摇篮打造为集的Andr​​oid项目（包括库） [英] Gradle build for set of Android projects (including libraries)

问题描述

我有2 5款Android模块（安卓库项目）的Andr​​oid应用程序。共有7 Eclipse项目。我想启用摇篮打造他们。我加了 build.gradle 在根文件夹，并列入 settings.gradle

I have 2 Android apps with 5 Android modules (Android library project). Total 7 Eclipse projects. I want to enable Gradle build for them. I added build.gradle in the root folder and listed all project in settings.gradle

include ':app1'
include ':app2'
...

不过，我发现，我需要复制粘贴以下部分的每一个7项目

However I discovered that I need to copy-paste section below in every one of 7 project

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.3"

    defaultConfig {
        minSdkVersion 1
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
    }
        ... // and so on like source folders configuration
}

原因：当我添加应用插件：'机器人'里面的根 build.gradle （见<一href="http://stackoverflow.com/questions/23864068/could-not-find-method-android-in-root-of-multimodule-project">Could没有找到的多模块项目根法的Andr​​oid（）），
那么我不能应用插件：机器人库图书馆项目（见<一href="http://stackoverflow.com/questions/23864292/minimal-gradle-configuration-for-android-library-in-multimodule-project">Minimal摇篮配置的多模块项目的Andr​​oid库）

Reason: when I add apply plugin: 'android' inside root build.gradle (see Could not find method android() in root of multimodule project),
then I can't apply plugin: 'android-library' for libraries projects (see Minimal Gradle configuration for Android library in multimodule project)

但它是什么，我想避免，具有不同版本的Andr​​oid，并在不同的地方指定的Andr​​oid工具。

But it is what I want to avoid, having different version of Android and Android tools specified in different places.

如何运行如下此配置中获得尽可能多的东西尽可能在一个 build.gradle 配置文件。

How can I minify this configuration to have as many things as possible in one build.gradle config file.

推荐答案

您可以使用根你的 build.gradle ，也可以在<$ C定义一些值$ C> gradle.properties 的根文件夹来实现自己的范围。

You can use your build.gradle in root, or you can define some values in gradle.properties in root folder to achieve your scope.

例如：

根/ build.gradle ：

ext {
    compileSdkVersion = 19
    buildToolsVersion = "19.0.3"
}

模块/ build.gradle ：

android {
    compileSdkVersion rootProject.ext.compileSdkVersion
    buildToolsVersion rootProject.ext.buildToolsVersion
}

或使用性质

根/ gradle.properties ：

VERSION_NAME=1.0.1
VERSION_CODE=11

模块/ build.gradle ：

android {

    defaultConfig {
        versionName project.VERSION_NAME
        versionCode Integer.parseInt(project.VERSION_CODE)

    }
