¿How can I add an external jar?

[ElOsito123]

Hi, I'm trying to add an external jar to eclipse and everything works perfect, but when I put the mod in minecraft it says that it does not find the class of the jar that it exports, and look for how to do it, I saw that many say that it uses "shading" but already I did it and it does not work or I do not know if I do something wrong, I am new to this and I know it is wrong and it is not recommended but I would like someone to help me on how to do this and if it is possible to give me examples, I only have a problem with this and thanks.

[ElOsito123]

Can you give me an example please? It's the first time I do this,

by the way the jar is not another mod, it's just another jar that I need.

I do not know if I did it well but I tried to do with "Shadow" and in MC I get this error:
 

The game crashed whilst there was a severe problem during mod loading that has caused the game to fail
The game crashed whilst there was a severe problem during mod loading that has caused the game to fail
Error: net.minecraftforge.fml.common.LoaderException: java.lang.NoClassDefFoundError: club/minnced/discord/rpc/DiscordEventHandlers$OnReady

It is not a random jar, it is the external jar that I want to use

By "random" I think he means that it is not specified as a dependency, so from the point of view of including it is is unrelated to your dependencies and thus "random".

[ElOsito123]

I've never used it, try to do it, the jar I'm using offers an "extension" to gradle https://github.com/MinnDevelopment/java-discord-rpc, but I do not understand how to use it

[ElOsito123]

and the jar as I import it to eclipse? or use I do it from the location I want?

[ElOsito123]

I just need this, I do not know what I'm doing wrong, I did what it says I need to do

and this error appears:

The game crashed whilst there was a severe problem during mod loading that has caused the game to fail

I still need to use shadow ?, in github it says that it adds this to gradle and to build it I only execute in the console "gradlew build" but it generates me 4 .jar files

I'm reading everything he told me, but I had one more question, this person did something similar to what I'm looking for but I do not implement anything to his gradle: https://github.com/knuieiey/MeowRPC/blob/master/build.gradle

[ElOsito123]

Well I did this and I get the same problem, what am I doing wrong?

https://pastebin.com/Nwe84ca4

[ElOsito123]

I did this but I still have the error

 

shadowJar {
   relocate 'club.minnced.discord.rpc', 'me.test.MegaMod' <- Main class
}

To build, I think you mean this: I use a console, I type the command "gradlew build" and when it finishes I go to the "build \ libs" folder and place the mod in the mods folder of mc

[ElOsito123]

@diesieben07 I'm fine in this?: 

 

jar {
   manifest {
       attributes 'Class-Path': '/libs/java-discord-rpc-2.0.1-all.jar'
   }
}

 

or should I be like this?:

 

jar {
   manifest {
       attributes 'Class-Path': 'com.github.MinnDevelopment:Java-DiscordRPC:v2.0.1'
   }
}

Ninguno es necesario.

 

Bueno, necesitas usar la tarea shadowJar si quieres construir un jar con las bibliotecas sombreadas. ¿Leíste la documentación de Gradle Shadow?

I'm using that, which is what he told me but I still have the same mistake, what am I doing wrong? By the way, I have to do the class or just create it? my class is "me.test.test" then it would be "me.test.test.repackage.club.minnced.discord.rpc"?

This is my gradle: https://pastebin.com/Hybj96Mn

I need 1.8.9, then it is impossible to do it?

[ElOsito123]

But why does not it work for me? I do not ask you to kill yourself helping me, but I've seen others use 1.8.9 and this works for them, why do not I do something wrong? Do I need another version of something? (other than MC, I want to work on that version)

[ElOsito123]

so just download forge (1.8.9) use the 2 commands to extract and make the eclipse project and I had some problems but solve them, in fact everything works perfectly, I can make a mod and it works, what does not work is this to export the jar

[ElOsito123]

So is there any way to rebuild it?

[DaemonUmbra]

To be honest this is the issue I'm seeing here, this is not directed solely at you, but you are the most recent case.

 

1.7.10 and 1.8.9 are old versions and should not be used for active development, your excuse that "I've seen others use 1.8.9" is the core of a cycle that keeps these ancient versions in a zombie-like state. People see others developing for these versions and assume that they are still valid versions to use, resulting in users ignoring recent versions in favor of using old versions that may be lacking features and/or security improvements that come from later versions.

 

Imagine you had developed a game and after discovering and fixing a horrendous security issue in your game you then learned that people playing your game refused to update past the version just prior to the fix, then complained about the bug while insisting you continue to support that version of the game.

 

As long as people continue to use the excuse of "They are doing it so it must be ok" old versions and the bugs in them will continue to haunt users of those versions as well as those they demand assistance from.

[ElOsito123]

But for what I want to use that version is because I use that version, I understand that you do not like my thought, that you want me to update, but I do not like the superior versions of mc, I like this and well I do not "shield" that someone else has done it if not because they are giving me to understand that it is "impossible" but someone else has already done it, this is not a tantrum that I want this, it is that I would like it and I know it can be because there are mods for those versions, I do not want to update for the simple reason that I do not want, I think it's my choice and even if you do not like it, it should not matter, I'm really just looking for help with this, if someone does it is because you can.... At least I think so.

[DaemonUmbra]

You need to do more research on Shadow, you are using the wrong plugin id and, if you are using the same gradle version I am (2.14, which the MDK has been shipping with for a while now), you are requesting the wrong version of Shadow.

[ElOsito123]

I kept trying, but it's still the same

The only reason people use 1.8.9 is because all major servers use 1.7 or 1.8 due to the PVP part of the game. Until Mojang rolls back 1.9 changes, people trying to code 1.8 won't stop coming =/

They won't. You want it back the way it was? MOD IT.

Oh wait, someone already did.
