------------------------------------------
I've tried with the line mar.recordFingerprints(); commented but I see no
difference in build time.
>From MavenFingerPrinter it seems that fingerprinting is required to keep track
>of dependencies so maybe it is necessary to launch others build when snapshot
>dependencies change or to use only build changed modules option.
Note that the I use maven jobs with automatic artifact archiving disabled.
> Maven artifact fingerprints are computed and recorded twice

> Priority: Minor
>
> The artifacts which are produced by a maven job have their artifacts
> fingerprinted twice. Once in MavenFingerprinter and once in
> MavenArtifactArchiver (*). This adds unnecessary overhead to maven jobs.
> Proposal: as fingerprints are needed in the MavenArtifact records generated
> in the MavenArtifactArchiver, it probably doesn't make much sense to remove
> the fingerprinting from there. Instead, I'd propose to fingerprint all 'used'
> artifacts in the MavenFingerprinter and all 'produced' artifacts in the
> MavenArtifactArchiver
> *) Note that fingerprints are even generated in MavenArtifactArchiver if
> automatic artifact archiving is disabled
