build.gradle中使用Git提交记录

    //默认配置
    defaultConfig {
        applicationId "com.huyingbao.simple"
        multiDexEnabled true//支持Multidex分包
        minSdkVersion MIN_SDK_VERSION as int
        targetSdkVersion TARGET_SDK_VERSION as int
        versionCode gitGitVersionCode()
        versionName getGitVersionName()
        signingConfig signingConfigs.debug
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        vectorDrawables.useSupportLibrary = true//使用vector图片
        ndk { abiFilters "armeabi-v7a" }//配置ndk
        packagingOptions { exclude "lib/arm64-v8a/librealm-jni.so" }//ReactNative配置
