Gradle + Robolectric + Espresso:不能单独运行

Question

我试图修改以下模板：德卡德级

我使用Android 0.8.14 (beta)。

这是我的build.gradle

apply plugin: 'com.android.application'
apply plugin: 'com.neenbedankt.android-apt'
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 {
            runProguard 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'
    }
}

robolectric {
    include '**/*Test.class'
    exclude '**/espresso/**/*.class'
}

configurations {
    apt
}

apt {
    arguments {
        resourcePackageName android.defaultConfig.packageName
        androidManifestFile variant.outputs[0].processResources.manifestFile
    }
}

ext {

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

    androidTestCompile("org.robolectric:robolectric:${robolectricVersion}") {
        exclude module: 'classworlds'
        exclude module: 'commons-logging'
        exclude module: 'httpclient'
        exclude module: 'maven-artifact'
        exclude module: 'maven-artifact-manager'

    }

    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:${androidAnnotationsVersion}"
    compile "org.androidannotations:androidannotations-api:${androidAnnotationsVersion}"
    apt "com.squareup.dagger:dagger-compiler:${daggerVersion}"
    compile "com.squareup.dagger:dagger:${daggerVersion}"

    compile group: 'commons-io', name: 'commons-io', version: "${commonsioVersion}"

}

apply plugin: 'idea'
idea {
    module {
        testOutputDir = file('build/test-classes/debug')
    }
}

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

我尝试了运行单元测试的方法：

当我使用gradlew测试时，我会得到异常，因为所有测试(也是检测)都会执行。

当我使用Android 运行JUnit测试时，会得到以下错误：

出于各种原因，我放弃了上述方法，转而将我的Robolectric测试保留在一个Gradle子模块中。您可以找到我写过的一篇关于我为什么向这个方向移动的博客文章，以及一个deckard项目的分叉，它向您展示了这里是如何实现的。
