Question

我在Kotlin开了一个新应用程序，但是当Android Studio完成构建新项目等等时，就说可以下载正确版本的Kotlin：

这是构建gradle：

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

buildscript {
    ext.kotlin_version = '1.1.4-eap-77'
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0-beta2'
        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
}

和app gradle：

apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.1"
    defaultConfig {
        applicationId "com.xxxxxx.xxxxxx"
        minSdkVersion 20
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"
    implementation 'com.android.support:appcompat-v7:26.0.1'
    implementation 'com.android.support:design:26.0.1'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.0'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.0'
}

如何修复它以允许下载正确的版本？

要使用kotlin插件的EAP版本，您必须在buildscript块中添加回购

maven {
            url 'https://dl.bintray.com/kotlin/kotlin-eap-1.1'
      }

类似的东西：

buildscript {
    ext.kotlin_version = '1.1.4-eap-77'
    repositories {
        google()
        jcenter()
        maven {
              url 'https://dl.bintray.com/kotlin/kotlin-eap-1.1'
        }
    }
    //...
}

此外，您应该将相同的maven repo添加到repository块以下载kotlin依赖项。

类似的东西：

repositories {
    google()
    jcenter()
    maven {
        url 'https://dl.bintray.com/kotlin/kotlin-eap-1.1'
    }
}
