运行espresso测试时遇到此错误，完整日志为：

java.lang.NoClassDefFoundError: Failed resolution of: Lorg/junit/runner/notification/RunListener;

我确信build.gradle和库项目build.gradle没有junit冲突，这是我的app / build.gradle

    dependencies {
    compile project(":adr")
    compile fileTree(dir: 'libs', include: ['*.jar'])
//    compile 'junit:junit:4.12'
    compile 'org.hamcrest:hamcrest-core:1.3'
    testCompile 'junit:junit:4.12'
    String ver = "23.4.0"

    compile "com.android.support:design:${ver}"

    compile files("${System.env.HOME}/Dropbox/jvs/ro2/build/libs/ro2.jar")

    androidTestCompile('com.android.support.test:runner:0.5')

    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2')
    compile 'com.github.javafaker:javafaker:0.10'
}

我找到解决方案，我检查上面的日志输出“/data/app/ro.adr.test.test-1/base.apk”，并用apktool反编译，正常情况下，应该包括

base/smali/org/junit/runner/notification/RunListener.smali

但它不是，所以我认为最好的方法是：

rm所有在android项目中构建dirs
rm / data / app / all-project-relative-dir
重新运行调试
上述步骤可以使用脚本

<强>更新

上面的解决方案并不完美，如果你使用gradle，你可以：

gradle --daemon clean uninstallAll

java.lang.NoClassDefFoundError：解析失败：Lorg / junit / runner / notification / RunListener
