Load / Inject JAR file at runtime


CraftedCart

Recommended Posts

Hi there.

The mod I'm working on requires another jar file to function properly (slick-util.jar). I have it set up so that if the file

mods/CraftedCart/slick-util.jar

doesn't exist, my mod will download it before doing anything else (in pre-init). The only issue I have now is how do I load the .jar file. I am aware of the Loader and ModDiscoverer classes, however I have no idea how to use them, or if they will help.

 

(Oh, and slick-util.jar isn't a mod, but it works if I throw it into the mods folder)

 

EDIT:

Nevermind, found it whilst looking through CodeChickenCore

 

File depsPath = new File(Minecraft.getMinecraft().mcDataDir.getAbsolutePath(), "mods/CraftedCart");

LaunchClassLoader loader = (LaunchClassLoader) DependencyUtils.class.getClassLoader();
loader.addURL(new File(depsPath, "slick-util.jar").toURI().toURL());

 

As far as I can tell, my DependencyUtils class can be replaced with another one of your own classes.

The example above will load mods/CraftedCart/slick-util.jar

You should read about Shading.

 

That's really cool.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.
