Hi, whenever I execute gradlew genEclipseRuns this error shows up. Here's the stacktrace:

I'm nowhere near a pro, and I do not feel very qualified to answer this. However, that said, I do recommend deleting your Minecraft resource files (the folders "assets" "versions"  and "libraries") in "%appdata%\.minecraft" (on Windows) and then running Minecraft 1.16.4 from the vanilla launcher again.

it worked! thank you very much.

If you would like, please read further for an explanation of what happened (in the spirit of learning how to debug)

 

If you look below, at the section titled "What Went Wrong" in your error, try to read it, as though it were plain English.

Execution failed for task ':downloadAssets'.
> Failed to get asset: minecraft/sounds/music/game/calm2.ogg
  Some assets failed to download or validate, try running the task again.

Do you see where it says "failed to get asset" and gives an asset path to a music file? Below that line, it also says that "some assets failed to download or validate."

 

In other words, it is saying "Hey, we found a problem with the game. This was probably a one-off issue." Because it happened multiple times, I told you to delete the problem files and let your machine reacquire them from Microsoft servers.

 

I hope you found this breakdown useful, and I hope that I gave you some useful insight.
