Minecraft Java Edition 1.12 2 Download
Elfreda Dasovich
Have you tried setting system default Java to be Java 8? I recently tried using Forge 1.12.2 and it would crash instantly when you tried to start it from the launcher. Try running sudo update-alternatives --config java and type the number of Java 8 to set as default, then try starting Forge again. That fixed the problem for me, as Forge versions 1.12.2 are only compatible with Java 8.
There are some excellent Minecraft Java Edition mods such as Serene Seasons and Dynamic Trees which provide motivation to run Minecraft Java Edition 1.12.2.Minecraft Bedrock users will find it's well worth buying a new set of Minecraft licenses for Java Edition,in order to experience amazing mods like Ice and Fire and the great variety of choices.
For those that don't know, this only applies to Minecraft Java Edition.Minecraft Bedrock is not mod-able, and to mod Minecraft Java Edition the great Minecraft Forge is also needed.If you only have Minecraft Bedrock, now is the time to re-purchase all your licenses for Java Edition. It's worth it.
Although I'm not sure about the particular errors that the OP reports, I ran into a couple of similar-looking Java errors when trying to install Minecraft Java Edition 1.12.2.I found using Java 8 from scratch for all steps worked with Mac OSX Minecraft server and Ubuntu 20.04 and Windows 10 clients.
For Minecraft Forge 1.12.2, when installing Minecraft server, Minecraft client, and Forge, Java 8 needs to be the system default Java.Multiple Java versions can be run reliably and simultaneously.It's probably easier to run simultaneous versions than uninstalling existing (probably later) Java, which might break something if that's done, anyway.
Also, Minecraft Java Edition needs to be installed first, and run at least once, before attempting the install of Forge, for server and clients.The Forge installer jar needs to be used, not the "universal" jar.
You will need to be able to follow along with CLI bash commands, use sudo when necessary, and understand some basics about your user home directory and Minecraft install directory for your OS.There's plenty of support on-line if you need to search these aspects up.It may be helpful to reboot the machine after some steps; try it if the process seems blocked.
If there are still problems reaching Java 8 it may help to set the JAVA_HOME environment variable.The canonical path to the current Java can be determined using readlink.Previously it may have returned something like this:
Chop off the /jre/bin/java or /bin/java segment to determine the Java home directory.Set that path as the JAVA_HOME environment variable in the shell profile of the user that will be running Minecraft:
Contrary to some guides, the JAVA_HOME variable does not reference the bin directory.But the bin directory should be referenced in the PATH variable, which could also be added if problems are still happening:
After installing Java 8, unless there were no other Javas present before, it will still probably not be the system default.To check which version is being used call Java with the version option in a fresh terminal:
Now the JAVA_HOME environment variable needs to be set to the path listed for Java 8 (Java 1.8).Specify this in the bashrc / bash_profile / profile or Zsh profile for the user that is running the server,so that it is set every time the user logs in / starts up.The java_home command can help with this:
The official Minecraft server JAR for 1.12.2 is available here: -us/article/minecraft-1122-releasedDownloading from the link on that page should provide minecraft_server.1.12.2.jar.Run the JAR file to install it, using the newly installed Java 8:
Remember, it will be necessary to run the Minecraft JAR twice.The first time it will generate some files and then drop out because the EULA is not signed.Edit eula.txt to read eula=true and then re-run to make sure Minecraft Java Edition server runs.
There are two executables involved in running Minecraft as a client: the Launcher and the game.This is important because the game needs to be installed before Forge is installed, and only playing the game will trigger download and install of that version of the game from the Launcher.
The official Minecraft Launcher is available here: -us/downloadThe page has links for a Mac DMG installer, and a Windows MSI installer.Of course, it can also be downloaded directly from the command line on Linux:
When downloading the game in the Launcher be patient.Microsoft is only a small company with few resources and it may take some time, and even one or more re-tries, to download the game from their server.It may also be necessary to re-boot afterwards.
