找不到JetBrains.Kotlin的实现参数

Question

我有一个Flutter项目，我正在使用一个二维码扫描器插件，这是为Android编写的Kotlin。在我的项目中添加了这个功能后，我在Android系统中遇到了构建问题，iOS系统运行良好：

我的应用程序分级：

buildscript {
    repositories {
        // ...
        maven { url 'https://plugins.gradle.org/m2/' } // Gradle Plugin Portal
    }

    // Added for QR
    apply plugin: 'com.android.application'
    apply plugin: 'kotlin-android'


    dependencies {

        // Added for QR
        implementation "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"
        // implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"


        // ...
        // OneSignal-Gradle-Plugin
        classpath 'gradle.plugin.com.onesignal:onesignal-gradle-plugin:[0.10.2, 0.99.99]'
    }
}

apply plugin: 'com.onesignal.androidsdk.onesignal-gradle-plugin'

def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
    flutterVersionCode = '1'
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
    flutterVersionName = '1.0'
}

apply plugin: 'com.android.application'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

def keystoreProperties = new Properties()
def keystorePropertiesFile = rootProject.file('key.properties')
if (keystorePropertiesFile.exists()) {
    keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
}

android {
    compileSdkVersion 27

    lintOptions {
        disable 'InvalidPackage'
    }

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "net.cadsys.app"
        minSdkVersion 16
        targetSdkVersion 27
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

    signingConfigs {
        release {
            keyAlias keystoreProperties['keyAlias']
            keyPassword keystoreProperties['keyPassword']
            storeFile file(keystoreProperties['storeFile'])
            storePassword keystoreProperties['storePassword']
        }
    }

    buildTypes {
        release {
            signingConfig signingConfigs.release
        }
    }
}

flutter {
    source '../..'
}

dependencies {
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

我的项目分级：

buildscript {
    ext.kotlin_version = '1.2.31'

    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

apply plugin: 'kotlin'

allprojects {
    repositories {
        google()
        jcenter()
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

task clean(type: Delete) {
    delete rootProject.buildDir
}
repositories {
    mavenCentral()
}
dependencies {
    compile "org.jetbrains.kotlin:kotlin-stdlib-jdk8:$kotlin_version"
}
compileKotlin {
    kotlinOptions {
        jvmTarget = "1.8"
    }
}
compileTestKotlin {
    kotlinOptions {
        jvmTarget = "1.8"
    }
}

任何帮助都会很好，因为我正要把我的笔记本电脑扔出窗外。

编辑：在AS提示后，我将Kotlin version变量更改为ext.kotlin_version='1.3.1'。我现在发现一个新错误：

Answer 1

buildScript {
    ext.kotlin_version = '1.3.31'
    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

您还可以在Kotlin Gradle Plugin上查看哪些插件可用。

替换：

implementation "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"

implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8:$kotlin_version"

implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"

如果您迫切需要JRE7(Deprecated)并且不推荐使用，请确保您的Kotlin版本与JRE版本匹配。
