Is updating to netbeans 11 an option? – Thorbjørn Ravn Andersen Apr 03 '21 at 22:08 — Thorbjørn Ravn Andersen, Apr 03 '21 at 22:08

Maven central switched from HTTP to HTTPs.

In order to use HTTPs, you could either update your maven installation or explicitely add the repository with HTTPs:

<repositories>
    <repository>
        <id>central</id>
        <url>https://repo.maven.apache.org/maven2</url>
    </repository>
</repositories>

If you add this to your pom.xml, it should use maven central over HTTPS as you explicitely specified the repository URL for this project.