When Minecraft Launcher is first installed there are no Minecraft games available on the system.I found that playing latest Minecraft single player was a necessary step in order to unlock the previous versions in the Minecraft Launcher Installations.So play Minecraft single player!
Again, on Linux, Mac and Windows the same process should be possible.After playing latest Minecraft from the Launcher, apart from installing the latest Minecraft client, the Launcher should now offer previous versions of the Minecraft game client.
At this point old-fashioned vanilla Minecraft Java Edition 1.12.2 is available as game clients and server.I guess it's worth checking this works by attempting a 1.12.2 vanilla network game to the server.
This operation is not totally trivial. Avoid all links after redirect, and wait for the "skip" button to appear top-right.I won't detail click-by-click instructions here, but they are available: -minecraft-forge-windows-mac/
For Minecraft server it should now be possible to run the new Forge JAR.This is the short script I use to start our family Minecraft Forge on Mac OS,setting the environment variables as well, as a precaution:
Minecraft is a fun game to play with friends, and modding the game can add many more possibilities. Server hosting websites or Minecraft Realms cost a monthly subscription to use. If you don't have the money to have a separate website host the server for you, setting up your own server for free will be your best option. Here's how to setup a modded Minecraft server in 1.12.2 (works with most past and future updates, you can find the specific .jar file for whatever version you're hosting).
It'll download MinecraftInstaller.msi, launch it and follow the instructions to install it. Once installed, you will want to launch vanilla 1.12.2 at least once in order to install all the important stuff. Under the Installations tab, click + New, then under Versions, select 1.12.2. Select 1.12.2 from the drop down menu, and press PLAY. Once it fully loads to the menu screen, exit the game.
In order to start hosting a server, you need these files. Reopen the Forge installer and select Install Server, and the location you want it to be installed.
Now that its been installed, double click on forge-1.12.2-14.23.5.2838-universal.jar to launch it. once you do that, the folders logs, mods, and eula.txt will appear in the folder.
Double click on the eula.txt to open it, and change the false to true. ctrl+s or click File then Save, then close the txt. Once that's done, relaunch the .jar. You'll see a bunch more files appear in the Server folder, and a window open up titled Minecraft server. Congrats! You now have a local modded Minecraft server! But we're not here for that, we're trying to create a server that anyone can connect to. Close the Minecraft server window.
Once you download the mods' .jar file, make a copy of it. Open your server's mods folder and paste the mods there. Then you'll want to move the original mods you copied to your .minecraft folder. to find it, press the windows key and type %appdata% into the search box. Once there, click on .minecraft. In there should be a folder labeled mods. If there isn't, make one. Put all of the same mod files into the mods folder.
Before you even launch the server again, there is a way to majorly reduce the lag on the server and your computer. Right click in the Server folder and create a new text document. Title it Server Launcher. Open it, and copy and paste the following text:
Once the text has been pasted into the text file, select File, then Save As. Change the Save as Type to All Files, and rename the file from Server Launcher.txt to Server Launcher.bat. Now double click on the .bat file every time you want to start the server. Launch the server, let it fully load, then close it.
The server now works locally! Anyone on the same IP as yours can now join the server. In order to allow people not on the same IP to connect,you'll need to port forward your server. To do this, google Whats my IP? on Google. Take the number it gives you, copy it, and paste it into the address bar. This will most likely take you to your router's website where you can manage your router's settings. Enter the password to your router to continue. My router is a Linksys, you'll want to google around to find the steps with your specific router. You'll want to find the Port Range Forwarding section of your router, and enter in the following information.
In order to get your computer's IP, hold down the windows key and press R. In the box that pops up, type cmd. When the command prompt opens up, type ipconfig. Look for the line labeled as IPv4 Address, and copy the IP address there. Type that number in for your Device IP above.
The server should now be up and running! Double click the .bat file to launch the server, start up Minecraft, and enter in your public IP (when you googled "what's my IP") in the multiplayer menu. Connect to the server, and enjoy your new world!
