testRegister方法。 render呼叫未正確關閉。

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

應該

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

錯誤消息可能是某種東西的Scala彈出。
