java.lang.NoClassDefFoundError：java / rmi / ConnectException

Question

在 ./gradlew run 中编写多平台应用程序工作正常，但在运行 ./gradlew runDistributable 后，使用 ktor 进行 api 调用时会出现异常

java/rmi/ConnectException

。 模块-

val provideKtorClient = module {
    single {
        HttpClient {
            expectSuccess = true
            install(ContentNegotiation) {
                json(Json {
                    prettyPrint = true
                    ignoreUnknownKeys = true
                })
            }

            install(HttpTimeout) {
                requestTimeoutMillis = 2000
            }

            HttpResponseValidator {
                handleResponseExceptionWithRequest { cause, _ ->
                    when (cause) {
                        is ClientRequestException -> {
                            val response: ErrorResponse = cause.response.body()
                            throw ServerExceptionResponse(response)
                        }
                    }
                }
            }
        }
    }
}

Progaurd 可能在尝试运行时删除了一些必要的东西

./gradlew packageForCurrentOS

有什么建议吗？出了什么问题！

当我尝试使用 ktor 调用 api 时的屏幕截图 -

在调试/开发模式下一切正常。

Answer 1

已解决

我正在导入

java.rmi.ConnectException

通过导入解决了问题

java.net.ConnectException

使用方法--

try {
  //Network call
} catch(e: ConnectException) {
   //Error
}

但仍有疑问！

但是为什么

java.rmi.ConnectException

在开发模式下工作而不是在发布模式下工作？
