Gradle 中的 Android Module 特定库



我有一个安卓模块，核心，我在几个项目中使用它。核心模块具有单元测试（应该如此）。核心模块还依赖于一些外部 jar。模块本身构建良好，我得到了一个漂亮的闪亮 AAR，但我无法构建测试。Gradle（实际上是dex）抱怨某些库被多次包含。测试使用自定义测试运行程序，这是它们唯一的 jar 依赖项。

我的目录层次结构是

├── core
│   ├── libs
│   └── src
│       ├── instrumentTest
│       │   ├── assets
│       │   ├── java
│       │   └── res
│       └── main
│           ├── java
│           └── res
└── gradle
    └── wrapper

我的build.gradle是

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.6.+'
    }
}
apply plugin: 'android-library'
repositories {
    mavenCentral()
}
android {
    compileSdkVersion 18
    buildToolsVersion "18.1.0"
    defaultConfig {
        minSdkVersion 8
        targetSdkVersion 18
    }
}
dependencies {
    compile 'org.projectlombok:lombok:1.12.2'
    compile fileTree(dir: 'libs', include: '*.jar')
}

我相信我的解决方案是拥有以下目录层次结构：

├── core
│   └── src
│       ├── instrumentTest
│       │   ├── assets
│       │   ├── java
│       │   ├── libs
│       │   └── res
│       └── main
│           ├── java
│           ├── libs
│           └── res
└── gradle
    └── wrapper

并将 jar 分别包含在main和instrumentTest模块中。但我不确定我必须在我的build.gradle文件中做什么。我尝试在android块中添加一个sourceSets块，里面有main和instrumentTest块，每个块都有自己的dependencies部分：

sourceSets {
    main {
        dependencies {
            compile fileTree(dir: 'main/libs', include: '*.jar')
        }
    }
    instrumentTest {
        dependencies {
            compile fileTree(dir: 'instrumentTest/libs', include: '*.jar')
        }
    }
}

但是 Gradle 似乎根本没有接受它（很多未解决的名字）。

compileTest目标工作正常并成功完成，但connectedInstrumentTest产生以下错误：

我能在这里做些什么来消除这些错误？

这种特定情况下的问题是libs文件夹中已经有一个lombok.jar，它与声明的依赖项冲突。我最终删除了 jar 并选择使用下载的版本。

今天让我震惊的另一个例子是因为 android 插件在多个 jar 文件中找到了相同的文件。例如，我对Apache公共库有一些依赖。这些文件共享相同的许可证、通知文件等。安卓插件抛出了类似的错误。

从 Android 插件 0.7.1 开始，您可以手动排除这些文件：

packagingOptions {
    exclude 'META-INF/NOTICE.txt'
    exclude 'META-INF/LICENSE.txt'
    exclude 'META-INF/services/javax.annotation.processing.Processor'
}

当您面临双重包含的包裹时，您可以尝试以下方法：

compile ('org.roboguice:roboguice:2.0') {
    exclude module: 'guice'
}

在这种情况下，RoboGuice 会尝试打包 Guice，因此如果您已经添加了它，则会遇到此问题。不知何故，我认为当您调用connectedInstrumentTest时，打包并不完全像您调用组装或组装发布时那样完成

。
