body: <p>i have started having a problem with my project. Whenever I set source and target capability in my build.gradle file to java version 1_8 my project can't compile. </p>
  
  <p>Heres build.gradle code</p>
  
  <pre><code>buildscript {
      repositories {
          jcenter()
      }
      dependencies {
          classpath 'com.android.tools.build:gradle:1.5.0'
      }
  }
  apply plugin: 'com.android.application'
  
  repositories {
      jcenter()
  }
  
  android {
      compileSdkVersion 22
      buildToolsVersion "23.0.1"
  
      defaultConfig {
          applicationId "xxxx"
          minSdkVersion 22
          targetSdkVersion 22
          versionCode 1
          versionName "1.0"
      }
  
      compileOptions {
          sourceCompatibility JavaVersion.VERSION_1_8
          targetCompatibility JavaVersion.VERSION_1_8
      }
      buildTypes {
          release {
              minifyEnabled false
              proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
          }
      }
  }
  
  dependencies {
