Apparently, when I try to download the .jar files for snapshot 18w07a, it fails and says that the sounds failed to download, here's the full message:
Unable to save download. sounds.json
Name: sounds.json
URL: http://resources.download.minecraft.net/34/3417b582d43faf87529f4e9353a6d1eb2546f52d

The process cannot access the file because it is being used by another process

Please fix this bug, I really want to see the latest adding!
