Android Studio 3 Kotlin版

Question

在啟動Android Studio 3 beta 2時，我收到以下消息：

“你的'kotlin-stdlib-1.1.4-2'庫中的Kotlin運行時版本是1.1.4-2，而插件版本是1.1.4-release-Studio3.0-3。應該更新運行時庫以避免兼容性問題。”

在buildscript （項目級gradle）中，我已經將ext.kotlin_version = '1.1.4-2'更改為ext.kotlin_version = '1.1.4-3'

我嘗試重建和清理項目但沒有工作，我仍然在開始時收到該消息。

Gradle項目級別：

buildscript {
ext.kotlin_version = '1.1.4-3'
ext.app_compat_version = '26.0.1'
ext.google_play_services = '11.2.0'
ext.firebase_ui_version = '2.1.1'
ext.retrofit_version = '2.3.0'

repositories {
    google()
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:3.0.0-beta3'
    // update kotlin to 1.1.4-2
    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
    classpath 'com.google.gms:google-services:3.1.0'
    classpath ('com.google.firebase:firebase-plugins:1.1.0'){
        exclude group: 'com.google.guava', module: 'guava-jdk5'
    }
}
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

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

Gradle app級別：

apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.1"
    defaultConfig {
        applicationId ""

Answer 1

好的，因為我刪除了測試依賴性：

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'

問題消失了，但我不知道為什么這樣不要問我。

Answer 2

你改變了嗎？

classpath 'com.android.tools.build:gradle:3.0.0-beta3'

因為有了這個類路徑，我們可以使用kotlin-version 1.1.4-3
