Getting error in retrolambda error in android studio 1.0

Question

I am working in android studio 1.0

the gradle file is showing this error:

Execution failed for task ':app:compileRetroLambdaDebug'

apply plugin: 'android'
apply plugin: 'retrolambda'

android {
compileSdkVersion 21
buildToolsVersion '19.1.0'
defaultConfig {
    applicationId "xxxxxxxx"
    minSdkVersion 10
    targetSdkVersion 21
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
 productFlavors {
}
compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
   }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:support-v4:21.0.2'
    compile 'com.android.support:appcompat-v7:21.0.2'
    compile 'io.reactivex:rxandroid:0.23.0'

}

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

buildscript {
    repositories {
        jcenter()
        mavenCentral()
    }
dependencies {
    classpath 'com.android.tools.build:gradle:1.0.0-rc1'
    classpath 'me.tatarka:gradle-retrolambda:2.4.1'

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
         jcenter()
         mavenCentral()
     } 
}

what else changes I have to make in the gradle file. Please suggest something...

Answer 1

I had a similar error while updating the dependencies in eclipse. Try to update to the newest plugin versions and change retrolambda to me.tatarka.retrolambda, since the retrolambda plugin is deprecated and will be removed soon. At least it's what I did to fix the error.

apply plugin: 'me.tatarka.retrolambda'
apply plugin: 'android'

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'me.tatarka:gradle-retrolambda:2.5.0'
        classpath 'com.android.tools.build:gradle:1.0.1'
    }
}
