Gradle bauen mit Java 1.8 fehlschlagen, bauen Tool 2.2.0-alpha4 aktivieren jackOptions

Question

Ich baue android Projekt mit gradle Config unter: Android Studio 2.1.2

Projekt gradle Datei:

dependencies { 
    classpath 'com.android.tools.build:gradle:2.2.0-alpha4' 
} 

App gradle Datei:

android { 
    compileSdkVersion 24 
    buildToolsVersion '24.0.0' 

    defaultConfig { 
     applicationId "<my_app_id>" 
     minSdkVersion 17 
     targetSdkVersion 24 
     versionCode 1 
     versionName "1.0" 

     jackOptions { 
      enabled true 
     } 
    } 
    compileOptions { 
     sourceCompatibility JavaVersion.VERSION_1_8 
     targetCompatibility JavaVersion.VERSION_1_8 
    } 
} 

Die App immer mit Fehlern fehlgeschlagen bauen:

Kann jemand mich in der richtigen Art und Weise zeigen, wie dieses Problem zu lösen ?, Bitte helfen Sie mir!

Danke,

Answer 1

Unsupported major.minor version 52.0 bedeutet, dass Sie die falsche Version von JDK verwenden. Sie müssen Ihr JDK auf Version 8 aktualisieren, da Sie Ihre JAVA-Sprachversion auf 1.8 setzen.

Herunterladen JDK 8 von Oracle:

Answer 2

ich auch das gleiche Problem konfrontiert, kann es durch folgende zwei Schritten gelöst werden:

Schritt 1: Download Java 8. Schritt 2: Update Android Studio auf die neueste Version 2.2.
