android build获取ext,如何获取Android project下 build.gradle、gradle.properties、local.properties文件中定义的属性或变量...

1、读取project下 build.gradle

属性：

ext {

compileSdk = 28

minSdk = 17

targetSdk = 28

support = "28.0.0"

buildTools = "28.0.0"

supportLibraryVersion = "28.0.0"

versionCode = 4

versionName = "1.0.4"

cfgs = [

utilcodeVersion: "1.23.0",

eventbusVersion: "3.0.0",

glideVersion: "3.7.0",

retrofitVersion: "2.4.0",

rxandroidVersion: "1.1.0",

rxjavaVersion: "1.1.0",

okhttpVersion: "3.5.0",

loggingInterceptorVersion: "3.0.0",

autosizeVersion: "1.1.2",

baseRecyclerViewAdapterHelperVersion: "2.9.30",

lottieVersion: "2.1.0",

fastjsonVersion: "1.2.47",

qmuiVersion: "1.1.3",

bottomNavigationBarVersion: "2.1.0",

recyclerViewVersion: "28.0.0",

zhihuMatisse:"0.5.2-beta2"

]

}

读取：

defaultConfig {

applicationId "com.star.commodity.release"

minSdkVersion rootProject.ext.minSdk

targetSdkVersion rootProject.ext.targetSdk

versionCode rootProject.ext.versionCode

versionName rootProject.ext.versionName

multiDexEnabled true

}

implementation "com.android.support:appcompat-v7:${supportLibraryVersion}"

implementation "com.blankj:utilcode:${cfgs.utilcodeVersion}"

2、读取gradle.properties

属性：

isModule=false

读取：

在Module 的build.gradle 中

isModule.toBoolean() 或者 直接取isModule就可以了

3、读取local.properties

Properties properties = new Properties()

properties.load(project.rootProject.file('local.properties').newDataInputStream())

def sdkDir = properties.getProperty('sdk.dir')

def ndkDir = properties.getProperty('ndk.dir')

举例：同一套分支，多个项目同时使用，动态设置版本号等信息

第一步：在gradle.properties中添加属性

CUR_PROJECT=UGA

第二步：在App下的build.gradle中写一个动态获取的方法

def getCurProjectVersionName(){

if (CUR_PROJECT.equals("UGA")) {

return "2.0.5"

} else {

return "2.3.1"

}

}

def getCurProjectVersionCode() {

if (CUR_PROJECT.equals("UGA")) {

return 2000005

} else {

return 2003001

}

}

第三步：调用方法获取版本信息

defaultConfig {

versionCode getCurProjectVersionCode()

versionName getCurProjectVersionName()

signingConfig signingConfigs.config

multiDexEnabled true

}
