在mcl登陆账号成功后立即报错：
W/stderr: SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
W/stderr: SLF4J: Defaulting to no-operation (NOP) logger implementation
W/stderr: SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
W/stderr: ERROR StatusLogger Log4j2 could not find a logging implementation. Please add log4j-core to the classpath. Using SimpleLogger to log to the console...]
官网给出的解决办法（大概）：This warning message is reported when the class could not be loaded into memory. This happens when no appropriate SLF4J binding ould be found on the class path. Placing one (and only one) of slf4j-nop.jar slf4j-simple.jar, slf4j-log4j12.jar, slf4j-jdk14.jar or logback-classic.jar on the class path should solve the problem.
意思是你把这几个jar其中之一添加到classpath应该就没问题了。（或者说根据上面的错误提示之还要进行一些操作？）
但是百度了许多“如何将jar添加到classpath”的方法，发现貌似没有一个可以让我成功规避这个错误（也可能是我不会操作哈哈）。
在这里求助一下解决方案，thanks for help >w<
