android - Android Studio中的Kotlin

我正在从kotlin使用，但是当我在项目中同步它时，出现以下错误:

Error:Could not find org.jetbrains.kotlin:kotlin-gradle-plugin:1.1.2-3.
Searched in the following locations:

    project :

这是我的build.gradle(Module):

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.3"
    defaultConfig {
        applicationId "ir.baslam.kotlinme"
        minSdkVersion 16
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:25.3.1'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    testCompile 'junit:junit:4.12'
    compile "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"
}
repositories {
    mavenCentral()
}

这是我的build.gradle(project):

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    ext.kotlin_version = '1.1.2-3'
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

最佳答案

ext.kotlin_version = '1.1.2-3'

在jcenter repo中，'1.1.2-3'版本不可用，在文件系统中也不可用。

当我检查jcenter中提供的最新版本1.1.2-2时，该最新更新于2017年4月28日，因此请使用1.1.2-2版本而不是1.1.2-3。

ext.kotlin_version = '1.1.2-2'
