1. BUG 场景

博主是使用 idea 的 spring Initializr 创建的 springboot 项目。
完成初步功能后进行 build 时出现 build failure 错误。
pox.xml 无修改过 <build> 标签内容。
完整的报错信息如下

3. 解决方案

因为第一条 [ERROR] 已经提示 使用默认的 maven-resources-plugin:3.2.0:resources 失败，所以第一反应是修改版本。
即在 springboot 项目中的 pox.xml 文件指定恰当的 maven-resources-plugin 版本即可，示例如下：

<plugin>
	<groupId>org.apache.maven.plugins</groupId>
	<artifactId>maven-resources-plugin</artifactId>
	<!--指定恰当版本-->
    <version>3.1.0</version>
</plugin>

就此，已解决。
