关于 "Android开发中More than file was fount..."的解决办法

今天在开发过程中出现一个报错，具体内容如下：

More than one file was found with OS independent path 'META-INF/rxjava.properties'

这句话的意思是这个META-INF路径下的rxjava.properties文件被发现多个，也就是说应该是文件重复了，所以要排除多余的文件，通过通过在model中的build.gradle中添加packagingOptions

packagingOptions {
    exclude 'META-INF/DEPENDENCIES'
    exclude 'META-INF/NOTICE'
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/LICENSE.txt'
    exclude 'META-INF/NOTICE.txt'
    exclude 'META-INF/rxjava.properties'
}

根据不同的提示填写不同的exclude。
