添加 gwteventservice 作为 Maven 依赖中断项目

Question

我有一个相当大的 GWT 应用程序，我想试用 gwteventservice。为此，我从 Maven Repository Page:

中获取了 1.2.1 版本的依赖

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

将它添加到我的 pom.xml 后，更新 Maven 依赖项并清理我的项目，突然出现一大堆编译器错误。
我从 Eclipse 中的 "Problems" 选项卡复制了相关消息（每行都是一个单独的条目）：

有趣的是，这些只出现在代码的 客户端 上。如果没有添加依赖项，我的应用程序可以正常编译。

我的环境：

Java1.7.0_55
GWT 2.6.0
行家 3.3.1

到目前为止我试过什么都没有成功：

在我的 pom.xml
Eclipse 建议快速修复以将 gwt-user.jar 添加到我的构建路径
正在将依赖项 gwt-user 添加到我的 pom.xml
将相关的外部 jar 直接添加到我的构建路径（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并且
我该如何解决这个问题？

如果没有其他帮助，我可能会考虑 gwt-comet。

Answer 1

如您所见，

gwteventservice 依赖于 gwt 2.1.0 here。我认为您不能将它与 GWT 2.6.0 一起使用。

Answer 2

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>

但是你需要为它们提供依赖项（即使你不需要它们），而 eventservice 会寻找它们。
