谷歌云端点与maven

我正在尝试谷歌云端点上的gae。我正在尝试整合它的maven。我发现这个maven插件这样做： http://code.google.com/p/maven-endpoint-plugin/谷歌云端点与maven

我能够定义我的api并产生api。当它部署在应用程序引擎上时，我可以调用我的api。但是，当我尝试localy称它为调试，我得到以下异常：

而且我也无法生成客户端库（执行MVN编译或与谷歌的Eclipse插件）

有没有人成功地集成谷歌云enpoints与Maven： - 生成的客户端库 - 本地测试 - 部署到App Engine和得到它的工作（这是唯一的一步，我设法工作）

如果你依赖于 com.google.appengine AppEngine上的端点 1.7 .7 com.google.appengine appengine-api-1.0-sdk 1.7.7 的javax.servlet servlet的API 2.5 提供

，你使用谷歌应用程序引擎Maven插件1.7。7：

 <plugin> 
      <groupId>com.google.appengine</groupId> 
      <artifactId>appengine-maven-plugin</artifactId> 
      <version>1.7.7</version> 
      <executions> 
       <execution> 
        <phase>compile</phase> 
        <goals> 
         <goal>endpoints_get_discovery_doc</goal> 
         <!--goal>endpoints_get_client_lib</goal--> 
        </goals> 
       </execution> 
      </executions> 
      <configuration> 
       <serviceClassNames>YOURENDPOINTSCLASSES(comma separated)</serviceClassNames> 
      </configuration> 
     </plugin>

你是好去与这些2个球： enpoints_get_discovery_doc 和 endpoints_get_client_lib

感谢您的提示。我决定放弃云端点。它不支持multipart/form-data，我需要一些服务来处理这种类型的内容。我决定使用球衣。 – 2013-04-15 10:14:54

您可以发布您的pom.xml。

提前......你不能用maven插件创建客户端库。它只是创建你的api文件。您必须使用SDK提供的端点命令工具在外部创建它们。

谢谢您的回答。我已将我的pom.xml文件添加到问题中。 – 2013-03-07 15:48:41

我终于可以在本地端点服务器上运行我的端点了。这个例外与maven插件无关。我没有正确使用enpoint注释，这就是为什么我一直有这个例外。我无法弄清楚为什么它在gae生产服务器上工作。这里的错误：我写

public void deleteProject(@Named Long projectId) { 
    projectManager.deleteProject(projectId); 
}

，而不是写

public void deleteProject(@Named("id") Long projectId) { 
    projectManager.deleteProject(projectId); 
}

我忘了定义名称参数为“@Named”标注为我的一些方法。

添加此

<dependency> 
    <groupId>com.google.appengine</groupId> 
    <artifactId>appengine-endpoints</artifactId> 
    <version>1.7.6</version> 
    <scope>runtime</scope> 
</dependency>

到Maven的依赖（我使用的1.7.6版本，当然）
