[General] Trouble setting up dev environment for IntelliJ in Linux

[Cerandior]

Okay so getting some specific details out first:

Linux OS: Manjaro 19.0.1 XFCE

Java Version: openjdk version "1.8.0_242"

Gradle Version: Gradle 6.1.1

So what is the problem? Well, I have my dev environment already set up on Windows. I just recently installed Manjaro on dual boot with Windows on my machine as I needed Linux for some other (uni) projects of mine. I like to delve into minecraft modding from time to time as a fun way of practicing my (newly acquired) java knowledge. Because I am spending a lot of time in Linux at the moment because of the other projects, I decided to set up the dev environment here as well so I don't have to keep switching between Windows and Linux just to do some minecraft modding.

I thought it wouldn't take me long. Just cloned my github repo into some folder, imported the project in intellij through the build.gradle file and so far so good. Now at this point in Windows, you just run gradlew genIntellijRuns in the intellij terminal (you can probably use powershell too) and you are ready to go. In Linux, I wasn't able to do that because the gradlew command was not being recognized. I tried running that through the System's terminal as well and gave me the same error.

I also tried to run the command with the gradlew file that is present in the project directory like this: ./gradlew genIntellijRuns however that gave me another error:

Error: Could not find or load main class org.gradle.wrapper.GradleWrapperMain

 

So I did some "research" online, and apparently you have to build the gradle wrapper? I really don't know what gradle is, or what the gradle wrapper is because I have never had any experience with it outside minecraft modding. Even here, although it might be an essential part of the project, it is barely touched on by the developer apart from building the project so I never felt the need to look for more information related to it.

Anyway, I installed gradle on my Linux, headed over to the terminal again, navigated to my project folder and ran gradle wrapper to build the wrapper. This initially seemed to work, however it didn't. It ended up giving me this error:

New Dep: net.minecraftforge:forge:1.14.4-28.1.96_mapped_snapshot_20190719-1.14.3

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring root project 'vanilla-extended'.
> Failed to notify project evaluation listener.
   > org.gradle.internal.nativeintegration.services.FileSystems.getDefault()Lorg/gradle/internal/nativeplatform/filesystem/FileSystem;

 

 

 

So I am assuming, I can't build the wrapper with my installed gradle version because the forge gradle version is seemingly older? Do I have to find another version for gradle now, or is there something I can modify inside build.gradle that can fix this problem?

Thank you in advance.

There is a reason the MDK comes with a gradle wrapper configured for a specific version.

Please use it.

You do not need to "build" it, you just have to use it. If you do not know what it is, reading the documentation usually helps:

https://docs.gradle.org/current/userguide/gradle_wrapper.html.

Ok, so I managed to generate the runs by downloading version 4.10 of gradle. Running gradle wrapper command at the folder of my project, then ./gradlew genIntellijRuns

However, now when I try to run the game in IntelliJ I am getting this error:

Does it have to do anything with the java version?

The point of the gradle wrapper is that you do not need to download Gradle. It downloads the appropriate gradle version if necessary.

That was the problem, I couldn't run the command without installing the proper gradle version beforehand. I don't know why.

 

EDIT: It's highly likely I wasn't executing the command properly.

Thank you, moved over to the latest build for 1.14 and it is working fine now.

use gradlew when you wand to use the wrapper
