Unable to execute dex: Multiple dex files define Lorg/slf4j/ILoggerFactory的解决方法

参考：http://blog.csdn.net/mxlxiao7/article/details/8978930

最近在android项目下引入mina框架包，但在Run As Android Application时提示错误：

Unable to execute dex: Multiple dex files define Lorg/slf4j/ILoggerFactory;

Unable to execute dex: Multiple dex files define Lorg/slf4j/ILoggerFactory;

参考上面链接地址的方法，怎样都无法删除libs下的jar包，然后我试着右键 Android Private Libraries -->Build Path --> Remove from Build Path

再重新运行一次，成功了。猜测这是因为Android Private Libraries 和Referenced Libraries下的jar包重复了
