“无法打开调试器端口（本地主机：5005）：java.io.IOException “握手失败 - 连接提前关闭”

Question

I am using vagrant on Ubuntu OS 18.04, virtual box, Kubernetes,Gradle, and skaffold, I faced the same issue of: "Unable to open debugger port (localhost:5005): java.io.IOException "handshake failed - connection prematurally closed "

它工作正常，直到 windows 变成 11，之后我遇到了所有问题，我试图将它恢复到 10 但没有运气

我尝试的是：

1-在 vagrant 和本地机器上使 JDK (11.0.14) 相同。

2- JAVA_TOOL_OPTIONS=

"-agentlib:jdwp=transport=dt_socket,server=y,address=*:5005,suspend=n"

3-

在这里你可以找到远程调试的配置。

4- vagrant配置，还有一个文件叫

Vagrant.configure("2") do |config|
  config.vm.provider "virtualbox"
  config.vm.provision :shell, path: "./forward-port.sh", run: 'always'

config.vm.define :skaffold do |skaffold|
  skaffold.vm.box = "bento/ubuntu-18.04"
  skaffold.vm.network "forwarded_port", guest: 80, host: 8080, host_ip: "127.0.0.1"
  skaffold.vm.network "forwarded_port", guest: 443, host: 8443, host_ip: "127.0.0.1"
  skaffold.vm.network "forwarded_port", guest: 5005, host: 5005, host_ip: "127.0.0.1"
  skaffold.vm.network "forwarded_port", guest: 5006, host: 5006, host_ip: "127.0.0.1"
  skaffold.vm.network "forwarded_port", guest: 5007, host: 5007, host_ip: "127.0.0.1"
  skaffold.vm.network "forwarded_port", guest: 5008, host: 5008, host_ip: "127.0.0.1"
  skaffold.vm.network "forwarded_port", guest: 5009, host: 5009, host_ip: "127.0.0.1"

5-转发端口.sh

#!/bin/bash
#sudo iptables -t nat -I PREROUTING -p tcp --dport 3306 -j DNAT --to-destination 127.0.0.1:3306
#sudo iptables -t nat -I PREROUTING -p tcp --dport 6379 -j DNAT --to-destination 127.0.0.1:6379

sudo iptables -t nat -I PREROUTING -p tcp --dport 5005 -j DNAT --to-destination 127.0.0.1:5005
sudo iptables -t nat -I PREROUTING -p tcp --dport 5006 -j DNAT --to-destination 127.0.0.1:5006
sudo iptables -t nat -I PREROUTING -p tcp --dport 5007 -j DNAT --to-destination 127.0.0.1:5007
sudo iptables -t nat -I PREROUTING -p tcp --dport 5008 -j DNAT --to-destination 127.0.0.1:5008
sudo iptables -t nat -I PREROUTING -p tcp --dport 5009 -j DNAT --to-destination 127.0.0.1:5009
sudo iptables -t nat -I PREROUTING -p tcp --dport 5010 -j DNAT --to-destination 127.0.0.1:5010

6-运行此命令jdb -attach 5005
