Android 3.3.0 update, ERROR: Cause: invalid type c

问题:

After the new update of Android Studio (3.3.0) I'm getting error from Gradle sync saying "ERROR: Cause: invalid type code: 68". Even in project, that have been created before the update and hasn't changed at all. I've tried to reinstall Android Studio, which hasn't helped either, so there has to be something incompatible with my project, but it doesn't say what and why.

App gradle:

apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "cz.cubeit.cubeit"
        minSdkVersion 21
        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-jdk7:$kotlin_version"
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support:cardview-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    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'
    implementation 'com.android.support:support-v4:28.0.0'
    implementation 'com.android.support:design:28.0.0'
}

Project gradle:

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

buildscript {
    ext.kotlin_version = '1.3.11'
    ext.anko_version='0.10.7'
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.0'
        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
}

I had the same problem. I was working on a project on two PCs: one at my office and one at home. In my office, after the AS 3.3 update, everything was fine but at home, after the same steps that I did at office, the Error code 68 came out.

After a couple of hours I figured out how to solve it. Android Studio 3.3 has the "Only sync the active variant" option enabled by default in Settings>Experimental. Disabling this feature resolved the problem. But reactivating the feature the same error shows up, even after a successfull Gradle sync. So I think this isn't a complete solution, but at least now I can work.

I had the same issu with IntelliJ 2019.1, Untick this option works for me.

I had the same error (6C) during a LinkedIn Learning course, I managed to solve it through the following steps

• Updating Kotlin in project-level build.gradle file
• Update gradle build version in project-level build.gradle file.
• Open Project Structure and using the Suggestions tab, update all modules to the latest version.
• Update the compileSdkVersion & targetSdkVersion to latest.
