maven - 无法构建 Maven Vaadin 11 入门包，缺少依赖项？

Question

我无法像文档教程部分中提到的那样构建 maven Vaadin 11 入门包。似乎缺少一个包，它提供了 @Helper 注释。我尝试在 pom.xml 中添加依赖项，但没有成功。

这是来自 Maven 的日志:

当我在 pom 中添加依赖项时:

这是 pom.xml 部分，其中包含我添加的依赖项:

  <dependency>
      <groupId>com.vaadin</groupId>
      <artifactId>flow-documentation-parent</artifactId>
      <version>1.1-SNAPSHOT</version>
      <scope>compile</scope>
    </dependency>
  </dependencies>

有人知道如何修复依赖关系吗？

Answer 1

您可以从代码中删除对 @Helper 注释的所有引用。它仅由我们自己的内部测试使用，以验证教程代码的编译。

我创建了a ticket关于修复教程和/或代码，以便将来不再出现问题。
