Gradle 无法用 java 1.8 编译

Question

我的项目开始出现问题。每当我将 build.gradle 文件中的源和目标功能设置为 java 版本 1_8 时，我的项目就无法编译。

这里是build.gradle代码

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 {
}

适用于 java 1.6

这是来自 gradle assembleDebug --stacktrace

的一些堆栈跟踪

编译器似乎出了点问题，不知道该怎么办。

我的 bash 个人资料，如果有什么关系的话

export GRADLE_HOME=/Users/xxx/Library/gradle-2.8/bin
export ANDROID_HOME=/Users/xxx/Library/Android/sdk
export ANDROID_NDK=/Users/xxx/Library/android-ndk
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk/Contents/Home
export PATH=${PATH}:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools:$GRADLE_HOME:$JAVA_HOME:$ANDROID_NDK

我尝试了不同的 gradle 版本 - 2.11、2.12、2.8。

我正在研究 IntelliJ15。尝试在模块设置中设置项目路径，还尝试将语言级别设置为 lambda。似乎没有任何效果。

Answer 1

Android 引入 java 8 仅与 Android N.

要使用 java 8，您需要：

Android Studio 2.1（预览版）
启用 jack 编译器

有点像：

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