Moshi-Android Studio Canary Alpha12-ExternalSynthetic0被多次定义

问题描述

编辑：问题已在Android Studio Canary Alpha 13上解决

Kotlin: 1.4.10
Android Gradle Tool: 4.2.0-alpha12

我在项目中使用moshi时没有任何问题。但是，当我将Android Studio Canary从Alpha11升级到Alpha12之后，出现以下构建过程错误：

AGPBI: {"kind":"error","text":"Type com.mydomain.example.data.forecast.remote.response.GetForecastResponse$City-$$ExternalSynthetic0 is defined multiple times: /Users/mydomain/Projects/Example/app/build/intermediates/project_dex_archive/debug/out/com/mydomain/example/data/forecast/remote/response/GetForecastResponse$City.dex,/Users/mydomain/Projects/Example/app/build/intermediates/project_dex_archive/debug/out/com/mydomain/example/data/forecast/remote/response/GetForecastResponse$Forecast.dex","sources":[{"file":"/Users/mydomain/Projects/Example/app/build/intermediates/project_dex_archive/debug/out/com/mydomain/example/data/forecast/remote/response/GetForecastResponse$City.dex"}],"tool":"D8"}

这是我的moshi gradle定义：

implementation "com.squareup.moshi:moshi:1.9.3"
kapt "com.squareup.moshi:moshi-kotlin-codegen:1.9.3"

响应类如下：

import com.squareup.moshi.Json
import com.squareup.moshi.JsonClass

@JsonClass(generateAdapter = true)
data class GetForecastResponse(
    @Json(name = "cod") val code: String,@Json(name = "message") val message: Int,@Json(name = "cnt") val count: Int?,@Json(name = "list") val list: List<Forecast>?,@Json(name = "city") val city: City?,) {

    @JsonClass(generateAdapter = true)
    data class Forecast(
        @Json(name = "dt") val datetime: Long,@Json(name = "main") val main: ForecastMain,@Json(name = "weather") val weather: List<ForecastWeather>,@Json(name = "clouds") val clouds: ForecastClouds,@Json(name = "wind") val wind: ForecastWind,@Json(name = "visibility") val visibility: Int,@Json(name = "pop") val pop: Double,@Json(name = "sys") val sys: ForecastSys,@Json(name = "dt_txt") val dateText: String,)

    @JsonClass(generateAdapter = true)
    data class ForecastMain(
        @Json(name = "temp") val temperature: Double,@Json(name = "feels_like") val feelsLike: Double,@Json(name = "temp_min") val minTemperature: Double,@Json(name = "temp_max") val maxTemperature: Double,@Json(name = "pressure") val pressure: Double,@Json(name = "sea_level") val seaLevel: Double,@Json(name = "grnd_level") val groundLevel: Double,@Json(name = "humidity") val humidity: Double,@Json(name = "temp_kf") val kfTemperature: Double,)

    @JsonClass(generateAdapter = true)
    data class ForecastWeather(
        @Json(name = "id") val id: Long,@Json(name = "main") val main: String,@Json(name = "description") val description: String,@Json(name = "icon") val icon: String,)

    @JsonClass(generateAdapter = true)
    data class ForecastClouds(
        @Json(name = "all") val all: Int,)

    @JsonClass(generateAdapter = true)
    data class ForecastWind(
        @Json(name = "speed") val speed: Double,@Json(name = "deg") val degree: Double,)

    @JsonClass(generateAdapter = true)
    data class ForecastSys(
        @Json(name = "pod") val pod: String,)

    @JsonClass(generateAdapter = true)
    data class City(
        @Json(name = "id") val id: Int,@Json(name = "name") val name: String,@Json(name = "coord") val location: Location,@Json(name = "country") val country: String,@Json(name = "population") val population: Long,@Json(name = "timezone") val timezone: Long,@Json(name = "sunrise") val sunrise: Long,@Json(name = "sunset") val sunset: Long,)

    @JsonClass(generateAdapter = true)
    data class Location(
        @Json(name = "lat") val latitude: Double,@Json(name = "lon") val longitude: Double,)
}

有人对此有想法吗？

解决方法

这是Android Studio 4.2金丝雀12中D8编译器的错误。问题是http://issuetracker.google.com/169183194，应该在金丝雀13中修复。
