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

Question

我在运行 espresso 测试时遇到这个错误，完整的日志是:

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

我确定在 build.gradle 和库项目 build.gradle 中没有 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'
}

我找到了解决方案，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，在正常情况下, 它应该包括

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

但它没有，所以我认为最好的方法是:

• rm android 项目中的所有构建目录
• rm/data/app/all-project-relative-dir
• 重新运行调试
• 以上步骤可以用脚本完成

更新

以上方案并不完美，如果你使用gradle，你可以:

gradle --daemon clean uninstallAll
