@andxu please work with the users to dig out more details on their project settings and find ways to reproduce. I see multiple reports here.

[andxu]

Cannot repro on my machine, @ZZYSonny, could you please try to upgrade the latest debugger version 0.6.0 and modify the launch.json to see if this bug eliminates:

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "java",
            "name": "Project_Main",
            "request": "launch",
            "mainClass": "Main",
            "args": ""
        }
    ]
}

[andxu]

@baodng could you please help us to provide the following command results for us:

tree <your project root> 
echo $JAVA_HOME

@jaylee185 Can you reproduce this issue? Then can you take this try:

1. Modify your launch.json#console from internalConsole to integratedTerminal
2. Press F5 and save the command line text from TERMINAL output view

1. Change the command line from sever=n to server=y and the port after address= to an random port(please choose a port which not occupied by your system) and run it in your system terminal, please give use the snapshot of command in your system terminal, like:

Hi Andy,

Never mind. I think it works for me now. I wasn’t under the complete
folder. Once I used code . from complete folder. Spring boot is able to
start.

Thanks,
Jay

[andxu]

then it looks like gethostbyname command of 'localhost' failed, check the content of /etc/hosts for the following statement:
127.0.0.1 localhost

[mukteshkrmishra]

I am still facing the same issue.

[RishabhTayal]

Having the same issue.

[Palidino]

A recent update seems to have brought this on. Can confirm it's happening on both Mac and windows for myself and another user under my project (no significant changes to the code or launch.json file since the last time the project was worked on a few days ago). Updating to the latest JDK 8 does not resolve the issue.

[aridastidar]

Can reproduce this issue with the latest release (and the following config) -

Version: 1.38.0
Commit: 3db7e09f3b61f915d03bbfa58e258d6eee843f35
Date: 2019-09-03T21:47:00.464Z
Electron: 4.2.10
Chrome: 69.0.3497.128
Node.js: 10.11.0
V8: 6.9.427.31-electron.0
OS: Darwin x64 18.7.0

The process just dies with the following message -

ERROR: transport error 202: recv failed during handshake: Connection reset by peer
ERROR: JDWP Transport dt_socket failed to initialize, TRANSPORT_INIT(510)
JDWP exit error AGENT_ERROR_TRANSPORT_INIT(197): No transports initialized [debugInit.c:750]

[ChrisWeissmann]

This happend to me after Spring boot told me to add it to hosts. Such as described here: https://stackoverflow.com/questions/33289695/inetaddress-getlocalhost-slow-to-run-30-seconds

And for some reason I thought it was a good idea to replace localhost with the my macbook name. It sped up my startup but I couldn't debug with the mentioned error. The etc/hosts file should have both localhost and the local name.
such as: 127.0.0.1 localhost my-mac.local

[joydeba]

I simply did
rm ~/.config/Code/User/settings.json
and it worked for me.
