如何解决此问题？

由于gwt maven插件已升级到2.4.0版，因此很可能此特定快照不再存在

尝试将依赖项版本锁定为类似的版本，即1.3.1：

<dependencyManagement>
  <dependency>
      <artifactId>gwt-maven-plugin</artifactId>
      <groupId>org.codehaus.mojo</groupId>
      <version>1.3.1</version>
  </dependency>
</dependencyManagement> 

GWTMaven插件
org.codehaus.mojo
1.3.1

您应该在pluginManagement块中定义gwt maven插件，而不是在build区域中定义。据我所知，gwt maven插件将被其他插件使用，否则我无法理解您的输出。此外，永远不要依赖于插件的快照版本。修复插件的版本，以在构建中获得可实现的结果。最后但并非最不重要的一点是，开始使用存储库管理器（Artifactory、Archive、Nexus）来消除pom中的存储库定义。让生活更美好。

关于前面的答案：我不认为有理由将

gwt maven插件

依赖项放在

pluginManagement

中，除非它是在您的父POM中定义的。即使在这篇文章中也没有所谓的

pluginManagement

很明显，您使用的是最新版本的Vaadin（6.7.0），因此旧插件无法与之配合使用。试试这些：

• 最重要的是：将vaadin maven插件更改为1.0.2
• 将gwt maven插件的版本更改为2.3.0-1
• 将gwt用户的依赖项版本更改为2.3.0

如果上述修复无法工作，请尝试通过调用以下命令创建新的Vaadin项目：

mvn archetype:generate -DarchetypeGroupId=com.vaadin -DarchetypeArtifactId=vaadin-archetype-clean -DarchetypeVersion=LATEST -DgroupId=com.example -DartifactId=exampleArtifact -Dversion=1.0 -Dpackaging=war

并将POM结构和插件版本与您自己的进行比较。

只是想指出，我遇到了这个问题，使用的是

vaadin maven plugin

1.0.1，它指的是不再存在的其他插件的快照版本。将版本号更改为1.0.2修复了我的问题。

mvn archetype:generate -DarchetypeGroupId=com.vaadin -DarchetypeArtifactId=vaadin-archetype-clean -DarchetypeVersion=LATEST -DgroupId=com.example -DartifactId=exampleArtifact -Dversion=1.0 -Dpackaging=war
