我尝试克隆并构建此项目https://github.com/mitrejcevski/ui-testing,但是在Android Studio中打开该项目时,出现以下构建错误:
ERROR: The Android Gradle plugin supports only Kotlin Gradle plugin version 1.3.0 and higher.
The following dependencies do not satisfy the required version:
root project 'ui-testing' -> org.jetbrains.kotlin:kotlin-gradle-plugin:1.2.21
Affected Modules: app
但是,当我单击“ app”超链接时,我被带到模块级build.gradle
文件,其内容为
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
android {
compileSdkVersion 27
defaultConfig {
applicationId "nl.jovmit"
minSdkVersion 19
targetSdkVersion 27
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
productFlavors {
mock {
flavorDimensions "default"
}
prod {
flavorDimensions "default"
}
}
android.variantFilter { variant ->
if (variant.buildType.name == 'release' && variant.getFlavors().get(0).name == 'mock') {
variant.setIgnore(true)
}
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])

androidTestImplementation 'com.android.support.test:runner:1.0.1'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
testImplementation 'junit:junit:4.12'
}
与公认的ERROR: The Android Gradle plugin supports only Kotlin Gradle plugin version 1.3.0 and higher答案不同,我在Gradle文件的任何位置都看不到任何ext.kotlin_version
。
不过,我确实看到了以下警告:kotlin-stdlib-jre7
已过时:
但是,我尝试更改此设置,但仍然遇到相同的错误。我也尝试添加行
implementation 'org.jetbrains.kotlin:kotlin-gradle-plugin:1.3.21'
到dependencies
(如上面的屏幕快照所示),但这也不能避免错误。
有人知道如何解决此问题吗?我怀疑过时的Kotlin版本是此处依赖项之一的“子依赖项”,但无法找出哪个依赖项。

定义您的ext.kotlin_version
您的项目级别build.gradle应该如下所示。
buildscript {
ext.kotlin_version = '1.2.51'
ext.android_plugin_version = '3.2.1'
repositories {
google()
jcenter()
}
dependencies {
classpath "com.android.tools.build:gradle:$android_plugin_version"
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}

更改
org.jetbrains.kotlin:kotlin-stdlib-jre7:$ kotlin_version
代替
org.jetbrains.kotlin:kotlin-stdlib-jdk8:$kotlin_version

我也遇到了这个问题,并通过以下操作解决了该问题:
buildscript {
ext.kotlin_version = '1.3.10'
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.4.0'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
ext {
roomVersion = '1.0.0'
archLifecycleVersion = '1.1.0'
}
implementation"org.jetbrains.kotlin:kotlin-stdlib-jdk8:$kotlin_version"
我建造了,一切又恢复正常了。

buildscript {
ext.kotlin_version = '1.3.10' //put the version you just updated to
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.4.1'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
}

只需转到您的项目级别的构建文件 并更改以下内容
buildscript {
ext {
kotlin_version = '1.3.10'
support_version = '28.0.0-rc02'
room_version = '1.1.1'
arch_comp_version = '1.1.1'
}
}
只需将kotlin版本更新到1.3.10或更高版本即可修复它。

转到外部库/ Flutter插件/ ui_testing / android / build.gradle,并将ext.kotlin_version更改为LATEST_VERSION。
