我从未遇到过的编译错误

Question

Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - Erroneous tree type: <any>
    at pkgfinal.Final.main

我以前从未遇到过此错误，我尝试过更改pkg详细信息，并且完全创建了一个新项目来尝试绕过此问题。

package pkgfinal;

import java.util.Scanner;
public class Final {

public static void main(String[] args) {
double child = 18.00;
double adult = 36.00;
double senior = 32.50;
double ticketTotal = 0;
double moneyTotal = 0;
int i = 0;

do {
    Scanner input = new Scanner(System.in);
    System.out.println("Choose your ticket type, Please press 1 for Child, 2 for Adult or 3 for Senior.");
            Scanner ticketType = new Scanner(System.in);
            double ticketType = input.nextdouble();
            System.out.println("Choose your ticket type, Please press 1 for Child, 2 for Adult or 3 for Senior.");
            Scanner ticketType = new Scanner(System.in);
            double ticketTotal = input.nextdouble();


        if (ticketType == 1) {
                ticketTotal = ("Child");
            } else if (ticketType == 2) {
                ticketTotal = ("Adult");
            } else if (ticketType == 3) {
                ticketTotal = ("Senior");
            } else {
            System.out.println("I'm sorry that is an invalid choice");
            System.out.println("Goodbye.");
            return;

我对其余的代码非常有信心，这是我尝试实现的简单票务系统，有人可以解释一下实际的问题吗？我刚刚更新了IDE，因为我在编写代码时没有注册错误，因此遇到了一些问题

谢谢。
