我有一个相当大的 GWT 应用程序，我想试试 gwteventservice。为此，我从Maven Repository Page获取了 1.2.1 版本的依赖项：

<dependency>
    <groupId>de.novanic.gwteventservice</groupId>
    <artifactId>eventservice</artifactId>
    <version>1.2.1</version>
</dependency>

在将它添加到我pom.xml的 Maven 依赖项并对我的项目进行干净构建之后，突然出现了一大堆编译器错误。
我从 Eclipse 的“问题”选项卡中复制了相关消息（每一行都是一个单独的条目）：

有趣的是，这些只显示在代码的客户端。如果没有添加依赖项，我的应用程序编译得很好。

我的环境：

  • Java 1.7.0_55
  • GWT 2.6.0
  • Maven 3.3.1

到目前为止我没有成功的尝试：

  • 在我的pom.xml
  • Eclipse 建议将 Quick-Fix 添加gwt-user.jar到我的构建路径中
  • 将依赖项添加gwt-user到我的pom.xml
  • 将相关的外部 jar 直接添加到我的构建路径中（这是唯一有效的方法，但我真的不喜欢这个解决方案......我宁愿把所有东西都放在我的pom.xml.

所以问题是：

  • 为什么添加依赖项会破坏我的项目和
  • 我怎样才能解决这个问题？

如果没有其他帮助，我可能会考虑gwt-comet。

gwteventservice如您在此处看到的，依赖于 gwt 2.1.0 。我认为您不能将它与 GWT 2.6.0 一起使用。

尝试排除从事件服务传递继承的依赖项。

<dependencies>
  ....
  <dependency>
     <groupId>de.novanic.gwteventservice</groupId>
     <artifactId>eventservice</artifactId>
     <version>1.2.1</version>
     <exclusions>
        <exclusion>
           <artifactId>gwt-servlet</artifactId>
           <groupId>com.google.gwt</groupId>
        </exclusion>
        <exclusion>
           <artifactId>gwt-user</artifactId>
           <groupId>com.google.gwt</groupId>
        </exclusion>
     </exclusion>
  </dependency>
  <dependency>
      <artifactId>gwt-user</artifactId>
      <groupId>com.google.gwt</groupId>
      <version>2.6.0</version>
  </dependency>
  <dependency>
      <artifactId>gwt-servlet</artifactId>
      <groupId>com.google.gwt</groupId>
      <version>2.6.0</version>
  </dependency>
  ....
</dependencies>

但是您需要为它们提供依赖项（即使您不需要它们），同时eventservice会寻找它们。
