I am trying to run my first project "Calculator" on netbeans-11 july version and it gives this error -
Plugin org.codehaus.mojo:exec-maven-plugin:1.5.0 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.codehaus.mojo:exec-maven-plugin:jar:1.5.0: Could not transfer artifact org.codehaus.mojo:exec-maven-plugin:pom:1.5.0 from/to central (https://repo.maven.apache.org/maven2): Connect to repo.maven.apache.org:443 [repo.maven.apache.org/151.101.196.215] failed**: Connection timed out: connect -> [Help 1]

Maven cannot connect to maven central. Are you behind a company firewall? — Thorbjørn Ravn Andersen, Sep 05 '19 at 21:56
I have allowed the netbeans app through all firewalls. but still it is showing the same error. — Akash Gupta, Sep 06 '19 at 04:23
Also, if you are working for a company, please check if you have added settings.xml in your .m2 local (C:\Users\*****\.m2\repository) with proper maven central URL and other details. If not then please add it with the proper maven central URL(better to ask your peers to share it). — Brooklyn99, Sep 06 '19 at 05:12

I had the same issue, make sure your editor have finished downloading all Maven requirementents, also try to update your project under de Maven menu. Finally, make sure you are not behind a proxy, if that is the case, configure your settings.xml like in this answer.
