Question

我正在尝试让我的Android应用程序使用与我的gwt应用程序相同的requestfactories与服务器进行通信。我使用maven来构建android应用程序和gwt应用程序。在android上进行请求工厂调用时，我得到了异常：

08-05 23:04:33.501: ERROR/AndroidRuntime(22839): java.lang.RuntimeException: No token manifest found.  Did the RequestFactory annotation processor run? Check classpath for META-INF/requestFactory/typeTokens file and ensure that your proxy types are compiled with the requestfactory-apt.jar on javac's classpath.

我使用java 1.6进行构建。我的gwt版本是2.4（rc1）。我尝试使用maven-processor-plugin并导入requestfactory-apt。但不知何故，maven处理器插件似乎找不到处理器。不确定配置应该如何。

我有：

    <plugin>
      <groupId>org.bsc.maven</groupId>
      <artifactId>maven-processor-plugin</artifactId>
      <version>2.0.4-SNAPSHOT</version>
       <executions>
        <execution>
           <id>process</id>
          <goals>
            <goal>process</goal>
          </goals>
          <phase>generate-sources</phase> 
          <<configuration>
            <processors>
               <processor>com.google.gwt.requestfactory-apt</processor>
            </processors> 
          </configuration>  
        </execution>
      </executions>
   </plugin>

注释文件夹在我的目标文件夹中创建，但它是空的。有谁知道问题可能是什么？您需要哪些其他信息？

更新我将版本更改为2.0.3-SNAPSHOT。现在我明白了：

[INFO] Source directory: E:\Eclipse\Eclipse3.7\android\target\META-INF\requestFactory added
[INFO] javac option: -cp
[INFO] javac option: C:\profiles\....
[INFO] javac option: -proc:only
[INFO] javac option: -processor
[INFO] javac option: com.google.web.bindery.requestfactory.apt.RfApt
[INFO] javac option: -d
[INFO] javac option: E:\Eclipse\Eclipse3.7\android\target\classes
[INFO] javac option: -s
[INFO] javac option: E:\Eclipse\Eclipse3.7\android\target\META-INF\requestFactory

但此文件夹中没有文件。当我添加：

<compilerArguments>
             -Averbose=true</compilerArguments>   
          </configuration>

到我的pom。我收到错误消息：

diagnostic warning: The following options were not recognized by any processor: '[verbose]'

现在我再次陷入困境： - /

Answer 1

处理器类的名称为com.google.web.bindery.requestfactory.apt.RfApt，但应自动发现，而无需显式的<configuration>部分。

此外，示例代码中有<<configuration>，是否存在复制粘贴错误？

Answer 2

这可能对你有帮助， RequestFactoryInterfaceValidation

尝试使用RequestFactory ValidationTool

用Maven进行GWT中的注释处理
