android - transformClassesWithDesugarForDebug 出错

Question

我在编译 APK(调试或发布)时遇到问题。

Android Studio 3.0 测试版 5

这是我的build.gradle(应用)

buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
    }

    dependencies {
        classpath 'io.fabric.tools:gradle:1.+'
    }
}

repositories {
    maven { url 'https://maven.fabric.io/public' }
}

apply plugin: 'com.android.application'
apply plugin: 'io.fabric'

        targetSdkVersion 26
        final MAJOR_RELEASE = 0
        final MINOR_RELEASE = 29
        versionCode getVersionCodeNumber(MAJOR_RELEASE, MINOR_RELEASE)
        versionName getVersionCodeName(MAJOR_RELEASE, MINOR_RELEASE)

        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        proguardFiles fileTree(dir: 'proguard', include: ['*.pro']).asList().toArray()
    }

    signingConfigs {
       omitted
    }

    buildTypes {

        jcenter()
        google()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir

这是我在编译时遇到的错误

我已经搜索并阅读了所有关于 desugar 错误的页面，但我找不到我的项目有什么问题。我也不明白为什么他在寻找 io.reactivex.Observable 有时是 io.reactivex.Flowable，而我正在使用 RxJava1 ，而不是 RxJava2。

Answer 1

在 gradle.properties 文件中添加 android.enableD8.desugaring = true。
