java - org.apache.maven.plugins :maven-surefire-plugin is missing 的“build.plugins.plugin.version”

Question

尝试熟悉 Maven 并参加在线类(class)，但陷入困境......感谢提供的任何帮助。

我正在运行站点阶段，虽然它已完成并且我能够在浏览器中实际查看index.html，但我在此过程中遇到了很多错误，具体来说:

org.apache.maven.plugins 的“build.plugins.plugin.version”:maven-surefire-plugin 丢失

不知道为什么会产生此错误。正如您在下面看到的，我在依赖项和插件中都有该版本。我尝试了网站上能找到的所有内容。为什么它认为版本丢失？有什么想法如何解决吗？预先感谢您的帮助!

Answer 1

从 <dependencies> 中删除以下 2 个依赖项应该修复所有错误。这两个是 Maven 插件，<dependencies> 中不需要部分。

当您将这 2 个作为依赖项包含时，maven-project-info-reports-plugin正在尝试为这两个插件生成依赖关系报告，但失败了。因此您会看到这些错误。

    <dependency>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <version>2.22.2</version>
    </dependency>
