Gradle DSL method not found: 'versionCode()'

问题

Have a problem build my Android project. I using Grgit to fill versionCode and versionName in gradle. Everything worked fine, until I updated Android Studio and gradle tools to newer version (build 3.4.0 and distribution 5.1.1).

./gradlew build fail and show error:

* What went wrong:
A problem occurred evaluating project ':app'.
> Could not find method versionCode() for arguments [1555447320] on ProductFlavor_Decorated{name=dev, dimension=null, minSdkVersion=null, targetSdkVersion=null, renderscriptTargetApi=null, renderscriptSupportModeEnabled=null, renderscriptSupportModeBlasEnabled=null

Script which provide externals (project/tools/script-git-version.gradle)

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        //previous: 'org.ajoberstar:grgit:1.5.0'
        classpath 'org.ajoberstar.grgit:grgit-gradle:3.1.1'
    }
}

import org.ajoberstar.grgit.Grgit

ext {

Solved using .toInteger() for version code.

productFlavors {
    dev {
        versionCode gitVersionCodeTime.toInteger()
        versionName gitVersionName
        dimension "build"
        applicationIdSuffix ".dev"
    }

    prod {
        versionCode gitVersionCode.toInteger()
        versionName gitVersionName
        dimension "build"
    }
}
