Gradle सिंक त्रुटि 3.1 कैनरी 3

Question

अरे साथियों के बाद अद्यतन एंड्रॉयड स्टूडियो 3.1 कैनरी से 3 मैं सिर्फ ताजा परियोजना बना लिया है लेकिन Gradle तुल्यकालन कारण विफल:

Error:com.android.tools.idea.gradle.project.model.AndroidModuleModel.getMainArtifact()Lcom/android/tools/idea/gradle/project/model/ide/android/IdeAndroidArtifact;com.android.tools.idea.gradle.project.model.AndroidModuleModel.getMainArtifact()Lcom/android/tools/idea/gradle/project/model/ide/android/IdeAndroidArtifact;

मेरे Gradle फ़ाइल है:

> buildscript { 
>  ext.kotlin_version = '1.2.0-rc-39' 
>  repositories { 
>   google() 
>   jcenter() 
>   maven { url "https://dl.bintray.com/kotlin/kotlin-dev"} 
>  } 
>  dependencies { 
>   classpath 'com.android.tools.build:gradle:3.1.0-alpha03' 
>   classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" 
>   classpath 'com.google.gms:google-services:3.1.0'

>

Answer 1

एक ही समस्या यहाँ। कोटलिन प्लगइन को अनइंस्टॉल करना (प्राथमिकताएं> प्लगइन्स> कोटलिन> अनइंस्टॉल करें) और आईडीई के साथ आने वाले संस्करण का उपयोग करने से समस्या हल हो गई है।
