JAR. files aren't running

[stoic knoll]

I tried installing java, jarfix, and a jar file onto my pc (linux mint of course) and none of them ran, I tried setting it to autorun prompt but i got the same results.

soooooo

[worldly harbor]

what kind of file are you trying to run

[stoic knoll]

jar files

[worldly harbor]

but you said something about mods, which hint that you may have tried to run minecraft mods THROUGH java INSTEAD of minecraft

so idk

[stoic knoll]

they should be jar files and i can use them 2 install the minecraft mod

they're jar files that are installers for the mods i use

but they don't run and i dont know how to install java

[worldly harbor]

have you ran those commands you were told in the general chat?

the sudo apt install openjdk-jre?

[stoic knoll]

i'll try them again

[worldly harbor]

if that doesn't work, check if it says anything about similar packages

[stoic knoll]

E: Package 'openjdk-jre' has no installation candidate

[granite mesa]

What exactly are you trying to do

[worldly harbor]

apparently trying to run minecraft mods

[granite mesa]

not what you think you need to do to get from A to B the actual goal

[worldly harbor]

does it not say anything about similar packages??

[stoic knoll]

Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Package openjdk-jre is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

[worldly harbor]

telling them that but idk, I wonder how are they running minecraft without Java

[granite mesa]

why don't you search for the name of the package instead of guessing what it is called

[worldly harbor]

try sudo apt search openjdk

[granite mesa]

hint literally type the word java in a terminal and press enter it will tell you java not found but can be installed with....

[worldly harbor]

I'm trying to help as an arch user, also they seem extremely noobie so yeah

[stoic knoll]

i installed linux mint 3-4 hours ago

[worldly harbor]

try the openjdk-21-jre

and run whatever you needed to again

do it through terminal if it doesn't open anything at all (java -jar filename)

[stoic knoll]

openjdk-21-jre: command not found

[worldly harbor]

sudo apt install openjdk-21-jre

[stoic knoll]

[worldly harbor]

now try to run the file

[granite mesa]

note intalling java doesn't mean you an click on jar files like exes

[stoic knoll]

how do i open jar files than

cause autorun prompt doesn't do anything

[granite mesa]

rewind what are you trying to do in your own words

[worldly harbor]

depends

for me I could do that perfectly fine

[stoic knoll]

i'm trying to run files that should be JARs but dont run

[granite mesa]

try again

[worldly harbor]

could you send the path to the folder it is in? (For if double-click doesn't work)

[stoic knoll]

wait one secomnd

OK so it gives me the command to select java to run it but it says its not an executable file

The file '/home/computeration/Downloads/RusherHackInstaller.jar' is not marked as executable. If this was downloaded or copied from an untrusted source, it may be dangerous to run. For more details, read about the executable bit.

which is ridiculous because it worked perfectly fine before

[worldly harbor]

on the terminal, do "java -jar /home/computeration/Downloads/RusherHackInstaller.jar" also why rusherhack lol

[granite mesa]

Is the mod even meant to be run as a standalone executable?

or is it intended to be run by the game

[stoic knoll]

it's an installer and than i can put the mod into minecraft

[worldly harbor]

I'm wondering that too, but he didn't reply

[stoic knoll]

hobby

fucking finally

it worked

[worldly harbor]

so yeah you already had java but needed to learn how to run jar files without gui

[stoic knoll]

yeah sorry i'm an absolute noobie LOL

[granite mesa]

to run a jar file one does java -jar /path/to/jar

[worldly harbor]

dw bro, I've also had my phase, if you continue using Linux you'll probs love the terminal sooner than later

[stoic knoll]

yeah

[worldly harbor]

nah bro, I swear it was available through GUI

[stoic knoll]

if i didnt play cod or rainbow i probably would have it on my main PC too lol

[worldly harbor]

that or the file managers I use had that option, idk

[granite mesa]

@worldly harbor your environment can be configured to handle jars by calling java its not a function of your filesystem or your file manager its purely a configuration detail

and its unlikely to be configured by default because why would it be

[worldly harbor]

then it may have been pre-configured for that

[worldly harbor]

idk, luck?

[granite mesa]

@stoic knoll I'm suprised that wherever you got that jar file didn't give any instructions whatsoever as far as running it

lol are you pirating it?

[worldly harbor]

I was thinking of that too, but maybe they just skipped it or something?

[worldly harbor]

considering "RusherHack", idk what to think

[stoic knoll]

no i'm not that stupid

i know exactly what 2 do with it i've used it for over a year, its just cuz im on an entirely new operating system i have no clue what to do and if the same rules still apply

[granite mesa]

good so java -jar /path/to/jar did that run ok for you?

[stoic knoll]

yeah

[worldly harbor]

prog languages are more often than not cross-platform, so other than the package names, the commands usually (if not always) are the same

the OS has really nothing to do, other than maybe MacOS, and Linux only the install process

[stoic knoll]

yeah i've never coded a day in my life although i plan to get used to linux because if i have 2 start paying for windows 10 than im getting linux mint

[worldly harbor]

I'm just barely starting myself tbf, other than that the most I'd ever do is compile

[mortal garnet]

Lets continue discussions unrelated to the thread in general channels, so others have a easier time finding helpful thing here.

[worldly harbor]

it's technically very related to the issue but ok...

[granite mesa]

Here is what support for jars would look like in the format of a desktop file in ~/.local/share/applications
