Android Studio Error:warning: Ignoring InnerClasses attribute for an anonymous inner class

最近在下载打开某些项目直接运行时遇见了几次这样的错误，一直build不过去，错误如下：

Error:warning: Ignoring InnerClasses attribute for an anonymous inner class
Error:associated EnclosingMethod attribute. This class was probably produced by a
Error:(com.baidu.lbsapi.auth.d) that doesn't come with an

其实在点击运行的时候AS有提示，当时没注意直接点击的运行，

上面在点击了运行之后已经给出了提示当前的版本pro-release没有签名让选择一个签名的运行。我当时没注意直接点击了run

之后我点击了继续，然后它又提示了一次，我直接又yes了，最后当然是编译没有通过。

好了上面都是我的错误操作经验，下面说下遇见这种情况怎么解决

第一次运行时，点击build ——》select build variant

如果已经运行过了，在侧边栏寻找，在BuildVariant 的proRelease处点击选择其他版本进行运行，proRelease是根据你项目设置进行显示的并不固定。
