What do you need help with?

I wanna use baritone on MultiMC, so I created this custom Patch:

{
"+tweakers": [
"baritone.launch.BaritoneTweaker"
],
"formatVersion": 1,
"libraries": [
{
"name": "net.minecraft:launchwrapper:1.12"
},
{
"name": "baritone-api:1.5.2",
"M1.15.2-hint": "local",
"M1.15.2-filename": "baritone-api-1.5.2.jar"
},
{
"name": "com.github.ImpactDevelopment:SimpleTweaker:1.2",
"url": "https://impactdevelopment.github.io/maven/"
},
{
"name": "org.spongepowered:mixin:0.7.11-SNAPSHOT",
"url": "https://repo.spongepowered.org/maven/"
},
{
"name": "org.ow2.asm:asm-all:5.0.3",
"url": "https://repo1.maven.org/maven2/"
}
],
"mainClass": "net.minecraft.launchwrapper.Launch",
"releaseTime": "2019-07-23T20:50:21+00:00",
"type": "release",
"name": "Baritone",
"uid": "baritone",
"version": "1.5.2",
"requires": [
{
"equals": "1.15.2",
"uid": "net.minecraft"
}
]
}

Sadly MC crashes with this error:

[main/INFO]: Loading tweak class name baritone.launch.BaritoneTweaker

Any suggestions, how i can fix this?

Final checklist

• I know how to properly use check boxes
• I have not used any OwO's or UwU's in this issue.

You're missing the baritone library, your json is probably incorrect.

what library?

the error is literally you don't have baritone

do i have to put baritone api in a specific folder inside of libraries?

No, the json does it for you. Your json is incorrect.

i want to make it different, cause the impact maven repo is sieriously outdated, so i downloaded the newest api version for my client and put it into the libraries folder.
do they have some kinda patch installed into the api?

no clue, sorry

oh :(
could you maybe tell the impact devs, to keep their maven repo always up to date?

ye, just did so now

ty so much
