官方解决方案：

忽略clean错误,设置failOnError为false

<build>
  [...]
    <plugin>
      <artifactId>maven-clean-plugin</artifactId>
      <version>3.0.0</version>
      <configuration>
        <failOnError>false</failOnError>
      </configuration>
    </plugin>
  [...]
</build>

或者添加代码：

mvn clean -Dmaven.clean.failOnError=false

这里选用的第二种方法，编译通过：
