android - Gradle 项目同步失败，Kotlin

Question

我使用的是 Beta Kotlin 和 Android-Studio channel 。更新到最新版本后，我遇到了一些 gradle 同步错误。

以下是我从事件日志中复制的日志:

Error:Could not find org.jetbrains.kotlin:kotlin-gradle-plugin:1.2.0-rc-39.
Searched in the following locations:

    project :

下面是build.gradle

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

buildscript {
    ext.kotlin_version = '1.2.0-rc-39'
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.0-alpha04'
        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 {
        google()
        jcenter()
    }
}

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

下面是应用程序build.gradle:

apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'

android {
    compileSdkVersion 26
    defaultConfig {
        applicationId "com.udebest.myapplication"
        minSdkVersion 15
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            postprocessing {
                removeUnusedCode false
                removeUnusedResources false
                obfuscate false
                optimizeCode false
                proguardFile 'proguard-rules.pro'
            }
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation"org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"
    implementation 'com.android.support:appcompat-v7:26.1.0'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.1'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
}

拜托，有人对此有想法吗？我真的不知道我该如何解决这个问题？我在那里找不到任何解决方案。

Answer 1

将 buildscript 和 allprojects 中的 repositories 更改为:

{
    google()
    jcenter()
    mavenCentral()
    maven {
        url 'https://dl.bintray.com/kotlin/kotlin-dev/'
    }
}

这对我有用。
