Question

在我的Android Studio 3.1.3上，新的项目与此buildscript { ext.kotlin_version = '1.2.50' repositories { google() jcenter() } dependencies { classpath 'com.android.tools.build:gradle:3.1.3' 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 }：

Outdated Kotlin Runtime
        Your version of Kotlin runtime in 'Gradle: org.jetbrains.kotlin:kotlin-stdlib:1.2.30@jar' library is 1.2.30-release-78 (1.2.30), while plugin version is 1.2.50-release-Studio3.1-1.
        Runtime library should be updated to avoid compatibility problems.
        Update Runtime Ignore

它给出以下警告消息：

app/build.gradle

升级过时的kotlin运行时库有哪些步骤？

我的apply plugin: 'com.android.application' apply plugin: 'kotlin-android' apply plugin: 'kotlin-android-extensions' android { compileSdkVersion 28 defaultConfig { applicationId "org.pilab.toxx" minSdkVersion 15 targetSdkVersion 28 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-v7:28.0.0-alpha3' implementation 'com.android.support.constraint:constraint-layout:1.1.2' implementation 'com.android.support:design:28.0.0-alpha3' testImplementation 'junit:junit:4.12' androidTestImplementation 'com.android.support.test:runner:1.0.2' androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2' }：

似乎您的build.gradle需要更改。这样做：

您使用的是stdlib-jre7而不是stdlib-jdk7，因为现在{strong>已弃用stdlib-jre7 ，这就是收到此警告的原因。

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation 'com.prolificinteractive:material-calendarview:1.4.0'
implementation 'com.android.support:appcompat-v7:27.0.0'
implementation 'com.android.support:multidex:1.0.3'
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'

 }

allprojects {
    repositories {
        maven { url "https://jitpack.io" }
        mavenCentral()
        google()
    }
