"Some Kotlin libraries attached to this project are in an unsupported format. Please update the libraries or plugin."

Question

I installed the kotlin plugin in my android studio project. The code does not correspond to the problem. It also executes when I call it from the java class. This gives me the warning "Some of the Kotlin libraries attached to this project are in an unsupported format. Please update the libraries or plugin." The println () function is also not recognized in the IDE.

test.kt

fun foo(){ println("ad") } public class iTar{ public fun printAll( vararg a: String ){ for(item in a)println(item) } } 

build.gradle

 buildscript { ext.kotlin_version = '0.8.679' repositories { mavenCentral() } dependencies { classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" } } apply plugin: 'com.android.application' apply plugin: 'kotlin-android' android { compileSdkVersion 20 buildToolsVersion "20.0.0" sourceSets { main.java.srcDirs += 'src/main/kotlin' } packagingOptions { exclude 'META-INF/LGPL2.1' exclude 'META-INF/LICENSE' exclude 'META-INF/NOTICE' } defaultConfig { applicationId "xxxxx" minSdkVersion 14 targetSdkVersion 20 versionCode 1 versionName "1.0" } buildTypes { release { runProguard false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } } dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) compile 'org.codehaus.jackson:jackson-mapper-lgpl:1.9.13' compile 'com.j256.ormlite:ormlite-android:4.48' compile 'org.mapsforge:svg-android:0.4.3' compile 'com.android.support:support-v4:20.+' compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version" } repositories { mavenCentral() }

Your problem is with using Kotlin 0.8.679 in your Gradle build, which is too new for the Kotlin plugin that you use in the IDE. Two possible solutions:

• upgrade your plugin to a newer nightly build or
• use the 0.8.11 command in your gradle build
