Gradle构建文件

将以下内容添加到Android项目build.gradle的末尾：

task copyJarDependencies(type: Copy) {
    description = 'Used for Eclipse. Copies all dependencies to the libs directory. If there are any AAR files it will extract the classes.jar and rename it the same as the AAR file but with a .jar on the end.'
    libDir = new File(project.projectDir,'/libs')
    println libDir
    println 'Adding dependencies from compile configuration'
    configurations.compile.filter {it.name.endsWith 'jar'}.each { File file -> moveJarIntoLibs(file)}
    println 'Adding dependencies from releaseCompile configuration'
    configurations.releaseCompile.filter {it.name.endsWith 'jar'}.each { File file -> moveJarIntoLibs(file)}
    println 'Adding dependencies from debugCompile configuration'
    configurations.debugCompile.filter {it.name.endsWith 'jar'}.each { File file -> moveJarIntoLibs(file)}
    println 'Adding dependencies from instrumentTestCompile configuration'
    configurations.instrumentTestCompile.filter {it.name.endsWith 'jar'}.each { File file -> moveJarIntoLibs(file)}
    println 'Extracting dependencies from compile configuration'
    configurations.compile.filter {it.name.endsWith 'aar'}.each { File file -> moveAndRenameAar(file) }
    println 'Extracting dependencies from releaseCompile configuration'
    configurations.releaseCompile.filter {it.name.endsWith 'aar'}.each { File file -> moveAndRenameAar(file) }
    println 'Extracting dependencies from debugCompile configuration'
    configurations.debugCompile.filter {it.name.endsWith 'aar'}.each { File file -> moveAndRenameAar(file) }
    println 'Extracting AAR dependencies from instrumentTestCompile configuration'
    configurations.instrumentTestCompile.filter {it.name.endsWith 'aar'}.each { File file -> moveAndRenameAar(file) }
}

void moveJarIntoLibs(File file){
    println 'Added jar ' + file
        copy{
            from file
            into 'libs'
        }
}

void moveAndRenameAar(File file){
    println 'Added aar ' + file
    def baseFilename = file.name.lastIndexOf('.').with {it != -1 ? file.name[0..<it] : file.name}

    // directory excluding the classes.jar
    copy{
        from zipTree(file)
        exclude 'classes.jar'
        into 'libs/'+baseFilename
    }

    // Copies the classes.jar into the libs directory of the expoded AAR.
    // In Eclipse you can then import this exploded ar as an Android project
    // and then reference not only the classes but also the android resources :D 
    copy{
        from zipTree(file)
        include 'classes.jar'
        into 'libs/' + baseFilename +'/libs'
        rename { String fileName ->
            fileName.replace('classes.jar',baseFilename + '.jar')
        }
    }
}

建筑与Gradle

跑 ：

“毕业干净”

您应该在libs目录中找到所有的依赖项和分解的AAR.这就是Eclipse应该需要的.

在Eclipse中导入

现在这是真正的利益开始的地方.从上面的渐变步骤生成libs目录后,您会注意到那里还有文件夹.这些新文件夹是您的build.gradle文件中的AAR依赖关系.

现在很酷的部分是当您将现有的Android项目导入到Eclipse中时,它也会将爆炸的AAR文件夹检测为可以导入的项目！

1.在项目的libs目录下导入这些文件夹,不要导入任何’build’文件夹,它们是由Gradle生成的

2.确保执行项目 – >清理您添加的所有AAR项目.在您的工作区中,检查每个AAR爆炸项目在project.properties中具有以下内容：

target=android-<YOUR INSTALLED SKD VERSION GOES HERE>
android.library=true

3.现在在您的主要Android项目中,您可以使用ADT添加库引用,也可以编辑project.properties文件并添加

android.libraries.reference.1 =库/ someExplodedAAR /

4.现在您可以右键单击您的主要Android项目并运行为 – > Android应用程序

但这甚至是什么意思？

>这意味着您不需要任何Android AAR Gradle依赖项的源代码,以便在Eclipse中引用它的类和资源.>上面的gradle构建脚本使用AAR文件并准备在Eclipse中使用.一旦你把它添加到你的工作区,你就可以专注于实际的主要的Android项目.>您现在可以使用Eclipse进行调试和开发,并使用ADT进行部署,并将AAR依赖关系正确地捆绑在APK中.当你需要做一些特定的构建,那么你可以使用渐变.
