How do I get Artifactory to use the latest (instead of the oldest) Snapshot artifact?

Question

I am using jennkins pipelines, maven and artifactory to build a product, MyProduct.

Plugin A uses the following Artifactory Snapshot Repository.

<distributionManagement>
    <snapshotRepository>
        <id>mvn</id>
        <url>https://bin.mydomain.ch/artifactory/myproduct-repo.mvn/</url>
        <uniqueVersion>false</uniqueVersion>
    </snapshotRepository>
</distributionManagement>

Plugin A builds without a problem and seems to upload to the Company Repo and MyProduct Repo.

Somewhere in the build process something went wrong and the two repositories are not synced, there is an extra artifact in the Company Repo, "*-110.jar & *.110.pm".

When I build plugin B it fetches the dependencies out of the Company Repo and for some reasons it fetches the 110 Snapshot which is the oldest and I get a compilation error. The Company Repo maven-metadata.xml is pointing to artifact 110, whilst the maven-metadata.xml MyProduct Repo is pointing to artifact 37 (the latest and greatest).

How can I tell plugin B to use MyProduct Repo, or at least to take the newest SNAPSHOT artifact?

Is there any jenkins pipepline magic that I can use to emulate false, in other words push to the repository without timestamps (and also pull them)?

How can I recreate maven-metadata.xml on the Company Repo?

<distributionManagement>

        <updatePolicy>always</updatePolicy>
    </snapshotRepository>
</distributionManagement>

Add updatePolicy and set its value to "always". This will always pull the latest version of dependencies from the specified URL.

Setting uniqueVersion to false is another topic altogether (Semver violation).

I wouldn't ever recommend doing away with timestamps in Artifactory. That information is valuable for a number of reasons. I understand that you're just looking for a solution to your problem, but by removing timestamps, you are essentially putting a band-aid over an open wound.

Not sure what you mean here. This is updated automatically. You shouldn't be forcing Maven to do anything with this file.
