VersionParsingException being thrown on runClient

[Lucas-Cerqueira]

I am getting the following error when running the runClient task:

> Task :runClient FAILED

# Done to increase the memory available to gradle.

# Fabric Properties
# check these on https://fabricmc.net/versions.html
minecraft_version=1.17.1
yarn_mappings=1.17.1+build.63
loader_version=0.12.4

# Mod Properties
mod_version = 1.0.0
maven_group = com.example

# Dependencies
fabric_version=0.41.3+1.17

Apparently "minecraft-" is being appended to the game version and fails on VersionParser.parseSemantic(version) inside the Builder constructor.

Your problem likely lies in your buildscript. What does minecraft() look like?

I'm new to this, and I'm not really sure what that means

[CodeF53]

For people running into this in the future,

./gradlew --refresh-dependencies

[greygrey1]

That did not work for me

[jakiki6]

didn't work for me either

If you are also running into this issue, is your message Could not parse version number component 'minecraft', or is some other string listed instead of minecraft? You should post the full error that you are running into even if it appears similar to another person's error at first glance.
