deleting
C:\Users\Kadir\Desktop\3\javacpp-presets\downloads
solved problem.
javacpp is not checking tar checksum.
It needs to be added as a feature to javacpp.
It will be good and important feature.
Any download shutdown or broken file or mitm attack can be stopped with that

Sounds like a good idea! If you could implement that and send a pull request, it would be most welcome. Let me know, thanks!
