添加Java 8支持时Android Gradle构建失败

android gradle

添加Java 8支持时Android Gradle构建失败,android,gradle,android-gradle-plugin,android-gradle-3.0,Android,Gradle,Android Gradle Plugin,Android Gradle 3.0,在我的Android项目中，我使用的是gradle3.1，我添加了minifyEnabled true和配置proguard规则，当我使用/gradlew clean build项目构建时，没有错误。但后来我将Java1.8支持添加到gradle中，然后该项目的构建开始失败。还有一次，我通过删除sourceCompatibility JavaVersion.VERSION\u 1\u 8和targetCompatibility JavaVersion.VERSION\u 1\u 8删除了对jav

在我的Android项目中，我使用的是gradle3.1，我添加了

minifyEnabled true

和配置proguard规则，当我使用

/gradlew clean build

项目构建时，没有错误。但后来我将Java1.8支持添加到gradle中，然后该项目的构建开始失败。还有一次，我通过删除

sourceCompatibility JavaVersion.VERSION\u 1\u 8

和

targetCompatibility JavaVersion.VERSION\u 1\u 8

删除了对java 8的支持，项目使用

/gradlew clean build

进行构建。如何解决此问题

我的build.gradle文件如下

apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'

buildscript {
    repositories {
        mavenCentral()

我的前进规则如下所示

# Add project specific ProGuard rules here. # You can control the set of applied configuration files using the # proguardFiles setting in build.gradle. # # For more details, see # http://developer.android.com/guide/developing/tools/proguard.html # If your project uses WebView with JS, uncomment the following # and specify the fully qualified class name to the JavaScript interface # class: #-keepclassmembers class fqcn.of.javascript.interface.for.webview { # public *; #} # Uncomment this to preserve the line number information for # debugging stack traces. #-keepattributes SourceFile,LineNumberTable # If you keep the line number information, uncomment this to # hide the original source file name. #-renamesourcefileattribute SourceFile -dontwarn java.lang.invoke.* # Google -keep class android.support.v7.widget.** { *; } -keep interface android.support.v7.widget.** { *; } -keep class android.support.v4.app.** { *; } -keep interface android.support.v4.app.** { *; } # Platform calls Class.forName on types which do not exist on Android to determine platform. -dontnote retrofit2.Platform # Platform used when running on Java 8 VMs. Will not be used at runtime. -dontwarn retrofit2.Platform$Java8 # Retain generic type information for use by reflection by converters and adapters. -keepattributes Signature # Retain declared checked exceptions for use by a Proxy instance. -keepattributes Exceptions -keep class com.rxtest.proguard.network.** { *; } # OkHttp -dontwarn org.codehaus.** -dontwarn okhttp3.** -dontwarn okio.** #Retrofit -dontwarn retrofit.** -keep class retrofit.** { *; } -keepattributes Signature -keepattributes Exceptions -keepattributes *Annotation* -keep class com.facebook.** { *; } -keepclasseswithmembers class * { @retrofit2.http.* <methods>; } #Stetho -keep class com.facebook.stetho.** { *; }

当我构建项目时，我从终端接收到堆栈跟踪，如下所示
