Android Gradle Unit测试来自JAR的迁移 - 来自junit和mockito的复制hamcrest文件

Question

我最终将使用JAR文件运行的旧单元测试迁移到使用gradle但是我在获取正确的组合时遇到了很多麻烦,并且不确定我在做什么是对还是错.首先,这些是我正在使用的所有jar文件.

dexmaker-1.0.jar
dexmaker-mockito-1.0.jar
fest-android-1.0.7.jar
fest-assert-core-2.0M10.jar
fest-util-1.2.5.jar
junit-4.11.jar
mockito-all-1.9.5.jar
the-missing-android-xml-junit-test-runner-release-1.3_2.jar  <---- I think this is used to get reports for the unit tests, is there a way that I don't have to use this anymore?

当我将所有这些JAR导入时,就像下面的JAR一样,它运行正常,所以这是一件好事,但并不理想:

androidTestCompile fileTree(dir: 'libs/test', include: '*.jar')

接下来,我尝试将所有JAR文件更改为gradle-maven依赖项,如下所示

androidTestCompile fileTree(dir: 'libs/test', include: '*.jar')
androidTestCompile 'junit:junit:4.11+'
androidTestCompile ('com.squareup:fest-android:1.0.+') {
    exclude group: 'com.android.support'
}
androidTestCompile 'org.easytesting:fest-assert-core:2.0M10'
androidTestCompile 'org.easytesting:fest-util:1.2.+'
androidTestCompile 'org.mockito:mockito-all:1.9.+'
androidTestCompile 'com.google.dexmaker:dexmaker:1.+'
androidTestCompile 'com.google.dexmaker:dexmaker-mockito:1.+'

这不起作用,因为在尝试构建和运行单元测试时,我得到以下结果:

UNEXPECTED TOP-LEVEL EXCEPTION:
com.android.dex.DexException: Multiple dex files define Lorg/hamcrest/Description;
    at com.android.dx.merge.DexMerger.readSortableTypes(DexMerger.java:594)
    at com.android.dx.merge.DexMerger.getSortedTypes(DexMerger.java:552)
    ... 

所以我看了几个地方来帮我解决这个问题,Android Gradle DexException:多个dex文件定义Lorg/hamcrest /描述 Android测试:'多个dex文件'使用'gradle check connectedCheck'Android + Powermock + Mockito + Maven build ClassNotFoundException出错,他们建议我尝试以下方法:

androidTestCompile fileTree(dir: 'libs/test', include: '*.jar')
androidTestCompile('junit:junit:4.11+') {
    exclude group: 'org.hamcrest'
}
androidTestCompile ('com.squareup:fest-android:1.0.+') {
    exclude group: 'com.android.support'
}
androidTestCompile 'org.easytesting:fest-assert-core:2.0M10'
androidTestCompile 'org.easytesting:fest-util:1.2.+'
androidTestCompile 'org.mockito:mockito-all:1.9.+'
androidTestCompile 'com.google.dexmaker:dexmaker:1.+'
androidTestCompile 'com.google.dexmaker:dexmaker-mockito:1.+'

和

androidTestCompile fileTree(dir: 'libs/test', include: '*.jar')
androidTestCompile 'junit:junit:4.11+'
androidTestCompile ('com.squareup:fest-android:1.0.+') {
    exclude group: 'com.android.support'
}
androidTestCompile 'org.easytesting:fest-assert-core:2.0M10'
androidTestCompile 'org.easytesting:fest-util:1.2.+'
androidTestCompile('org.mockito:mockito-all:1.9.5') {
    exclude group: 'org.hamcrest'
}
androidTestCompile 'com.google.dexmaker:dexmaker:1.+'
androidTestCompile 'com.google.dexmaker:dexmaker-mockito:1.+'

但仍然产生以下结果:

UNEXPECTED TOP-LEVEL EXCEPTION:
com.android.dex.DexException: Multiple dex files define Lorg/hamcrest/Description;
    at com.android.dx.merge.DexMerger.readSortableTypes(DexMerger.java:594)
    at com.android.dx.merge.DexMerger.getSortedTypes(DexMerger.java:552)

我根据一些建议尝试了以下更改junit和mockito.

androidTestCompile 'junit:junit-dep:4.11+'
androidTestCompile 'org.mockito:mockito-core:1.9.+'

我得到了

You can ignore those files in your build.gradle:
android {
  packagingOptions {
    exclude 'LICENSE.txt'
  }
}

有什么建议或帮助吗？我不想再回到使用JAR了.

实际上,我最后只是通过添加就知道了它并且它起作用了.

android {
    // stuff before

    packagingOptions {
        exclude 'META-INF/LICENSE.txt'
        exclude 'LICENSE.txt'
    }
}

我的依赖项有以下几点

dependencies {
    androidTestCompile ('com.squareup:fest-android:1.0.+') {
        exclude group: 'com.android.support'
    }
    androidTestCompile 'com.google.dexmaker:dexmaker:1.+'
    androidTestCompile 'com.google.dexmaker:dexmaker-mockito:1.+'

    androidTestCompile 'junit:junit:4.11'
    androidTestCompile 'org.hamcrest:hamcrest-library:1.3'
    androidTestCompile 'org.mockito:mockito-core:1.9.5'
}
