当我更新gradle并构建我的项目时，出现以下错误：
Android resource compilation failed

gradle 2.1.4 没有错误
这里有两个问题
首先，浏览app/src/main/res/values下的文件。其中一个定义一个样式，并使用属性作为该样式的父级：
D：\MyAndroidApp\MyApp2\MyApp\build\intermediates\incremental\mergeWithAnalyticsDebugResources\merged.dir\values\values.xml：2143：错误：样式父级的资源类型"attr"无效。
Style的父母只能是Style。完全删除该父样式或将其更改为其他样式。
其次，属性layout_anchorGravity似乎有两个相互冲突的定义 - 在您的依赖项或本地值文件中。检查此属性的来源，然后覆盖它或完全删除它。
