这个是当时抛出的异常信息,很奇怪,下面是解决方案(如果有更了解的人欢迎详细解说下,互相学习)

packagingOptions {    exclude 'META-INF/DEPENDENCIES.txt'    exclude 'META-INF/LICENSE.txt'    exclude 'META-INF/NOTICE.txt'    exclude 'META-INF/NOTICE'    exclude 'META-INF/LICENSE'    exclude 'META-INF/DEPENDENCIES'    exclude 'META-INF/notice.txt'    exclude 'META-INF/license.txt'    exclude 'META-INF/dependencies.txt'    exclude 'META-INF/LGPL2.1'  }

这个是完整的解决方案,虽然我不知道这是什么原因,估计是编译器的问题,说不定以后as升级了不会发生,我用的是1.5版本的
