gradle - Espresso + RoboBinding + Dagger:带有gradle的依赖项管理

Question

在Android Studio中运行Espresso工具测试时，我遇到了很多困难。

我认为这与我的 build.gradle 有关:

apply plugin: 'com.android.application'
apply plugin: 'com.neenbedankt.android-apt'
apply plugin: 'android'
apply plugin: 'robolectric'

android {
    compileSdkVersion 21
    buildToolsVersion "20.0.0"

    defaultConfig {
        applicationId "com.example.myapp"
        minSdkVersion 18
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "com.google.android.apps.common.testing.testrunner.GoogleInstrumentationTestRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    sourceSets {
        androidTest {
            setRoot('src/test')
        }
    }
    packagingOptions {
        exclude 'META-INF/LICENSE.txt'
        exclude 'LICENSE.txt'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/NOTICE'
    }
    dexOptions {
        jumboMode true
    }
}

    }

     androidTestCompile('com.jakewharton.espresso:espresso:1.1-r3') {

         exclude group: 'javax.inject'
         exclude group: 'com.google.guava', module: 'guava'
    }

    androidTestCompile("junit:junit:${junitVersion}") {
        exclude module: 'hamcrest-core'
    }

    androidTestCompile("org.robobinding:robobinding:${robobindingVersion}") {

    }

    androidTestCompile 'com.squareup:fest-android:1.0.+'

    apt "org.robobinding:codegen:$robobindingVersion"
    compile("org.robobinding:robobinding:$robobindingVersion:with-dependencies") {
        exclude group: 'com.google.guava', module: 'guava'
    }
    apt "org.androidannotations:androidannotations:${androidAnnotationsVersion}"

apply plugin: 'idea'

}


android.applicationVariants.all { variant ->
    def aptOutput = file("${project.buildDir}/generated/source/apt/${variant.dirName}")
    println "****************************"
    println "variant: ${variant.name}"
    println "manifest:  ${variant.outputs[0].processResources.manifestFile}"
    println "aptOutput:  ${aptOutput}"
    println "****************************"

    variant.javaCompile.doFirst {
        println "*** compile doFirst ${variant.name}"
        aptOutput.mkdirs()
        variant.javaCompile.options.compilerArgs += [
                '-processorpath', configurations.apt.getAsPath(),
                '-AandroidManifestFile=' + variant.outputs[0].processResources.manifestFile,
                '-s', aptOutput
        ]
    }
}

当我使用此版本的build.gradle来运行测试时，出现以下错误:

5508-5508/com.example.myapp E/AndroidRuntime﹕ FATAL EXCEPTION: main
    java.lang.IllegalAccessError: Class ref in pre-verified class resolved to unexpected implementation

当我删除androidTestCompile“javax.inject:javax.inject:$ {javaxinjectVersion}”时，出现另一个错误:

如果有人可以给我一个提示，请先谢谢。

使用Espresso 2.0时，如果需要junit，则需要更改依赖项以使用junit-dep。

androidTestCompile 'junit:junit-dep:4.11'
