android - 如何设置与 AndroidJunitRunner 的依赖关系？

Question

我使用 gradle 构建我的 android 应用程序。

我按照文档 ( https://developer.android.com/topic/libraries/testing-support-library/index.html ) 来定义依赖项。

但是，gradle build 总是说找不到一些依赖。

Here is the gradle script

    apply plugin: 'com.android.application'
    buildscript {
        repositories {
            mavenCentral()
        }

        dependencies {
            classpath 'com.android.tools.build:gradle:1.1.0'
        }
    }
    android {

        defaultConfig {
            testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        }

        compileSdkVersion "android-22"
        buildToolsVersion "20.0.0"

        sourceSets {
            main {
                manifest.srcFile 'AndroidManifest.xml'

            }
            androidTest.setRoot('tests')
           }

        dependencies {
            androidTestCompile 'junit:junit:4.12'
            androidTestCompile 'com.android.support.test:runner:0.4.1'
        // Set this dependency to use JUnit 4 rules
            androidTestCompile 'com.android.support.test:rules:0.4'
        // Set this dependency to build and run Espresso tests
            androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.1'
        // Set this dependency to build and run UI Automator tests
            androidTestCompile 'com.android.support.test.uiautomator:uiautomator-v18:2.1.2'
        }
    }

即使我在 androidTestCompile 中指定了 junit 4.12，它仍然通过 $android_sdk_home 搜索库，但不是预期的 maven central。

谢谢!

更新:我认为问题是您需要在 buildscript 部分之外的另一个 repositories{mavenCentral()} 部分。我总是为此使用根脚本，但我不确定。你所有的脚本看起来都很奇怪，请阅读 this :

buildscript { ... } configures the code driving the build. In this case, this declares that it uses the Maven Central repository, and that there is a classpath dependency on a Maven artifact. This artifact is the library that contains the Android plugin for Gradle in version 0.11.1 Note: This only affects the code running the build, not the project. The project itself needs to declare its own repositories and dependencies. This will be covered later.

之前的回复:其他可能的问题:

替换

compileSdkVersion "android-22"

通过

compileSdkVersion 22

并且需要安装使用更高版本的build tools 22.0.1+

Note: Always use a build tools version whose major revision number is higher or equal to that of your compilation target and target SDK.

并将依赖项 block 移动到 android block 之外，如 here .

The dependencies element is outside and after the android element.

我不知道确切的问题抱歉，请尝试 working sample首先，或者等待更好的响应。
