Forge Startup issue with a core or library.


Recommended Posts

I just need a simple "what mod is causing this" explanation:

I've looked up this issue, but this issue is very confusing, as none of the ones i've seen match my issue. Yes i've attached the latest.log, and a mod list.

Seems as though something is wrong with the jar:

[15:14:12] [main/ERROR] [FML]: Contained Dep is not in the jar: mp3spi1.9.5.jar
[15:14:12] [main/ERROR] [LaunchWrapper]: Unable to launch


Here is the problem jar (not sure why it causes this startup issue): mp3spi1.9.5.jar (Allows java to use mp3 files.)

BTW, this issue isn't technically a crash, but the game doesn't say its a crash, it just displays the launcher log text. But it never said "The Game has crashed".

If you know what mod uses this library, please tell me so I can remove it..

Most of the time it doesn't take a programmer to understand crash reports.


Caused by: java.lang.IllegalStateException: Invalid contained dep, Missing from jar: mp3spi1.9.5.jar


Remove that jar or fix its dependencies.

Here something I found out. Modpack still doesn't work, but this core or library was that issue before:


requests "mp3spi1.9.5.jar" which is a faulty library so I removed whatever mod uses "lda-0.1.5-corePlugin.jar". Now, with a folder named "Ding 2" and the game starts, but a new world created never loads.


At this point I think since I can't get any real help because the mods I choose are barely supported I guess I will just never use modpacks again...? Anyway, I think it has something to do with incompatible mods or the launcher I'm using from curseforge selects betas and alpha mod versions. I will keep trying to get the mods working again. I've noticed that my Java version no longer supports really old versions of minecraft either, so I'm kinda use to mods crashing a lot. I used to have a Java 6 computer and it was terrible...

Since my problems are probably worthless and maybe I should stop being blind or stupid to these things, I think I'll do more research on how the heck this stuff works anyways so I won't be so troublesome. Sorry for wasting your time. ?

Spaces should be fine, it's the ! that is used by java to denote files inside of archives. Which is what we're working with. Soo it was looking for a archive named "Ding" with files inside it.

Removing the ! *should* fix it, if not then its most likely a poorly made mod.


Either way we'd need the log to know.

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.
