无法建立maven Vaadin 11初学者包，缺少依赖？

Question

我不能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，它提供了一个@Helper注释。我试图在pom.xml中添加依赖项，但没有运气。

这是Maven的日志：

当我在pom中添加依赖项时：

[INFO] ------------------------------------------------------------------------
[INFO] BUILD FAILURE

这是pom.xml部分，其中添加了依赖项：

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

有谁知道如何修复依赖？

Answer 1

您可以从代码中删除对@Helper注释的所有引用。它仅用于我们自己的内部测试，用于验证教程代码的编译。

我已经创建了关于修复教程和/或代码的a ticket，以便将来不会出现这个问题。
