Hello,

 

I've been having trouble running my Minecraft Forge mod through my IDE (Netbeans). I'm getting this error that it can't find the lwjgl library, and it's closing down because of this. I've searched the error up and read every solution, but nothing seems to work. D:

 

I tried putting this argument in the JVM section of Project Properties -> Manage Built-In Tasks -> Run:

 

-Djava.library.path="Volumes\Roberts HD\Robert\Library\Application Support\minecraft\bin\natives"

 

That should direct the java.library.path to the location with the lwjgl jars, right? Is there anything to be done? Thanks. Keep in mind this only happens when attempting to run the mod inside the IDE.

Um... there is no natives folder in my forge directory. ;_;

Uh...

 

I'm confused, lol.

 

Do you mean build/natives as a directory, or build/natives as "build or natives?"

build/natives as in

|
|__build
   |__natives

I'm still confused. D: Please go easy on me.

 

There is no "natives" folder in my forge directory whatsoever.

...

Go into your forge directory (where your build.gradle is).

Open the build folder.

Then open the natives folder. THAT FOLDER is where the natives are and where you need to point your IDE.

 

...

 

You don't seem to understand. There is no "natives" folder.

 

 

 

 

._.

Did you run setupDecompWorkspace?

 

Yes, I did. That's where I got all those folders from. Apart from the ability to run things, it all works fine.

Try running gradlew runClient. That should definitely set up the natives if it hasn't already.

If that doesn't work try starting from scratch. This all looks pretty weird to me and shouldn't happen.

 

I tried it, and this is what I got:

 

iMac-5:forge Robert$ ./gradlew runClient

BUILD SUCCESSFUL

Very weird. Try setting up everything fresh.

 

Okay, so I downloaded a new version of Forge. I did cd <forge directory>, and then ./gradlew setupDecompWorkspace. After it was done building, I looked in build, and saw there was a natives directory (yay!). After launching NetBeans, opening the Forge grade project (using the Gradle plugin) and copying my packages over to the new project, I configured the command args for "Run", setting them to "runClient." I clicked "Run," and it launched!

 

But it was too good to be true. I closed it, did "Build and Clean," then "Run." To my surprise, I got the familiar error about libraries. I checked back in the build directory, and (gasp), the natives folder had vanished! So question: Is Build and Clean the culprit?

I have no clue about NetBeans, sorry.

 

Okay. ;-; Thanks anyhow.
