java - Maven：cvc-complex-type.2.4.a：发现以元素“插件”开头的无效内容

问题描述

我对 Maven pom.xml 配置不是很好。

对于 Corda (Blockchain) Bootcamp 示例，我正在尝试配置一个 Eclipse 项目以与 Java 和 Kotlin 一起使用，但我面临以下错误消息：

cvc-complex-type.2.4.a: Invalid content was found starting with element 'plugin'. 
One of '{

}' is expected.

这是整个 pom.xml 内容

我究竟做错了什么？

我是在这个 Baeldung 帖子中这样做的：

它有更多的问题信息。其中一些我通过使用<pluginManagement>标签解决了
