Question

我有一个基于Gradle的多模块Google App Engine（GAE）项目，该项目最初来自https://github.com/GoogleCloudPlatform/appengine-modules-sample-java。

该项目具有App Engine的Cloud Endpoints，我将其迁移到 Cloud Endpoints Framework （＆＃34;云端点版本2＆＃34;）。我跟着https://cloud.google.com/endpoints/docs/frameworks/java/required_files，这意味着我改变了这些：

的build.gradle

+       compile 'com.google.endpoints:endpoints-framework-auth:1.0.0-beta.10'
+       compile 'com.google.endpoints:endpoints-management-control-appengine:1.0.0-beta.10'

应用服务引擎-web.xml中

+       <env-variables>
+               <env-var name="ENDPOINTS_SERVICE_NAME" value="myproject.appspot.com" />
+       </env-variables>

的web.xml

+       <!-- Endpoints service config from service management -->
+       <filter>
+               <filter-name>endpoints-api-configuration</filter-name>
+               <filter-class>com.google.api.control.ServiceManagementConfigFilter</filter-class>
+       </filter>
+       <filter-mapping>
+               <filter-name>endpoints-api-configuration</filter-name>
+               <servlet-name>api</servlet-name>
+       </filter-mapping>
+
+       <!-- Endpoints logging and monitoring -->
+       <filter>
+               <filter-name>endpoints-api-controller</filter-name>
+               <filter-class>com.google.api.control.extensions.appengine.GoogleAppEngineControlFilter</filter-class>
+               <init-param>
+                       <param-name>endpoints.projectId</param-name>
+                       <param-value>myproject</param-value>
+               </init-param>
+               <init-param>
+                       <param-name>endpoints.serviceName</param-name>
+                       <param-value>myproject.appspot.com</param-value>
+               </init-param>
+       </filter>
+       <filter-mapping>
+               <filter-name>endpoints-api-controller</filter-name>
+               <servlet-name>api</servlet-name>
+       </filter-mapping>

（我已完成https://cloud.google.com/appengine/docs/java/endpoints/migrating中的部分，我将不在此讨论）

但是在尝试使用＆＃34; gradle appengineRun＆＃34;

尝试运行它时遇到此错误

我该如何解决这个问题？

Answer 1

我添加了一个环境变量：

key = ENDPOINTS_SERVICE_NAME 
value = myproject.appspot.com

（here how to add an enviroment variable）

Here是解释此标记含义的Google文档：

可选。 appengine-web.xml文件可以定义环境变量   在应用程序运行时设置。

   为避免与您的本地环境发生冲突，请   开发服务器不会基于此设置环境变量   文件，并要求本地环境具有这些变量   已设置为匹配值。

迁移到Google Cloud Endpoints Framework for Java
