Need to download artifacts from MavenCentral if it is not available in the internal repository

Question

I have following configurations on my settings.xml to get organization's internal artifacts.

<mirrors>
    <mirror>
        <id>internal-repository-1</id>
        <url>http://local.host/repository/internal/</url>
        <mirrorOf>*</mirrorOf>
    </mirror>
</mirrors>

Normally it has every artifacts to build internal projects. But I want to download some other artifacts from MavenCentral. Since I'm using above mirror configurations it will not check artifacts on MavenCentral.

I want to know is there any way to download artifacts from MavenCentral if it is not available in our internal repository by modifying settings.xml

I have already refer following questions and did not help.

maven repository mirrors

Can I add maven repositories in the command line?

Your internal repository is probably a Nexus or Artifactory. Just add MavenCentral as a proxy repository in your internal repository. Then you will be able to access everything from MavenCentral through the internal repository.

I don't have permission to done changes in the internal repository. Is there any way to do it using settings.xml? – Chathura Buddhika Jun 29 '17 at 12:59

If your internal repo does not want to proxy to maven central repo you can disable requests for central to it like:

<mirrors>
    <mirror>
        <id>internal-repository-1</id>
        <url>http://local.host/repository/internal/</url>
        <mirrorOf>*,!central</mirrorOf>
    </mirror>
</mirrors>

Ensure you have central repository declared as the last one in your repositories list as maven 3 searches from top to bottom and you want central to be the fallback.

If anyone have the same problem, putting following code block in to settings.xml also worked.

<profiles>
    <profile>
        <id>profile-1</id>
        <repositories>
            <repository>
                <id>internal-repository-1</id>
                <url>http://local.host/repository/internal/</url>
            </repository>
        </repositories>
    </profile>
</profiles>
<activeProfiles>
    <activeProfile>profile-1</activeProfile>
</activeProfiles>
