Unable to create Maven Java project in VS Code

[post-war]

I am unable to create Maven java project from archetype in VS code. I have given below the error I get. I have searched and found many have reported the same since 2019. I have tried all the suggested solutions but to no avail. I am using Windows 10.

You can copy the full command (cmd.exe /c ""......my proj""), run it in an external cmd prompt. See if that would work or any error?

I tried after removing outer quotes, but different errors. ( fyi, I can create Maven project in another pc without errors) I think the command is correct. It starts executing but gets into some errors, full log is below.

No firewall issue as I can reach https://repo.maven.apache.org/ from browser

I don't see such error, using the same mvnw embedded in this extension, as below. From the error log you provided, it's likely related to your networking status, e.g. are you behind some proxy/VPN, or some self-issued certs required, etc... The root cause should be that "repo.maven.apache.org" failed to be resolved. I myself guess it's related to DNS/SSL certs.

[Eskibear]

Or you can download a Maven distribution on your own, and add it into PATH env. use mvn to run almost the same command in CMD, see if it works. If it works, we have a setting maven.executable.path for you to specify.

Thanks, DNS/SSL cert must be the likely cause. I will try with mvn directly.

I'm closing it as it's probably networking issue. Feel free to reopen it if anything new is found.
