gradle中的多风格编译依赖项

Question

有没有办法在Android Studio(build.gradle)中通过多种口味编译依赖项？

我有2个flavorGroups,每2个变种.在4种可能的组合中,我希望能够依赖于lib,只要我是最新的和免费的.latestCompile或freeCompile有效,但latestFreeCompile没有.这是我的build.gradle的相关部分:

android {
    defaultConfig {
        minSdkVersion 7
        targetSdkVersion 19
        versionCode 15
        versionName "1.9." + versionCode
    }

    flavorGroups 'sdk', 'cost'

    productFlavors {
        latest {
            flavorGroup 'sdk'
            minSdkVersion 8
        }
        sdk7 {
            flavorGroup 'sdk'
            minSdkVersion 7
            versionName android.defaultConfig.versionName + ".sdk7"
        }
        free {
            flavorGroup 'cost'
        }
        pro {
            flavorGroup 'cost'
        }
    }
}
dependencies {
    // this works:
    freeCompile files('libs/StartAppInApp-2.2.1.jar')

    // and I would like something like this:
    latestFreeCompile 'com.google.android.gms:play-services:4.1.32' // minSdkVersion:8
}

如果我愿意的话:

latestCompile 'com.google.android.gms:play-services:4.1.32'

那么它也将被包含在latestPro中(不需要),如果我使用:

freeCompile 'com.google.android.gms:play-services:4.1.32'

然后它也将包含在sdk7Free中(虽然它需要SDK 8)

Answer 1

正如官方Android 开发人员网站上所述，如果您想声明产品风格和构建类型的特定组合的依赖项，您需要首先声明该配置。

例如对于free口味和debug类型：

configurations {
    freeDebugImplementation {}
}

dependencies {
    freeDebugImplementation 'com.google.firebase:firebase-ads:9.8.0'
}

进阶：多种风味维度

请注意，如果您的应用程序具有多个风味维度，则必须创建与完整构建变体（所有风味，然后是构建类型）相对应的配置，如下所示：

flavorDimensions "money", "image" 
productFlavors {
    free { dimension "money" }
    paid { dimension "money" }

    picasso { dimension "image" }
    glide { dimension "image" }
}

configurations {
    freePicassoDebugImplementation {}
    freeGlideDebugImplementation {}
}

dependencies {
    freePicassoDebugImplementation 'com.google.firebase:firebase-ads:9.8.0'
    freeGlideDebugImplementation 'com.google.firebase:firebase-ads:9.8.0'
}

Answer 2

我有同样的问题。我用 build.gradle 中的一些 gradle 代码解决了这个问题：

// global variables
ext {
    buildType = ""
    groupCost = ""
    groupSdk = ""
}

def splitCamelCase(String word) {
    def result = []
    int nextStart = 0;
    for (int i = 1; i < word.length(); i++) {
        if(word.charAt(i).isUpperCase()) {
            result.add(word.substring(nextStart, i));
            nextStart = i;
        }
    }

    result.add(word.substring(nextStart));
    return result;
}

// start parameters
println "Start parametes: tasks = " + gradle.startParameter.getTaskNames()

gradle.startParameter.getTaskNames().each { task ->

    // This line is needed to skip other projects' tasks
    // You can safely remove it if you have only one project
    if(!task.startsWith(':<your_application_name>:')) return;

    def taskParts = splitCamelCase(task.split(":").last());
    def groupCostPrefix = taskParts[taskParts.size() - 3];
    def groupSdkPrefix = taskParts[taskParts.size() - 2];
    def buildTypePrefix = taskParts[taskParts.size() - 1];

    if("Debug".startsWith(buildTypePrefix)) {
        buildType = 'debug';
    }
    else if("Release".startsWith(buildTypePrefix)) {
        buildType = 'release';
    }
    else {
        return; // do not process tasks that are not ending with proper build type.
    }

    if("Free".startsWith(groupCostPrefix)) {
        groupCost = 'free';
    }
    else if("Pro".startsWith(groupCostPrefix)) {
        groupCost = 'pro';
    }

    if("Sdk7".startsWith(groupSdkPrefix)) {
        groupSdk = 'froyo';
    }
    else if("Latest".startsWith(groupSdkPrefix)) {
        groupSdk = 'latest';
    }
}

然后您所需要做的就是在“依赖项”部分中添加以下代码：

if(groupSdk == 'latest' && groupCost == 'free') {
    compile 'com.google.android.gms:play-services:4.1.32'
}
