Obtaining Logs/Crash Reports/ModList on Different Launchers, Server Software, and MC Forge Installer

[amerigovespuccip]

This is a guide explaining how to get logs on various launchers.   If there is a launcher you want to see added reply in the comments.

Once you have logs you can either upload them as an attachment if they are in the form of a file, or if its in clipboard format you can put on a paste website.

 

Vanilla Launcher (Official one provided by Mojang)

Spoiler

Most of the time the logs will be in the minecraft/logs/ folder

Unless set to something else the Minecraft Folder is generally located in these locations:
Windows: %appdata%/.minecraft/

Mac: ~/Library/Application Support/minecraft/

Linux/UNIX: ~/.minecraft/

There should be 2 main files: debug.log and latest.log you want both

debug.log mainly shows up when there is a crash so does not always exist

There are also crash reports in minecraft/crash-reports/ .Crash reports are sometimes included in debug.log but it may be good to add it separately as well. Make sure to check the date on the crash report so its the correct date.

Minecraft Server

Some stuff you may not get from these logs though, such as if the jar fails to start. In this case you should run the sh/bat file to see the error. If you are running a server on a version before 1.17 you want to run the server jar from the command line. To do this you want to do

java -jar <jar-name>

Make sure you have cd'd to the servers folder and replace <jar-name> with the name of the jar you use to run the server.

MinecraftForge Installer
 

Spoiler

New versions of the Minecraft Forge installer should have a button to automatically open the installer logs for you, but if you are on an older version or you did not get this the log file normally generates right next to the jar file, if this is still not the case you can run the installer from the command line and copy it from there by doing

java -jar <jar-name>

Make sure you have cd'd to the servers folder and replace <jar-name> with the name of the jar you use to run the installer

ModLists
 

Spoiler

Go to the folder you normally go to install mods (this is different per launcher but it can often be obtained by going into the game and pressing the mods button on the start screen and pressing Open Mods Folder). When you are in the mods folder open a terminal from there. On Linux Distros or on Windows 11 you can right click and press Open terminal here and it will automatically cd to the mods folder. On other platforms open up the command line and type in

cd <path-to-mods-folder>

(replace <path-to-mods-folder> with the full path to the mods folder which can often be obtained by just dragging the folder in there).

Now once you have a command line cd'd into the mods folder we can create the list. If you are on Windows type in dir and if you are on a Unix-like platform type in ls to get a list of all the files in the mods folder.

Note: We are not officially affiliated with any of the 3rd party launchers, we cannot fix their errors and cannot attest for differences or problems in them and are going from personal experience.

CurseForge Launcher
 

Spoiler

Go to the Instance you want to get logs for. On the right side there should be a sandwich menu right next to the play button consisting of 3 dots stacked on top of each other, click on it and press Open Folder    it should have a folder icon next to it. You can also right click the instance from the instances menu and press Open Folder. Here is a picture of the button (note that it is highlighted, it is normally not yellow)

Most of the time the logs will be in the logs folder

There should be 2 main files: debug.log and latest.log you want both

debug.log mainly shows up when there is a crash so does not always exist

There are also crash reports in crash-reports .Crash reports are sometimes included in debug.log but it may be good to add it separately as well. Make sure to check the date on the crash report so its the correct date.

TLauncher

Spoiler

Note: We will only help you on the forums or Discord if you are authenticated with account type msa (Microsoft)

While TL does offer logs in the logs folder, they are not as detailed and they are GZipped and in different instances they can be in the instance folder.

What you instead want to do is copy from the Developer Console. To enable it  press the settings Icon (the one with the gears on it) and press the 2nd tab (called Launcher Settings), and set Developer Console from None to Global. The console should appear. You can right click the console to copy the log, clear the log, and save the log as a file (recommended for Discord). Make sure you clear the console and run the game again so you only have the logs for the latest run.

MultiMC (and derivatives)

Spoiler

Upon loading the instance, right click the instance and press Edit. If you have started the game during your current session there should be at the top left a button called Minecraft Log which has the Minecraft Log. It can easily be copied, uploaded to a paste site automatically, or cleared. There is also another section called Other Logs which may have more logs in it including debug.log and latest.log and logs from mods.

GDLauncher

Spoiler

GDLauncher comes with a chromium backend making it slow and not work on all platforms but even worse makes the logger and debugger tools chromium based and creates very ugly logs (especially with System.out.println), but it is still possible to get logs.

On the top right corner (or top left on Mac or some linux distros) there is a console button and switch from Elements to Console. You can then copy all lines by selecting one and doing ⌘A or CtrlA and then ⌘C or CtrlC to select all and copy.

Alternatively

You can get logs from the file.

Windows: %APPDATA%\GDLauncher\log.log

Linux/UNIX: ~/.config/GDLauncher/log.log

MacOS: ~/Library/Logs/GDLauncher/log.log

We suggest you read GDLauncher's official guide https://github.com/gorilla-devs/GDLauncher/wiki/Console-and-Log
