使用maven打包项目时报错：[INFO] Using 'UTF-8' encoding to copy filtered resources.

有时候maven打包项目时会报这样的错：

项目一直启动不了，很耽误时间。

 

解决方法：

===在springboot项目pom文件里的<build>标签里加上''maven-resources-plugin''插件，或者修改该插件的版本：===

<build>
 <plugins>
 <plugin>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-maven-plugin</artifactId>
 </plugin>
 <plugin>
 <groupId>org.apache.maven.plugins</groupId>
 <artifactId>maven-resources-plugin</artifactId>
 <version>2.6</version>
 </plugin>
 </plugins>
</build>

此时我使用的是2.6版本，只要不报错都可以，然后去Maven选项栏clean install一下，就能正常运行了。
