无法解决：多模块 Kotlin 项目的 org.jetbrains.kotlin:kotlin-stdlib-jre8:1.2.71 错误

Question

I'm using Android Studio version 3.2 and I have a multi-module Gradle build.

I have a file called dependencies.gradle that looks like this:

   ext{
  //Android
  androidBuildToolsVersion = "26.0.0"
  androidMinSdkVersion = 21
  androidTargetSdkVersion = 26
  androidCompileSdkVersion = 26
  kotlinVersion = '1.2.71'

  //Libraries
  supportLibraryVersion = '26.1.0'
  rxJavaVersion = '2.2.0'
  javaxAnnotationVersion = '1.0'
  javaxInjectVersion = '1'
  rxKotlinVersion = '2.2.0'
  androidAnnotationsVersion='21.0.3'
  daggerVersion = '2.14.1'


  //Testing
  jUnitVersion = '4.12'
  assertJVersion = '3.11.0'
  mockitoKotlinVersion ='2.0.0-RC2'
  robolectricVersion = '3.4.2'

  domainDependencies = [
      javaxAnnotation: "javax.annotation:jsr250-api:${javaxAnnotationVersion}",
      javaxInject: "javax.inject:javax.inject:${javaxInjectVersion}",
      rxJava: "io.reactivex.rxjava2:rxkotlin:${rxJavaVersion}"
  ]

  domainTestDependencies = [
      junit: "junit:junit:${jUnitVersion}",
      mockito: "com.nhaarman.mockitokotlin2:mockito-kotlin:${mockitoKotlinVersion}",
      assertj: "org.assertj:assertj-core:${assertJVersion}"
  ]

  dataDependencies = [
      rxKotlin: "io.reactivex.rxjava2:rxkotlin:${rxKotlinVersion}",
      javaxAnnotation: "javax.annotation:jsr250-api:${javaxAnnotationVersion}",
       kotlin:    "org.jetbrains.kotlin:kotlin-stdlib-jre8:${kotlinVersion}",
      javaxInject: "javax.inject:javax.inject:${javaxInjectVersion}",
  ]

  dataTestDependencies = [
      junit: "junit:junit:${jUnitVersion}",
      kotlinJUnit: "org.jetbrains.kotlin:kotlin-test-junit:${kotlinVersion}",
      mockito: "com.nhaarman.mockitokotlin2:mockito-kotlin:${mockitoKotlinVersion}",
      assertj: "org.assertj:assertj-core:${assertJVersion}",
      robolectric: "org.robolectic:robolectric:${robolectricVersion}"
  ]

}

I want to write tests for the Data Module in my app and my build.gradle for the Data module is as follows.

apply plugin: 'kotlin'

dependencies {
    compile project(':Domain')

    def dataDependencies = rootProject.ext.dataDependencies
    def dataTestDependencies = rootProject.ext.dataTestDependencies



    implementation dataDependencies.javaxAnnotation
    implementation dataDependencies.javaxInject
    implementation dataDependencies.rxKotlin
    implementation dataDependencies.kotlin

    testImplementation dataTestDependencies.junit
    testImplementation dataTestDependencies.mockito
    testImplementation dataTestDependencies.assertj
    testImplementation dataTestDependencies.kotlinJUnit


}

sourceCompatibility = "1.8"
targetCompatibility = "1.8"

But when I sync my Gradle file I get the following errors from Android Studio.

• Failed to resolve: org.jetbrains.kotlin:kotlin-stdlib-jre8:1.2.71
• Failed to resolve: org.jetbrains.kotlin:kotlin-test-junit:1.2.71

Would really appreciate some help on this, as I'm sure I have the right package names. Thanks in advance

Add this to the build.gradle in the app folder implementation group: 'org.jetbrains.kotlin', name: 'kotlin-stdlib', version: '1.2.0' This solve my problem..

in your case change the version: implementation group: 'org.jetbrains.kotlin', name: 'kotlin-stdlib', version: '1.2.71'
