Attach sources button not working with maven mirror configured

[Nicolò Boschi - Diennea <ni...@diennea.com>]

Hi everyone,

I usually work on java project managed with maven, using Netbeans 10. I recently configured a mirror in my settings.xml:
<mirrors>
        <mirror>
            <id>mavencentralproxy</id>
            <name>Maven Central mirror</name>
            <url>https://xxxx</url>
            <mirrorOf>central</mirrorOf>
        </mirror>
</mirrors>

It works well as a maven repository mirror but now I'm not able to use "Attach Source" button in order to download dependency's code source

Removing the mirror, the feature resumes to work.

I did not found any issue about this on netbean JIRA

If someone could indicate me where looking for in source code I will be happy to send a PR

Maven: 3.6.0
Netbeans: 10
OS: Fedora

Thanks

Nicolò Boschi
