找不到Gradle DSL方法：“versionCode()”

Question

在构建我的Android项目时遇到问题。我在gradle中使用Grgit填充versionCode和versionName。一切都很好，直到我将Android Studio和gradle工具更新到更新版本(build 3.4.0和发行版5.1.1)。

./gradlew build失败并显示错误：

* 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
, renderscriptNdkModeEnabled=null, versionCode=null, versionName=null, applicationId=null, testApplicationId=null, testInstrumentationRunner=null, testInstrumentationRunnerArguments={}, testHandleProfiling=null, testFunctionalTest=null, signingConfig=null, resConfi
g=null, mBuildConfigFields={}, mResValues={}, mProguardFiles=[], mConsumerProguardFiles=[], mManifestPlaceholders={}, mWearAppUnbundled=null} of type com.android.build.gradle.internal.dsl.ProductFlavor.

提供外部变量的脚本(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

/**
 * git.describe()
 *
 * Find the most recent tag that is reachable from HEAD. If the tag points to the commit,
 * then only the tag is shown. Otherwise, it suffixes the tag name with the number of additional
 * commits on top of the tagged object and the abbreviated object name of the most recent commit.

ext {
    git = Grgit.open(currentDir: projectDir)
    gitVersionName = git.describe(tags: true)
    gitVersionCode = git.tag.list().size()
    gitVersionCodeTime = git.head().time
}

task printVersion() {
    println("Version Name: $gitVersionName")
    println("Version Code: $gitVersionCode")
    println("Version Code Time: $gitVersionCodeTime")
}

任务./gradlew printVersion运行良好并显示：

Version Name: v0.6.2-42-g5e33c1a
Version Code: 5
Version Code Time: 1555447320

模块build.gradle文件：

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-kapt'
apply plugin: 'kotlin-android-extensions'
apply plugin: 'io.fabric'
apply from: "$project.rootDir/tools/script-git-version.gradle"

// Create a variable called keystorePropertiesFile, and initialize it to your
// keystore.properties file, in the rootProject folder.
def keystorePropertiesFile = rootProject.file("$project.rootDir/tools/keystore.properties")

// Initialize a new Properties() object called keystoreProperties.
def keystoreProperties = new Properties()

// Load your keystore.properties file into the keystoreProperties object.
keystoreProperties.load(new FileInputStream(keystorePropertiesFile))

android {
    compileSdkVersion 28
    buildToolsVersion '28.0.3'

        minSdkVersion 21
        targetSdkVersion 28
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    ..

    flavorDimensions "build"
    productFlavors {

            versionName gitVersionName
            dimension "build"
            applicationIdSuffix ".dev"
        }

        prod {
            versionCode gitVersionCode
            versionName gitVersionName
            dimension "build"
        }
    }
}

版本代码使用.toInteger()解决。

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

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