Hello, I cloned javacpp and javacpp-presets successfully but when I try to do the command mvn clean install, it gives this error and I can't process any further:

That's just a network failure. Try again until it downloads successfully.

I tried several times but it still gave this error. Is there any other solution that I can use?

Your network may be blocking it, ie a firewall. Try using a proxy

Make sure you're retrying with mvn -U ...

This does not work either.

BTW, there is no need to build anything by yourself. Everything is all available as snapshots: http://bytedeco.org/builds/
