Android的测试：“多DEX文件”使用'支票的gradle connectedCheck“时 [英] Android testing: 'Multiple dex files' when using 'gradle check connectedCheck'

问题描述

当我运行Android基于仿真的测试，

When I run android emulator-based tests with:

gradlew check connectedCheck

...它失败：

... it fails with:

 com.android.dx.util.DexException: Multiple dex files define Lorg/hamcrest/Description;

下面是我的build.gradle文件：

Here's my build.gradle file:

buildscript {
    repositories {
        mavenCentral()
        maven {
            url 'https://oss.sonatype.org/content/repositories/snapshots/'
        }
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:0.7.0'
        classpath 'com.squareup.gradle:gradle-android-test-plugin:0.9.1-SNAPSHOT'
    }
}

apply plugin: 'android'
apply plugin: 'android-test'

repositories {
    mavenCentral()
    maven {
        url 'https://oss.sonatype.org/content/repositories/snapshots/'
    }
}

task wrapper(type: org.gradle.api.tasks.wrapper.Wrapper) {
    gradleVersion = '1.9'
}

android {
    compileSdkVersion 17
    buildToolsVersion "18.1"

    defaultConfig {
        minSdkVersion 13
        targetSdkVersion 18
    }

    sourceSets {
        instrumentTest.setRoot('src/test')
    }

    lintOptions {
        abortOnError false
    }
}

dependencies {
    compile 'com.android.support:support-v4:13.0.+'
    compile fileTree(dir: 'libs', include: '*.jar')

    testCompile 'junit:junit:4.10'
    testCompile 'org.robolectric:robolectric:2.3-SNAPSHOT'
    testCompile 'com.squareup:fest-android:1.0.+'
    instrumentTestCompile 'junit:junit:4.10'
    instrumentTestCompile 'org.robolectric:robolectric:2.3-SNAPSHOT'
    instrumentTestCompile 'com.squareup:fest-android:1.0.+'
}

我使用Android的工作室，但测试都是在命令行中运行。

I am using Android Studio, but the tests are run from command line.

运行带有roboelectric非基于模拟器测试（ gradlew测试）的罚款。

Running non-emulator based tests with roboelectric (gradlew test) works fine.

我相信这是包括两次jar文件，但不知道哪一个，以及如何解决。
建议？

I believe it is a jar file that is included twice, but don't know which one and how to fix. Suggestions?

修改

这似乎是在 instrumentTestCompile'的JUnit：JUnit的：4.10行导致该问题。但是，当我取了这一点，该roboelectric测试不编译。我应该如何配置，这样我可以同时运行仿真器和基于roboeletric为基础的测试？

It seems that it is the instrumentTestCompile 'junit:junit:4.10' line that is causing the problem. But when I take that out, the roboelectric test doesn't compile. How should I configure this so that I can run both emulator-based and roboeletric-based tests?

推荐答案

这是因为JUnit的4.10包括一些Hamcrest类（淘气）。它的固定在4.11因此只需升级。

This is because JUnit 4.10 includes some Hamcrest classes (naughty). It's fixed in 4.11 so just upgrade.
