IntelliJ IDEA:为什么readLine()需要两个用户输入而不是使用Kotlin? [英] IntelliJ IDEA: Why is readLine() expecting two user inputs instead of one using Kotlin?

问题描述

我编写了一个简单的程序，该程序从控制台获取用户的输入，然后将其打印出来.但是，当用户输入输入时，它会请求第二个用户输入，并且仅读取第二个输入.

I wrote a simple program that takes the user's input from the console and then prints it. But when the user enters the input, it requests a second user input and only reads the second input.

代码:

fun main(args: Array<String>) {
    print("Enter text: ")
    val stringInput = readLine()!!
    println("Readed text: $stringInput")
}

控制台:

> Task :MainKt.main()
Enter text: FirstInput
SecondInput
Disconnected from the target VM, address: 'localhost:37282', transport: 'socket'
Connected to the target VM, address: '127.0.0.1:37264', transport: 'socket'
Readed text: SecondInput

我正在使用最新版本的IntelliJ IDEA.我不知道为什么会这样.我正在使用Windows.

I'm using the latest version of IntelliJ IDEA. I don't know why this is happening. I'm using Windows.

推荐答案

这似乎是IntelliJ内部控制台中的错误:请参见此票证(可通过此答案找到).

This seems to be a bug in IntelliJ's internal console: see this ticket (found via this answer).

(同一问题似乎也出现在此问题之后和这个问题.)

(The same issue also appears to be behind this question and this question.)

我不知道它是否涉及相同的问题，但是此答案建议在编辑配置菜单，然后再次将其更改回.

I don't know if it refers to the same problem, but this answer recommends changing the JRE options in the Edit Configurations menu, and then changing them back again.
