SOLVED! Look at posts below to find a quick tutorial how o fix this issue.

***

 

1. Problem

Starting the project using Run Start crashes the game. When I start the project by using gradlew runClient it works. Another problem is that I need to set an additional enviro variable named "assetDirectory", as a value I used "C:\Users\MyUserName\AppData\Roaming\.minecraft\assets". I did this because it couldn't find asset path under this enviro variable in Start.class: 

String assets = System.getenv().containsKey("assetDirectory") ? System.getenv("assetDirectory") : "assets";

2. Repro

Tried on 2 different machines, result is the same. Im using Eclipse. Here's my repro:

  1. downloaded the most recent Recommended Forge (forge-1.14.4-28.1.0)
  2. installed Java 8
  3. gradlew eclipse
  4. gradlew build
  5. open eclipse and load project with default Example Mod
  6. changed nothing in project files, just want a sanity check launch

 

3. Output

genEclipseRuns didn't helped, still having the same error. What else can I check?

 

I launched this command, there's output: 

PS D:\Test> .\gradlew genEclipseRuns

And after that I reopened Eclipse, clicked Run Start (Start - mcp.client configuration) and have the same result:

Thanks! That solved my issue. I checked configurations once again and found generated by the task. For some reason this run configuration was not set by default in my case

 

Here is how to solve this problem if you found this topic with similar issue:

 

Open Run Configurations

From the Run Configurations expand Java Application and choose your config (runClient for example) and press Run.

After that just by pressing Run it will automatically start the game with selected configuration every time until you change it on something else (like a runServer).
