根据buildType更改android项目中的.properties文件和settings.gradle文件

问题描述

我有一个android gradle项目，我有两个buildTypes：QA和prod。我想根据构建类型更改.properties文件中的属性。我也想根据buildType更改settings.gradle文件中的一个值。我是新来的android和gradle，所以如果这是一个非常基本的问题，请原谅我。

这是我的.properties文件：

  build_number = 3.1-SNAPSHOT 
 version_number = 3.1.0 
 environment_name = prod //需要在qa环境中更改为environment_name = qa 
  

这是我的settings.gradle文件：

  rootProject.name ='tom-android-prod'//这需要在qa环境中更改为rootProject.name ='tom-android-qa'
  
 
 $ b 
这是我的build.gradle文件： 
 
 
  apply plugin：'com.android.application'
 
 buildscript {
 repositories {
 jcenter（）
 
} 
 
依赖关系{
 
 classpath'com.android.tools.build:gradle:1.3.1'
 
} 
} 
 
 
 android {
 compileSdkVersion 21 
 buildToolsVersion21.1.0
 
 defaultConfig {
 multiDexEnabled true 
 
 $ b dexOptions {
 javaMaxHeapSize4g
} 
 
 packagingOptions {
 exclude'META-INF /相关的
排除'META-INF / LICENSE'
排除'META-INF / LICENSE.txt'
排除'META-INF / license.txt'
排除'META- INF / NOTICE'
排除'META-INF / NOTICE.txt'
排除'META-INF / notice.txt'
排除'META-INF / ASL2.0'
 } 
 $ b配置{
全部* .exclude组：'com.android.support'，模块：'support-v4'
} 
 
} 
 
依赖性{
 .... 
} 
  
 
 
解决方案
我并不确定你的目标是以 environment_name 作为未使用的目标，但想象你需要设置一个变量只适用于特定版本，那么你可以这样做： {
 environment_name = null 
} 
 android {
 //其他东西... 
 buildTypes {
 qa {
 project.ext。 environment_name =qa
} 
 prod {
 project.ext.environment_name =prod
} 
} 
} 
 
 //稍后您可以使用像这样的变量
 printlnHello variable：$ project.ext.environment_name
  

使用buildTypes应该不需要修改 rootProject.name ='tom-android'。或者你可以用相同的方式使用 productFlavors 闭包......取决于你想要为每个构建配置明确指定的内容。

I have a android gradle project where i have two buildTypes: QA and prod. I want to change a property in .properties file depending on the build type. I also want to change one of the value in settings.gradle file based on the buildType. I'm new to android and gradle so excuse me if this is a very basic question.

This is my .properties file:

build_number=3.1-SNAPSHOT
version_number=3.1.0
environment_name=prod //this needs to changed to environment_name=qa in qa environment

This is my settings.gradle file:

rootProject.name = 'tom-android-prod' //this needs to changed to rootProject.name = 'tom-android-qa' in qa environment

This is my build.gradle file:

apply plugin: 'com.android.application'

buildscript {
    repositories {
        jcenter()

    }

    dependencies {

    classpath 'com.android.tools.build:gradle:1.3.1'

    }
}


android {
    compileSdkVersion 21
    buildToolsVersion "21.1.0"

    defaultConfig {
        multiDexEnabled true
    }

    dexOptions {
        javaMaxHeapSize "4g"
    }

    packagingOptions {
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/license.txt'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/NOTICE.txt'
        exclude 'META-INF/notice.txt'
        exclude 'META-INF/ASL2.0'
    }

    configurations {
        all*.exclude group: 'com.android.support', module: 'support-v4'
    }

}

dependencies {
....
}

解决方案

I'm not real sure what your goal is with the environment_name as its not used, but imagine you need to set a variable only for a specific build then you could do something like this:

ext {
    environment_name = null
}
android {
    // other stuff...
    buildTypes {
        qa {
            project.ext.environment_name = "qa"
        }
        prod {
            project.ext.environment_name = "prod"
        }
    }
}

// later you can use the variable like this
println "Hello variable: $project.ext.environment_name"

Using buildTypes should remove the need to modify the rootProject.name = 'tom-android'. Or you could use the productFlavors closure in the same way... depends on what all you want to specify explicitly for each build configuration.
