[1.14] Help setting up forge development environment

What...? I don't know where you got these instructions from, but they are wrong.

1. Clone the repo.
2. Open build.gradle in IntelliJ (i.e. import the gradle project).
3. Run the setup gradle task.
4. Refresh the gradle project in IntelliJ.

Done.

 

 

I followed these steps, which I found elsewhere on this forum. I am able to make changes, run forge client, and see those changes. I am using IntelliJ IDEA Community 2019.2.4

 

However, I'm not able to "test with existing mods" as described in the docs for 1.13.x (which I think are the latest docs at the time of this writing).

 

The general idea from the docs and linked video is:

1. import another mod as a module in the project settings

2. add forge main as a module dependency in the new module

3. add the output path of the new module as a "JAR or Directory" runtime dependency in forge main

 

I have tried adding a mod of my own that works, as well as the example mod that comes with the forge mdk. In either case, forge client runs, the minecraft client starts. When I click the mods button from the minecraft title screen, I see only "Minecraft" and "Forge" in the list of mods. (which is troubling because I think I also expect FML).

 

There is an error in the output of running forge client: `Incompatible Java and native library versions detected.` That seems pretty significant, but I'm not sure 

 

Here is the output of running forge client:

I noticed that in the dependencies list for forge main there are two entries for LWJGL:

 

Gradle: org.lwjgl:lwjgl:3.2.1

Gradle: org.lwjgl:lwjgl:3.2.2

 

I'm not sure how to follow the suggested actions a) and b) in the above output.

 

I'd really appreciate some guidance! I am adding events to hook into grass spreading, and the change itself is really straightforward. I feel like I could have a PR up soon, but I am not interested in pushing untested code.

 

Thanks!
