尝试 dataBinding 时，遇到下面错误：

Generated class list does not exist {module root}\build\intermediates\data-binding-info\release\_generated.txt

具体报错：

java.lang.RuntimeException: failure, see logs for details. Generated class list does not exist C:\git\android-lm\androidCore\build\intermediates\data-binding-info\debug\\_generated .txt

解决方案：

在build.gradle文件中配置

android {
    ...
    dataBinding {
        enabled = true
    }
   ...
}

注意

如下图：

两个Module都需要配置

如果有多个Module的话，最好所有Module 的 build.gradle 文件中都配置上，
我就是只配置了build.gradle(Moudle:library)，而没有配置 build.gradle(Moudle:app)，才导致的报错。
