¿How can I add an external jar?

Recommended Posts

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.

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

 

This is my build.gradle: https://pastebin.com/WuZxWtYh

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

{https://pastebin.com/vj1C7qh7}

and this error appears:

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

@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

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)

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.

This is my Forum Signature, I am currently attempting to transform it into a small guide for fixing easier issues using spoiler blocks to keep things tidy.

 

As the most common issue I feel I should put this outside the main bulk:

The only official source for Forge is https://files.minecraftforge.net, and the only site I trust for getting mods is CurseForge.

If you use any site other than these, please take a look at the StopModReposts project and install their browser extension, I would also advise running a virus scan.

 

For players asking for assistance with Forge please expand the spoiler below and read the appropriate section(s) in its/their entirety.

Spoiler

Logs (Most issues require logs to diagnose):

Spoiler

Please post logs using one of the following sites (Thank you Lumber Wizard for the list):

https://gist.github.com/100MB Requires member (Free)

https://pastebin.com/: 512KB as guest, 10MB as Pro ($$$)

https://hastebin.com/: 400KB

Do NOT use sites like Mediafire, Dropbox, OneDrive, Google Drive, or a site that has a countdown before offering downloads.

 

What to provide:

...for Crashes and Runtime issues:

Minecraft 1.14.4 and newer:

Post debug.log

Older versions:

Please update...

 

...for Installer Issues:

Post your installer log, found in the same place you ran the installer

This log will be called either installer.log or named the same as the installer but with .log on the end

Note for Windows users:

Windows hides file extensions by default so the installer may appear without the .jar extension then when the .log is added the log will appear with the .jar extension

 

Where to get it:

Mojang Launcher: When using the Mojang launcher debug.log is found in .minecraft\logs.

 

Curse/Overwolf: If you are using the Curse Launcher, their configurations break Forge's log settings, fortunately there is an easier workaround than I originally thought, this works even with Curse's installation of the Minecraft launcher as long as it is not launched THROUGH Twitch:

Spoiler
  1. Make sure you have the correct version of Forge installed (some packs are heavily dependent on one specific build of Forge)
  2. Make a launcher profile targeting this version of Forge.
  3. Set the launcher profile's GameDir property to the pack's instance folder (not the instances folder, the folder that has the pack's name on it).
  4. Now launch the pack through that profile and follow the "Mojang Launcher" instructions above.

or alternately, 

 

Fallback ("No logs are generated"):

If you don't see logs generated in the usual place, provide the launcher_log.txt from .minecraft

 

Server Not Starting:

Spoiler

If your server does not start or a command window appears and immediately goes away, run the jar manually and provide the output.

 

Reporting Illegal/Inappropriate Adfocus Ads:

Spoiler

Get a screenshot of the URL bar or copy/paste the whole URL into a thread on the General Discussion board with a description of the Ad.

Lex will need the Ad ID contained in that URL to report it to Adfocus' support team.

 

Posting your mod as a GitHub Repo:

Spoiler

When you have an issue with your mod the most helpful thing you can do when asking for help is to provide your code to those helping you. The most convenient way to do this is via GitHub or another source control hub.

When setting up a GitHub Repo it might seem easy to just upload everything, however this method has the potential for mistakes that could lead to trouble later on, it is recommended to use a Git client or to get comfortable with the Git command line. The following instructions will use the Git Command Line and as such they assume you already have it installed and that you have created a repository.

 

  1. Open a command prompt (CMD, Powershell, Terminal, etc).
  2. Navigate to the folder you extracted Forge’s MDK to (the one that had all the licenses in).
  3. Run the following commands:
    1. git init
    2. git remote add origin [Your Repository's URL]
      • In the case of GitHub it should look like: https://GitHub.com/[Your Username]/[Repo Name].git
    3. git fetch
    4. git checkout --track origin/master
    5. git stage *
    6. git commit -m "[Your commit message]"
    7. git push
  4. Navigate to GitHub and you should now see most of the files.
    • note that it is intentional that some are not synced with GitHub and this is done with the (hidden) .gitignore file that Forge’s MDK has provided (hence the strictness on which folder git init is run from)
  5. Now you can share your GitHub link with those who you are asking for help.

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.

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.

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.

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.

    • There's a scheme I got into where they promised to trade Bitcoin for me and take a cut as a commission. Seemed like a good idea at the time. But then, things went south real fast. They ended up transferring   $190,000 worth of my Bitcoin. I was devastated and felt completely helpless. That's when I stumbled upon the Wizard Web Recovery Tool. It was like a beacon of hope amid chaos. With this tool, I could finally start digging into what went wrong and hopefully get my Bitcoin back. Using Wizard Web was surprisingly easy. I just had to plug in some details about my Bitcoin account and let it do its thing. It started scanning the internet, looking for any clues about what happened to my Bitcoin. It felt like having a detective on my side, searching for answers. And guess what? Wizard Web found some leads. It uncovered evidence of the scheme's shady dealings and helped me track down the people responsible for losing my Bitcoin. Armed with this information, I took the case to court. After a long and hard-fought legal battle, the court ruled in my favor. The perpetrators were held accountable for their actions and faced criminal charges for their involvement in the scheme. It was a victory not just for me, but for anyone who's been taken advantage of by these kinds of scams. Thanks to Wizard Web Recovery, I was able to get justice and reclaim what was rightfully mine. It showed me that even in the face of adversity, there's always a way to fight back. And with the right tools and determination, anything is possible.   The following is the contact information for Wizard Web Recovery.   Email: wizard web recovery((@))programmer . net
    • Hello, good morning. I know some programming and I'm interested in mod creation. That's why I've decided to follow a tutorial guide on YouTube by TurtyWurty. https://www.youtube.com/watch?v=DhoX9cmAZqA&t=160s&ab_channel=TurtyWurty I've followed the tutorial perfectly. The problem is that when checking the food, the texture doesn't load for me. However, everything seems fine no matter how much I check. I'm sure it's something trivial, the problem is that I can't find it. Could you help me solve it, please? I leave a zip of my file so you can edit it freely. forge-1.20-Civicraft.rar
    • If you have nvidia graphics, it's important that you make sure Minecraft (and anything Minecraft-related) is set to prefer high performance graphics first. If you only update your AMD drivers it might fix the issue but cause severe performance loss vs Vanilla as it'll be running on the integrated graphics instead of dedicated nvidia graphics
