我尝试在Gradle文件中启用minifyEnabled true进行部署,但收到以下错误:

java.lang.IllegalArgumentException: Unable to create converter for class com.th3pl4gu3.mes.models.MesResponse
for method MesApiService.getServices

我的代码如下
AppContainer.kt

/**
 * Dependency Injection container at the application level.
 */
interface AppContainer {
    val onlineServiceRepository: ServiceRepository
}

/**
 * Implementation for the Dependency Injection container at the application level.
 *
 * Variables are initialized lazily and the same instance is shared across the whole app.
 */
class DefaultAppContainer(private val context: Context): AppContainer {
    private val BASE_URL = "https://..."

    /**
     * Use the Retrofit builder to build a retrofit object using a kotlinx.serialization converter
     */
    @OptIn(ExperimentalSerializationApi::class)
    private val retrofit: Retrofit = Retrofit.Builder()
        .addConverterFactory(Json.asConverterFactory("application/json".toMediaType()))
        .baseUrl(BASE_URL)
        .build()

    /**
     * Retrofit service object for creating api calls
     */
    private val retrofitService: MesApiService by lazy {
        retrofit.create(MesApiService::class.java)
    }
}

ServiceRepository.kt

/**
 * Repository that fetch service list from Mes API.
 */
interface ServiceRepository {
    /** Fetches list of services from Mes API */
    suspend fun getMesServices(): MesResponse
}

MesApiServiceRepository.kt

class MesApiServiceRepository(

    private val mesApiService: MesApiService

) : ServiceRepository {
    /** Fetches list of Services from Mes API */
    override suspend fun getMesServices(): MesResponse = mesApiService.getServices()
}

MesResponse.kt

@kotlinx.serialization.Serializable
data class MesResponse(
    val services: List<Service>,
    val message: String,
    val success: Boolean
)

有人能帮帮我吗?

我可以通过向MesResponse类添加@Keep来修复它。

@Keep
@kotlinx.serialization.Serializable
data class MesResponse(
    val services: List<Service>,
    val message: String,
    val success: Boolean
)
