[SOLVED] How to specify absolute path in mod_list.json?

Recommended Posts

I've placed all my mods in a central location, and I'm trying to load them using a mod_list.json in ".minecraft/mods/1.10.2". I'm not sure how to specify an absolute path, though. I tried doing what the Github page said, and my .json looks like:

 

{
  "repositoryRoot": "absolute:C:/Users/[MY-USERNAME]/Documents/Minecraft/Mods/1.10.2",
  "modRef": [
    //lots of mods here
  ],
  "parentList": ""
}

 

When I start up the game, however, none of the mods load. The launcher logs say:

 

11:21:26 PM FML Failed to read modList json file .

11:21:26 PM FML Failed to find the specified repository root absolute:C:/Users/[MY-USERNAME]/Documents/Minecraft/Mods/1.10.2

11:21:26 PM FML Failed to read modList json file .

11:21:26 PM FML Failed to find the specified repository root absolute:C:/Users/[MY-USERNAME]/Documents/Minecraft/Mods/1.10.2

 

Possibly relevant: I'm using the latest version of the new beta native Minecraft launcher, using the latest version of Forge for 1.10.2, and I'm running Windows 10 64-bit.

 

Do you have to type the absolute path differently? Or is the mod_list.json thing just broken with the new launcher?

The

absolute:

prefix is only used for list file paths, i.e. the

--modListFile

command-line argument and the

"parentList"

property in the list file.

 

The

"repositoryRoot"

property is absolute by default, but you can use

.

for the Minecraft directory or

..

for the parent directory (like regular filesystem paths).

Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.

I've already read that. That's how I knew how to format the mod_list.json in the first place. But thanks anyway. :)

Ok, I changed the mod_list.json, and here is what it looks like, complete with all the mods I have listed:

And now Forge just crashes when I try to start the game. Here's what the launcher logs say:

I'm not sure why it seems to think I'm running Windows 8.1. (Is it just a minor bug with Forge, the new launcher, or what?) Also, in case you're wondering what's up with the .minecraft folder, I actually have a symbolic link in the normal location where the .minecraft folder would be. The symlink links to the actual location of my .minecraft folder, which is in my Dropbox, so I can use the same Minecraft installation on other computers or on my Ubuntu partition. (Also in case my laptop dies, so I don't have to worry about losing my worlds.) I'm not sure if I'm doing something wrong, if it is a bug with Forge, or if it is a problem with the new launcher & Forge. Also, no, my username is not literally [uSERNAME].

Each string in the

"modRef"

array must be a Maven-style locator composed of three or four parts separated by colons (

:

). None of the entries in your mod list use this format.

 

The wiki page explains how these locators are mapped to file paths:

{
  "repositoryRoot": "/a/path/to/a/directory",
  "modRef": [
    "cpw.mods.ironchest:ironchest:1.7.2-6.1.10:universal",
    "appeng:appliedenergistics2:rv1-stable-1"
  ],
  "parentList": "/a/path/to/a/parent/json/of/the/same/format"
}

 

This will attempt to load files "cpw/mods/ironchest/ironchest/1.7.10-6.1.10/ironchest-6.1.10-universal.jar" and "appeng/appliedenergistics2/rv1-stable-1/appliedenergistics2-rv1-stable-1.jar" from under the repository root directory.

I was able to get it working and have a rough idea of how to do it now, but I still don't quite understand. (I have no prior experience with Maven.) Should I organize all the mods into folders based off of their actual repository formats or can I make up my own organization? In the example, how does it know that "universal" refers to the "ironchest-6.1.10-universal.jar" file? How exactly does a Maven-style locator work? I'm also curious as to why the mod_list.json uses this format and what the advantages are.

 

Basically, I've got it working, but I don't know why or how it works. :P

Maven coordinates (which the wiki page calls locators) are explained here.

 

The mod list format requires you to specify the groupIdartifactId and version fields, with classifier as an optional extra. The packaging field isn't supported because it's always jar for Minecraft mods.

 

For consistency you should try to use a proper Maven structure, but there's nothing stopping you from making up the groupIds completely.

 

I don't know exactly why the mod list format uses a Maven structure, but it's probably because it's a pre-existing structure that's very popular in the Java community and is used by many mod developers to host their mods in a way that lets other mods can depend on them.

Thanks for the helpful link and explanation, Choonster! I understand the format a whole lot better now. :D
