Android Jack：来自jar文件的Lambda需要在类路径上编译接口，未知接口是java.util.function.Consumer [英] Android Jack: Lambda coming from jar file need their interfaces on the classpath to be compiled, unknown interfaces are java.util.function.Consumer

问题描述

在android studio 2.2上获取此功能。

Getting this on android studio 2.2.

有没有人有解决方法？

我的应用构建文件是：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.2"

    defaultConfig {
        applicationId "acme.cb2"
        minSdkVersion 18
        targetSdkVersion 24
        versionCode 1
        versionName "1.0"
        jackOptions {
            enabled true
        }

    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:24.1.1'
    compile 'com.android.support:support-v4:24.1.1'
}

编辑：修改主构建文件以包含来自 https://stackoverflow.com/users/5753091的答案/ mohammadreza-khalifeh - 但这没有帮助

edit: modifid the main build file to include answer from https://stackoverflow.com/users/5753091/mohammadreza-khalifeh - but this did not help

import java.text.SimpleDateFormat

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.0'
        classpath 'org.hidetake:gradle-ssh-plugin:2.4.2'

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

allprojects {
    repositories {
        jcenter()
    }
    gradle.projectsEvaluated {
        tasks.withType(JavaCompile) {
            options.compilerArgs << "-Xbootclasspath/a:" + System.properties.get("java.home") + "/lib/rt.jar"
        }
    }
}

编辑：添加：

options.compilerArgs.each { println 'option: '+it}

打印出来：

option: -Xbootclasspath/a:C:\Program Files\Java\jdk1.8.0_92\jre/lib/rt.jar

看起来路径中的空格可能会导致问题？

It looks like the space in the path might cause a problem?

编辑：尝试：

options.compilerArgs << "\""+"-Xbootclasspath/a:" + System.properties.get("java.home") + "/lib/rt.jar"+"\""

也不起作用。

推荐答案

将 Guava 库添加到我的依赖项后，我遇到了这个问题。

I had this problem after adding Guava library to my dependencies.

解决方案是从<$ c降级lib版本$ c> com.google.guava：guava：21.0 到 com.google.guava：guava：20.0 。

另外，我正在使用classpath'com.android.tools.build：gradle：2.5.0-alpha-preview-01`

Also, I'm using classpath 'com.android.tools.build:gradle:2.5.0-alpha-preview-01`

编辑：由于您不使用此库，请尝试在项目<$ c中更改：

As you don't use this library please try to change:

• $ c> build.gradle
  
  
  
  
  • 来自 classpath的类路径'com.android.tools.build:gradle ：2.2.0'到 com.android.tools.build:gradle:2.5.0-alpha-preview-01
  
  
  • in project build.gradle
    • classpath from classpath 'com.android.tools.build:gradle:2.2.0' to com.android.tools.build:gradle:2.5.0-alpha-preview-01

    在应用 build.gradle

    
    
    • 来自 compileSdkVersion 24 到 25
    
    
    • 来自 buildToolsVersion24.0.2到 25.0.2
    
    
    • from compileSdkVersion 24 to 25
    • from buildToolsVersion "24.0.2"to 25.0.2

    in gradle-wrapper.properties

    
    
    • 将版本更改为 distributionUrl = https： //services.gradle.org/distributions-snapshots/gradle-3.5-20170213202653+0000-all.zip

    
    
    • change version to distributionUrl=https://services.gradle.org/distributions-snapshots/gradle-3.5-20170213202653+0000-all.zip
