AndroidStudio统一管理gradle脚本

Android

目的

当工程集成很多Modules时，每个Module都有一个build.gradle，并且带有如下重复的代码；对每个build.gradle修改很麻烦，因此统一管理build.gradle文件是必要的

// 重复代码
android {
    compileSdkVersion 25
    buildToolsVersion "25.0.0"

    defaultConfig {
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:24.2.1'
}

优化代码
使用相同的编译配置
统一管理远程依赖
减少sync project次数

本地配置

在项目根目录下创建config.gradle文件，作为管理配置文件

import java.util.regex.Matcher
import java.util.regex.Pattern

config.gradle

在项目根目录的build.gradle中引用，供其他的Module使用

注意：
1. 如果想使用ext的值，则只能在项目根目录的build.gradle中引用
2. 想让单独的Module使用，则在该Module的build.gradle里引入，但是此时不能使用ext的值，否则会提示无法找到”Error:Cannot get property ‘xxx’ on extra properties extension as it does not exist”
