While you are waiting for getting help, here are some tips to improve your experience:

Code is much easier to read if posted with syntax highlighting and proper formatting.

If nobody is calling back, that usually means that your question was not well asked and hence nobody feels confident enough answering. Try to use your time to elaborate, provide details, context, more code, examples and maybe some screenshots. With enough info, someone knows the answer for sure.

Don't forget to close your thread using the command </help-thread close:1027500463647621170> when your question has been answered, thanks.

Opening with independent cmd window:

[buoyant tusk]

what's the problem ?

[fluid siren]

here

[buoyant tusk]

but it seems to work no ? what is the problem ?

[fluid siren]

It works when i open a new terminal, and then type "java -jar PATH_TO_FILE.jar", but don't work when i try to put inside a bat file

[buoyant tusk]

which error do you get ?

[fluid siren]

Example:
inside the bat file:

java -jar target/knightstour.jar
PAUSE

Open and closes.

=-=-=-=-=-=-=-=

new terminal window:
"java -jar "C:\Users\User\Desktop\knightstour\knightstour.jar""

Works fine

[buoyant tusk]

open a terminal window

run the bat

tell me the error

[fluid siren]

ok

Works fine... That's weird...

It doesn't work only when I click to run

Apparently, when I click to play, it opens a new terminal on the sys32 folder

and tries to locate the jar inside this folder, but, of course, it fails

but when i specify the path it works fine

[buoyant tusk]

no, that's not what i see in the first video

[vague anvil]

Maybe because you're starting as administrator?

[buoyant tusk]

i saw it opening in the correct folder

[fluid siren]

that was a screenshot from 0:11

[fluid siren]

I'll see that

[vague anvil]

I didn't see the video before, Alathreon is correct

[buoyant tusk]

🤔

[vague anvil]

It does open in the right folder

[buoyant tusk]

weird

sometime it opens the right folder

[vague anvil]

The system32 is just where CMD lives

[buoyant tusk]

at the start of the video

[fluid siren]

i'm confused 😆

i'll just format my pc

too much logic

Better video 👇 👇

[buoyant tusk]

so weird

try start java -jar...

[fluid siren]

Nope..

[buoyant tusk]

what happens ?

[fluid siren]

opens another terminal then closes

[buoyant tusk]

what

[fluid siren]

Yeah.. 😆

No programming challenge will defeat this one

[true whale]

please share the jar

[buoyant tusk]

I doubt it is the jar tho, it seems like the command immediately fail without showing any error

[true whale]

why do u have start in ur bat?

remove that

[buoyant tusk]

cause I asked him to

to see if creating a cmd will still cause the same problem

[true whale]

fair. shouldn't be there

start will create another cmd and that one has no pause in it

hence the double window

[fluid siren]

I could send the github repository, but I think it wouldn't help

[buoyant tusk]

that's not the problem tho

[true whale]

opens another terminal then closes

its the cause of that issue. that's what i was replying to. cheers

[buoyant tusk]

it's an observation -_-

[buoyant tusk]

the problem is this

[true whale]

yeah but u can't read the error without a pause

[buoyant tusk]

and the pause doesn't work

[true whale]

the pause is not applying to the window created by start

[fluid siren]

this video is better, Zabuzard. This is the problem

[buoyant tusk]

please see the previous video

[true whale]

start "java -jar Foo.jar & pause"

or just without start

[buoyant tusk]

zabu please here ↑

[true whale]

im not sure why u want to keep discussing this with me. can i leave? lol

u got this

[fluid siren]

You can go, guys. Thank's for your support

I'll keep searching this

[buoyant tusk]

when he is running the bat from a terminal, it works
but when he is running by double clicking, it doesn't and immediately close

[buoyant tusk]

even without start and with a pause

which shouldn't happen

[true whale]

and uve checked that the jar doesn't run a new Process(...)?

[fluid siren]

Yep

[fluid siren]

Nop

It doesn't run a new process. It's a simple unfinished game

[vague anvil]

Can you share the source

[fluid siren]

But forget...

[vague anvil]

Just in case it's something there

[fluid siren]

This is getting too big hahah

ok

[fluid siren]

https://github.com/arthurbrenno/knights-tour

[true whale]

well. this is easy to debug locally as u shared the jar file

im on mobile, so I'm out

[vague anvil]

Probably a private repo, gives me a 404 😛

[fluid siren]

Oh yeah

1 sec

https://github.com/arthurbrenno/knights-tour

[true whale]

comment out the print in the clear console method

then try again

[fluid siren]

Ok

1 sec

Omg

lol

hahahhahah

worked

thanks

😆 👍

[true whale]

👍

[fluid siren]

clearConsole() was the problem. Problem solved lol

[true whale]

those ansi commands are interpreted differently per console

the first command u had there is supposed to move the cursor at top left and the second is supposed to clear everything from cursor to current print position

resulting in a clear

but seems that cmd just messed it up completely and closes

[vague anvil]

Still weird that it closed the window though

[true whale]

because cmd is just bad with ansi

[vague anvil]

I think it gets some support in more recent versions

But maybe that's bugged here

[true whale]

unsure. maybe powershell behaves better

[fluid siren]

Yep.

Didn't think about that..

I'll try to create a new method to do that

[true whale]

afaik cmd has no proper way to clear

[vague anvil]

cls

[true whale]

yeah but no ansi

have fun triggering cls from within Java

[fluid siren]

public final static void clearConsole()
{
    try
    {
        final String os = System.getProperty("os.name");
        
        if (os.contains("Windows"))
        {
            Runtime.getRuntime().exec("cls");
        }
        else
        {
            Runtime.getRuntime().exec("clear");
        }
    }
    catch (final Exception e)
    {
        //  Handle any exceptions.
    }
}

I've seen this in Stack.. But this "exec" method is outdated afaik

[icy solar]

Detected code, here are some useful tools:

[fluid siren]

lol

Thank you, guys.

[true whale]

ur welcome
