So I've tried almost everything but when I click on the jar file it opens the archive manager. There is no option to run it with java.

  • Just a hint... java -jar "path to jar" + search for linux desktop shortcut...this way you will learn more, then if someone serves it to you on silver plate :) – RiddleMeThis Jun 13 '15 at 14:14
  • @MichalHagara I know how to launch it from the terminal. Is there a way to launch it from just double clicking it? – Darkar2045 Jun 13 '15 at 14:16
  • you can make it open in java, right click-open with ...search for java sdk or whatever java you have installed....or create desktop entry with Exec=java -jar 'path to jar' or use bash script – RiddleMeThis Jun 13 '15 at 14:25
  • @MichalHagara It won't let me use java runtime from the open with menu – Darkar2045 Jun 13 '15 at 14:29
  • In this case you should be able to use custom command...right click...open with...custom command...'java -jar' withou quotation marks...it should work – RiddleMeThis Jun 13 '15 at 14:35
  • @MichalHagara Where's that? I only see open with application. – Darkar2045 Jun 13 '15 at 14:38
  • click on open with other application... it looks like this in my case http://tinypic.com/r/2mextau/8 – RiddleMeThis Jun 13 '15 at 14:42
  • @MichalHagara I did select open with other application. And I can't view your picture. – Darkar2045 Jun 13 '15 at 14:43
  • I am using Ubuntu Mate, but I suppose that another flavours has this function as well – RiddleMeThis Jun 13 '15 at 14:44
  • @MichalHagara I am using ubuntu – Darkar2045 Jun 13 '15 at 14:44
  • please post picture of what you get when you click: open with other application... my image again: http://i.imgur.com/bbal1Ub.png?1 – RiddleMeThis Jun 13 '15 at 14:44
  • Nautilus doeasn't have this function by default from what I have understood http://askubuntu.com/questions/431703/how-to-add-open-with-custom-command-option-in-right-click-menu-of-nautilus, but it can be added – RiddleMeThis Jun 13 '15 at 14:50
  • Or ubuntu tweak should be capable of file asociating http://popularubuntuquestions.com/add-custom-command-in-the-open-with-dialog/ other solutions are there as well – RiddleMeThis Jun 13 '15 at 15:07

Running jars in linux is easy. Just open a terminal and type java -jar <path to jarfile> then hit enter and voilà it works.

I don't know why you tried to click on it, the location of the .jar file should be in the $PATH of minecraft. I don't have any experience mindcrafting, I have alot of experience programming in Java and administering Java dependant applications on Ubuntu; I also set my brother up with Gary's mod on Ubuntu 12.04.

So basically here's the diagnostic flowchart you want to follow when you are foo-bar:

1) Do you have a java virtual machine (JVM) installed (I used Oracle jdk7u26 I believe on that mod)? You can check by running the following command from command line:

:~$ java -version

2) Is the $PATH to the jre set ($JRE_HOME), either in your local startup script, the global startup script /etc/profile, or did your update the alternatives to give a symlink to /usr/bin/java, /usr/bin/jar? You can check by running the following commands:

:~$ echo $JRE_HOME

:~$ echo $JAVA_HOME

3) Is the location of the .jar in the $PATH of the mincraft executable? In the possibility your using a mod.

4) Whats the permissions of the .jar file you want to run?

:~$ stat thisminecraft.jar

Also you have symlink for the jar and for java cause you updated /etc/alternatives, you can create a bash script, and add the script to a docking application like cairo-dock:

#! /bin/bash

RNJAR="java -jar /home/youruser/MyBin/theminecraft.jar"

$RNJAR

exit

So create a directory like:

:~$ mkdir -p -m0755 $HOME/MyBin

Then copy the script above into gedit and save as 

/home/youruser/MyBin/minecraft.sh

Change the mode of access to executable

:~$ chmod +x $HOME/MyBin/minecraft.sh

And you can create a custom launcher on cairo-dock or even put the script in the $HOME/Desktop (<- I never do this) folder as opposed to $HOME/MyBin.

Good Luck, and may the minecrafting be prosperous.

Java applications can have their own desktop or launcher icon to start like any other application.

To get there we just need to create a minecraft.desktop file in ~/.local/share/applications/ with the following content:

[Desktop Entry]
Encoding=UTF-8
Value=1.0
Type=Application
Name=MineCraft
GenericName=Minecraft
Comment=Start Minecraft
Icon=/home/<user>/.icons/minecraft.png ## choose any Icon you like
Exec=java -jar /full/path/to/minecraft.jar
Categories=Games
Path=/home/<user>/.minecraft/

Create or download any icon you like it to display and store it in ~/.icons. The desktop file needs to have executable permission (right click Properties, Permissions, tick Allow executing file as program).
