Question

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

中获取了版本1.2.1的依赖关系

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

将其添加到我的pom.xml，更新Maven依赖项并对项目进行干净构建后，突然出现了一大堆编译错误。
我复制了＆＃34; Problems＆＃34;中的相关消息。 Eclipse中的选项卡（每行是一个单独的条目）：

有趣的是，这些只会出现在代码的客户端上。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

到目前为止我尝试的内容没有成功：

在我的pom.xml
Eclipse建议使用Quick-Fix将gwt-user.jar添加到我的构建路径
将依赖关系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中（这是唯一可行的，但我真的不喜欢这个解决方案......我宁愿在我的pom.xml中拥有所有内容）

所以问题是：

为什么添加依赖项会破坏我的项目和
我该如何解决这个问题？

如果没有其他帮助，我可能会调查gwt-comet。

Answer 1

gwteventservice依赖于gwt 2.1.0，因为您可以看到here。我不认为你可以在GWT 2.6.0中使用它。

Answer 2

尝试从事件服务传递继承的排除依赖项。

<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关系（即使你不需要它们），而eventservice会寻找它们。

添加gwteventservice作为Maven依赖项中断项目
