IONIC ISSUE无法解析org.jetbrains.kotlin：kotlin-stdlib：1.1.3-2

Question

I am trying to build and emulate an android app using IONIC framework, but I am facing some issues after running ionic cordova build android. Here are all the versions listed:

• OS: Windows 10 x64
• Ionic: 4.12.0
• Cordova: 8.1.2
• Gradle: 4.10.1

I also create a gradle.properties file in [project_name]\\platforms\\android where I specify the http and https settings for my proxy. The same I did in the gradle-wrapper.properties file.

ionic-v1 build [11:26:25] Invoking sass gulp task. cordova build android Android Studio project detected Running command: "C:\\Program Files\\nodejs\\node.exe" C:\\Users\\KAA1WA3\\Desktop\\ionic\\todo\\hooks\\after_prepare\\010_add_platform_class.js C:\\Users\\KAA1WA3\\Desktop\\ionic\\todo ANDROID_HOME=C:\\Users\\KAA1WA3\\Desktop\\androidSDK\\androidSDK JAVA_HOME=C:\\Program Files\\Java\\jdk1.8.0_181 studio Starting a Gradle Daemon, 2 stopped Daemons could not be reused, use --status for details Task :wrapper

Example to include kotlin plugin.

app/build.gradle
-----------------
apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.example.myapplication"
        minSdkVersion 25
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}
