[Help needed] Problem opening project

[TehStoneMan]

I am trying to get started with NeoForge in order to update my mods, but I keep getting the following errors in Eclipse:

Archive for required library: 'D:/Minecraft Dev/MDK/.gradle/repositories/ng_dummy_ng/net/minecraft/client/1.20.4/client-1.20.4-client-extra.jar' in project 'MDK' cannot be read or is not a valid ZIP file
Archive for required library: 'D:/Minecraft Dev/MDK/.gradle/repositories/ng_dummy_ng/net/neoforged/neoforge/20.4.170/neoforge-20.4.170.jar' in project 'MDK' cannot be read or is not a valid ZIP file
Archive for required library: 'D:/Minecraft Dev/MDK/.gradle/repositories/ng_dummy_ng/net/neoforged/neoforge/20.4.170/neoforge-20.4.170.jar' in project 'MDK' cannot be read or is not a valid ZIP file
Build path contains duplicate entry: 'D:Minecraft Dev/MDK/.gradle/repositories/ng_dummy_ng/net/neoforged/neoforge/20.4.170/neoforge-20.4.170.jar' for project 'MDK'
The project cannot be built until build path errors are resolved

The problem files are 0 sized .jar files.
I have updated gradle, refreshed dependencies, cleaned and rerun the Eclipse tasks, even manually deleted these files, but they just keep returning.

Could you try updating to latest NeoGradle? It's 7.0.138 as of now.
If you still have other issues, please contact us in NeoGradle discord in relevant support channel.

This issue should be resolved with the latest NG version.

problem persists in NG 7.0.157
neoforge-21.0.151-sources.jar is not empty but doesn't contain any source files.
as result no sources attached to Minecraft and NeoForge classes in generated Eclipse project
