android project gradle packaged compilation error, suggesting android gradle tool support a minimum of gradle version 5.1.1. But I locally installed version is 4.5.1.

2, the command can play develop, produce two different versions. Build.gradle modify the project file:

    signingConfigs {
        debug {
            storeFile file('/Users/lishuaikang/.android/debug.keystore')
            storePassword 'android'
            keyAlias 'androiddebugkey'
            keyPassword 'android'
//            v1SigningEnabled true
//            v2SigningEnabled true
        }

        release {
            storeFile file('/Users/lishuaikang/Documents/release.keystore')
            storePassword 'android'
            keyAlias 'androidreleasekey'
            keyPassword 'android'
//            v1SigningEnabled true
//            v2SigningEnabled true
        }
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
            signingConfig signingConfigs.release
        }
        debug {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
            signingConfig signingConfigs.debug
        }
    }

Are arranged on the path to the certificate and password, and alias.
Packaging execute the command:

gradle assembleDebug 
gradle assembleRelease

They are the development version and a production version.
But it is given:

Failed to generate v1 signature

I do not know what out why.

Delete the old certificate and re-generate the certificate. All right.

3, certificate generation.
