ASF GitHub Bot commented on MNG-8140:
-------------------------------------
cstamas opened a new pull request, #1555:
URL: https://github.com/apache/maven/pull/1555
The info is there, but we redirect user to rinse-repeat in debug mode, that
that creates a TON of output.
All is there, just tell why.

> When a model is discarded (by model builder) for whatever reason, show why it
> happened
> --------------------------------------------------------------------------------------
>
> Key: MNG-8140
> URL: https://issues.apache.org/jira/browse/MNG-8140
> Project: Maven
> Issue Type: Improvement
> Components: Core
> Reporter: Tamas Cservenak
> Assignee: Tamas Cservenak
> Priority: Major
> Fix For: 3.9.8, 4.0.0-beta-4
>
>
> Currently, when a model is discarded as "invalid", Maven 3.x shows this line
> in console:
> {noformat}
> [WARNING] The POM for org.openjfx:javafx-controls:jar:22.0.1 is invalid,
> transitive dependencies (if any) will not be available, enable debug logging
> for more details{noformat}
> And then when user uses {{-X}} and battles himself thru a TON of debug logs,
> will find the cause WHY the model was discarded (despite it was all there
> even in non-debug session).
> I want to know from first hand (and as soon as possible) WHY a model was
> discarded, so we should modify this output to:
> * do not "redirect" me at debug output
> * immediately tell me why
> Note: Maven4 already have the CLI switch {{-sadp}} "strict artifact
> descriptor policy" that will FAIL the build when it hits an "invalid" model,
> as users usually don't want invalid models in their builds (is most often
> usually some dev mistake, like using property for version/classifier while
> not defining that property). This issue affects Maven4 as well, as if the
> switch is used, build will fail due "invalid model", but user is still left
> in dark WHY.
