我想在 gradle 中使用 espresso 测试。为此，我尝试使用 double-espresso由 Jake Wharton 编写，但它不起作用。
我读到它可能是重复的依赖项，但我已经排除了 Dagger 和 Support-v4 库，就像 Jake 在他的 README 中写的那样。
任何人都可以就这里可能出现的问题给我建议吗？

最佳答案
由于在 org.hamcrest.integration 包中找不到类，请尝试排除它。然后你的依赖项看起来像
// Espresso
androidTestCompile ('com.jakewharton.espresso:espresso:1.1-r2') {
exclude group: 'com.squareup.dagger', module: 'dagger'
exclude group: 'org.hamcrest', module: 'hamcrest-integration'
}
androidTestCompile ('com.jakewharton.espresso:espresso-support-v4:1.1-r2') {
exclude group: 'com.android.support', module: 'support-v4'
// Not sure whether line below is needed
exclude group: 'org.hamcrest', module: 'hamcrest-integration'
}
关于android - 由于 'java.lang.IllegalAccessError'，检测运行失败。 Gradle + Espresso ，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/22486481/
