无法构建 Maven Vaadin 11 入门包，缺少依赖项？

Question

我无法像文档的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，但没有成功。

这是 Maven 的日志：

当我在 pom 中添加依赖时：

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>

这里是link教程：https://vaadin.com/docs/v11/flow/introduction/tutorial-get-started.html

有谁知道如何修复依赖关系？

Answer 1

您可以从代码中删除对 @Helper 注释的所有引用。它仅供我们自己的内部测试使用，用于验证教程代码是否编译。

我已经创建了 a ticket 来修复教程 and/or 代码，这样以后就不会出现问题了。
