Question

尝试使用maven构建GWT项目时出现此错误：

您的项目声明对gwt-user 2.6.0的依赖。这个插件是设计用于至少gwt版本2.7.0

我发现使用com.google.gwt.eventbinder下载了gwt-user 2.6.0。我如何使用gwt-user 2.7.0而不是2.6.0强制com.google.gwt.eventbinder？

奇怪的是，在我做之前，构建工作正在进行中。

这是我的pom.xml

解决方案1 

问题是eventbinder依赖于gwt-user工件。它默认使用2.6.0，您可以使用此命令查看它。

mvn dependency:tree

如果您将此依赖关系块添加到您的pom;

<dependency>
   <groupId>com.google.gwt</groupId>
   <artifactId>gwt-user</artifactId>
   <version>2.7.0</version>
</dependency>

看起来像这样......

这意味着您的项目将始终拥有gwt-user 2.7.0，如果版本兼容性一切正常或您的问题将得到解决，我还没有测试过。

解决方案2 感谢@Thomas Broyer的评论，我们可以强制eventbinder使用2.7.0 gwt-user或任何gwt依赖。如果我们只是将这种依赖管理添加到我们的pom

<dependencyManagement>
 <dependencies>
  <dependency>
    <groupId>com.google.gwt</groupId>
    <artifactId>gwt</artifactId>
    <version>2.7.0</version>
    <type>pom</type>
    <scope>import</scope>
  </dependency>
 </dependencies>
</dependencyManagement>

结果：

如何强制依赖项包含具有特定版本号的工件
