Maven打包项目错误：Failed to execute goal org.apache.maven.plugins:maven-resources-plugin:3.2.0:resources

在执行mvn clean package时报错：

1.在pom文件中加入一下这段代码，问题解决

<build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-resources-plugin</artifactId>
                <version>2.7</version>
            </plugin>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

2.重新执行mvn clean package已经没有报错了
