Gradle编译打包小结

以前用Eclipse打包，比较笨，右键导出签名
现在一直是用的Android Studio来开发
用Gradle编译打包非常方便
笔者整理的平时编译打包的配置，记录一下，避免遗忘
1.自动签名
可以直接写在build.gradle里，如:

signingConfigs {        develop {            storeFile '/xxxxxx/xxx.jks'            keyAlias 'xxxxxx'            keyPassword 'xxxxxx'            storePassword 'xxxxxx'        }    }

笔者习惯写在配置文件里，然后加入ignore方便后续更改

/** * 读取签名 * @return */def getSignProperty() {    def Properties buildProperties = new Properties()    buildProperties.load(new FileInputStream(file('../config/sign.properties')))    return buildProperties}

签名配置sign.properties

STORE_PASSWORD=xxxxxxKEY_PASSWORD=xxxxxxKEY_ALIAS=xxxxxxSTORE_FILE=xxxxxx.jks

2.同时打出不同环境的包
正常情况下一个项目可能同时有测试环境和正式环境
如果每次打包都去改配置是非常繁琐的，而且容易出错
建议在配置文件里直接添加配置

productFlavors {        buildDevelop {            buildConfigField "boolean", "MODEL_DEV", "true"            versionName = mVersionName        }        buildRelease {            buildConfigField "boolean", "MODEL_DEV", "false"            versionName = mVersionName        }    }

如上所述，打包的时候会同时打出两个不同的包，一个是测试环境一个是正式环境

3.输出日志
记录打包时候的时间，版本号以及Git提交的版本等等，方便日后审查

/** * 输出日志 */def buildLog(String output,String vName,String vCode) {    File outputFile = new File(output)    if(!outputFile.exists())        outputFile.mkdirs()    FileWriter fw = new FileWriter(output + File.separator + "log.txt")    StringBuilder builder = new StringBuilder();    builder.append("[构建时间]=" + buildTime("yy-MM-dd HH:mm"))    builder.append("\r\n")    builder.append("[版本编号]=" + vCode)    builder.append("\r\n")    builder.append("[版本名称]=" + vName)    builder.append("\r\n")    builder.append("[提交记录]=" + getGitVersion())    fw.write(builder.toString())    fw.flush();    fw.close();}

相关的函数

/** * 读取Git日志 * @return */def getGitVersion() {    return 'git rev-parse --short HEAD'.execute().text.trim()}/** * 构建时间 * @return */def buildTime(String time) {    def date = new Date()    def formattedDate = date.format(time)    return formattedDate}

4.编译构建完成之后最好备份一下mapping文件

build {    doLast {        //记录日志        buildLog(mOutputs,mVersionName,mVersionProps['VERSION_CODE'])        //复制文件        copy {            from "$buildDir/outputs/mapping"            into mOutputs        }    }}

最后的全局配置文件

apply plugin: 'com.android.application'/** * 读取版本配置 */def Properties mVersionProps = getVersionProperty();/** * 读取版本名 */def mVersionName = buildRelease() ? mVersionProps['VERSION_NAME'] : "build_" + buildTime('yyMMdd')/** * 输出目录 */def mOutputs = "$rootDir/outputs/build_" + buildTime('yyMMdd')android {    signingConfigs {        develop {            def Properties buildSignProps = getSignProperty()            storeFile file(buildSignProps['STORE_FILE'])            keyAlias buildSignProps['KEY_ALIAS']            keyPassword buildSignProps['KEY_PASSWORD']            storePassword buildSignProps['STORE_PASSWORD']        }    }    buildTypes {        debug {            applicationIdSuffix ".debug"            buildConfigField "boolean", "MODEL_DEV", "true"        }        release {            minifyEnabled true            buildConfigField "boolean", "MODEL_DEV", "false"            signingConfig signingConfigs.develop            zipAlignEnabled true            //去掉无用资源            shrinkResources true            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'        }    }    //读取版本配置    compileSdkVersion 23    buildToolsVersion "23.0.2"    defaultConfig {        applicationId "cn.byhook.main"        minSdkVersion 9        targetSdkVersion 23        versionCode Integer.valueOf(mVersionProps['VERSION_CODE'])        versionName = mVersionName    }    dexOptions {        javaMaxHeapSize "4g"    }    lintOptions {        checkReleaseBuilds false        abortOnError false    }    compileOptions {        sourceCompatibility JavaVersion.VERSION_1_7        targetCompatibility JavaVersion.VERSION_1_7    }    productFlavors {        /*_$ { variant.productFlavors.get(0).name }        $ { variant.buildType.name }*/        buildDebug {            buildConfigField "boolean", "MODEL_DEV", "true"            versionName = "Local Version"        }        buildDevelop {            buildConfigField "boolean", "MODEL_DEV", "true"            versionName = mVersionName        }        buildRelease {            buildConfigField "boolean", "MODEL_DEV", "false"            versionName = mVersionName        }    }    if (buildRelease()) {        android.variantFilter { variant ->            if (variant.buildType.name.equals('release')) {                variant.getFlavors().each() { flavor ->                    if (flavor.name.equals('buildDebug')) {                        variant.setIgnore(true);                    }                }            }        }    }    //输出文件配置    applicationVariants.all { variant ->        variant.outputs.each { output ->            def outputFile = output.outputFile            if (outputFile != null && outputFile.name.endsWith('.apk')) {                if ("release".equals(variant.buildType.name)) {                    if ("buildDevelop".equals(variant.productFlavors.get(0).name)) {                        output.outputFile = new File(                                mOutputs,                                "Main_${buildTime("yyMMddHHmm")}_dev.apk")                    } else if ("buildRelease".equals(variant.productFlavors.get(0).name)) {                        output.outputFile = new File(                                mOutputs,                                "Main_${buildTime("yyMMddHHmm")}.apk")                    }                } else {                    output.outputFile = new File(                            outputFile.parent,                            "app-debug.apk")                }            }        }    }}dependencies {    compile fileTree(dir: 'libs', include: ['*.jar'])    testCompile 'junit:junit:4.12'    testCompile 'org.robolectric:robolectric:3.1'    compile project(':Exlibrary')}/******************************************************************** * 打包脚本 ********************************************************************//** * 构建版本 * @return */def getVersionProperty() {    def Properties buildProps = new Properties()    buildProps.load(new FileInputStream(file('../config/version.properties')))    return buildProps;}/** * 读取签名 * @return */def getSignProperty() {    def Properties buildProperties = new Properties()    buildProperties.load(new FileInputStream(file('../config/sign.properties')))    return buildProperties}/** * 构建时间 * @return */def buildTime(String time) {    def date = new Date()    def formattedDate = date.format(time)    return formattedDate}/** * 是否发布 * 发布为真 * 版本号自增 * @return */def buildRelease() {    return false}/** * 读取Git日志 * @return */def getGitVersion() {    return 'git rev-parse --short HEAD'.execute().text.trim()}/** * 输出日志 */def buildLog(String output,String vName,String vCode) {    File outputFile = new File(output)    if(!outputFile.exists())        outputFile.mkdirs()    FileWriter fw = new FileWriter(output + File.separator + "log.txt")    StringBuilder builder = new StringBuilder();

小结一下，方便以后打包处理更为方便，当然Gradle的强大之处远不止如此
