Grails - NEGOTIATE身份验证错误：未提供有效凭据

Question

错误：

 [main] WARN org.apache.http.client.protocol.RequestProxyAuthentication - 
 NEGOTIATE authentication error: No valid credentials provided
 (Mechanism level: No valid credentials 
 provided (Mechanism level: Failed to find any Kerberos tgt))

我正在使用：

Grails 2.3.8
GGTS 3.5.1    
Groory 2.1.9
Java 1.7

当我要在BuildConfig.groovy中更改

时

grails.project.dependency.resolution = {

        plugins {    
          // EasyGrid plugin http://grails.org/plugin/easygrid      
            compile ":easygrid:1.6.2"       
            // For minimum functionality you need: jquery-ui and the export plugins.        
            // Export Plugin http://grails.org/plugin/export        
            compile ":export:1.5"       
            // jQuery UI Plugin http://grails.org/plugin/jquery-ui      
            compile":jquery-ui:1.10.3"      
            // For google visualization you also need google-visualization      
            // Google Visualization API Plugin
           //  http://grails.org/plugin/google-visualization    
            compile":google-visualization:0.7"
       }
}

执行时会出现错误，如 -

Error |
Resolve error obtaining dependencies: Failed to read artifact descriptor for 
org.grails.plugins:easygrid:zip:1.6.2 (Use --stacktrace to see the full trace)**
