Launcher Version

0.46.1

Windows

Architecture

x64

Current Behavior

If I install a mod using the bug described in #740, but this time selecting the same version both on Curseforge and Modrinth, it just adds a suffix after the jar file name.

Expected Behavior

The launcher shouldn't add a suffix to the new jar file if a file with the same name is already present in the mod folder. It should either replace the old file or deny the installation.

Steps To Reproduce

I tested it in MC 1.20.1 with forge 47.3.0, but it shouldn't matter.

1. Install the latest version of GeckoLib (4.4.9) through Curseforge
   The mod is correctly installed as geckolib-forge-1.20.1-4.4.9.jar
2. Install the same version of GeckoLib through Modrinth
   You now have 2 jar files for GeckoLib in the mod folder:
   • geckolib-forge-1.20.1-4.4.9.jar
   • geckolib-forge-1.20.1-4.4.9.jar.0c60e8.jar

Anything else?

This bug keeps happening in 0.47.4, but now it adds an underscore before the file name...

It seems to have been fixed, so I'll close this issue.

Reopening it because it happened again. I was updating a mod and I got a duplicated mod.

The mod I was updating was from Curseforge, and I installed GeckoLib from Modrinth.
I think the launcher shouldn't add a suffix when a file with the same name is already present in the mod folder. It should either do nothing or ask the user if he wants to replace the current installed file.
