具有 gradle 额外属性的自动增量版本代码

Autoincrement VersionCode with gradle extra properties(具有 gradle 额外属性的自动增量版本代码)

问题描述

我正在使用 gradle 构建一个 Android 应用.到目前为止，我使用 Manifest 文件来增加 versionCode，但我想从外部文件中读取 versionCode，并根据它是发布风格还是调试风格来增加 versionCode.我尝试了额外的属性，但你无法保存它们，这意味着下次我构建它时，我会得到相同的 versionCode.任何帮助将不胜感激！

I'm building an Android app with gradle. Until now I used the Manifest file to increase the versionCode, but I would like to read the versionCode from an external file and depending if it is the release flavor or the debug flavor increase the versionCode. I tried the extra properties, but you can't save them, which means that next time I build it I'm getting the same versionCode. Any help would be very much appreciated!

project.ext{
    devVersionCode = 13
    releaseVersionCode = 1
}

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.6.+'
    }
}

apply plugin: 'android'

repositories {
    mavenCentral()
}

dependencies {
    compile project(':Cropper')
    compile "com.android.support:appcompat-v7:18.0.+"
    compile "com.android.support:support-v4:18.0.+"
    compile fileTree(dir: 'libs', include: '*.jar')
}

def getReleaseVersionCode() {
    def version = project.releaseVersionCode + 1
    project.releaseVersionCode = version
    println sprintf("Returning version %d", version)
    return version
}

def getDevVersionCode() {
    def version = project.devVersionCode + 1
    project.devVersionCode = version
    println sprintf("Returning version %d", version)
    return version
}


def getLastVersioName(versionCode) {
    return "0.0." + versionCode
}

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.0"

    defaultConfig {
        minSdkVersion 9
        targetSdkVersion 19
    }

    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }
    }

    buildTypes {
        release {
            runProguard true
            proguardFile getDefaultProguardFile('proguard-android-optimize.txt')
            proguardFile 'proguard.cfg'
            debuggable false
            signingConfig null
            zipAlign false
        }
        debug {
            versionNameSuffix "-DEBUG"
        }
    }
    productFlavors {
        dev {
            packageName = 'com.swisscom.docsafe.debug'
            versionCode getDevVersionCode()
            versionName getLastVersioName(project.devVersionCode)
        }
        prod {
            packageName = 'com.swisscom.docsafe'
            versionCode getReleaseVersionCode()
            versionName getLastVersioName(project.releaseVersionCode)
        }
    }
}

task wrapper(type: Wrapper) {
    gradleVersion = '1.8'
}

推荐答案

我想从外部文件中读取版本代码

I would like to read the versionCode from an external file

我确信有许多可能的解决方案；这是一个:

I am sure that there are any number of possible solutions; here is one:

android {
    compileSdkVersion 18
    buildToolsVersion "18.1.0"

    def versionPropsFile = file('version.properties')

    if (versionPropsFile.canRead()) {
        def Properties versionProps = new Properties()

        versionProps.load(new FileInputStream(versionPropsFile))

        def code = versionProps['VERSION_CODE'].toInteger() + 1

        versionProps['VERSION_CODE']=code.toString()
        versionProps.store(versionPropsFile.newWriter(), null)

        defaultConfig {
            versionCode code
            versionName "1.1"
            minSdkVersion 14
            targetSdkVersion 18
        }
    }
    else {
        throw new GradleException("Could not read version.properties!")
    }

    // rest of android block goes here
}

此代码需要一个现有的 version.properties 文件，您将在第一次构建之前手动创建该文件以具有 VERSION_CODE=8.

This code expects an existing version.properties file, which you would create by hand before the first build to have VERSION_CODE=8.

此代码只是在每次构建时增加版本代码 - 您需要扩展该技术以处理每个风味的版本代码.

This code simply bumps the version code on each build -- you would need to extend the technique to handle your per-flavor version code.
