Can not upload jar file to nexus 3 wheras the pom file is uploaded

Question

I have a simple spring boot application that I deploy to the repository manager nexus via the command mvn clean deploy. The issue is after running the maven command, I can see that the packaged pom file is uploaded whereas the jar file is not uploaded with an error message.

The pom file:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</project>

And I am getting the error:

Even I add the packaging jar tag to the pom file, it did not work. As the error log recommend, I run the mvn deploy on debug mode, I noticed this indication but I don't undestand what it means:

Network problem, hard to figure what's going on.

Check:

• That your nexus is available with a browser
• Check your repository is browseable.
• Check that your repository path is correct and is accessible in nexus repository options
• Check that there is not a firewalld on your computer and/or nexus server that prevent you from connecting.
• Are you sure your nexus does not use https? These kind of errors messages are often related to TLS issues (incompatibilty).
• Check your repository accept SNAPSHOT
