开始探索Espresso 2.0,但似乎遇到了打嗝.我无法让测试成功运行任何包含Dagger的项目.当我运行测试时,我得到以下异常(最后的整个堆栈跟踪):

java.lang.NoClassDefFoundError: com/pdt/daggerexample/model/DaggerExampleAppModule$$ModuleAdapter$ProvideMySingletonProvidesAdapter

应用程序在未从AndroidInstrumentationTest运行时运行.

以下是一些相关文件,我还将项目上传到github,以便更快地结账/复制https://github.com/paul-turner/espressoDaggerExample.

的build.gradle:

apply plugin: 'com.android.application'

    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "com.pdt.daggerexample"

        minSdkVersion 16
        targetSdkVersion 21

        versionName "1.0"
    }

        }
        debug {

        }


    }
