Maximilian Michels commented on MNG-5899:
-----------------------------------------
Does the Maven community plan to address this issue which affects other Apache
projects through the Shade plugin (MSHADE-206, FLINK-3158)? It looks to me the
original changes introduced in
https://github.com/apache/maven/commit/be3fb200326208ca4b8c41ebf16d5ae6b8049792
are API breaking and trade off correctness of the build model against a
performance optimization.
How about introducing a Maven option to explicitly turn on caching of parsed
POMs? That wouldn't break functionality for existing users and still give users
the option to build faster.

> Key: MNG-5899
> URL: https://issues.apache.org/jira/browse/MNG-5899
> Project: Maven
> Issue Type: Bug
> Affects Versions: 3.3.1, 3.3.3
> Reporter: Trask Stalnaker
>
> This works with maven 3.2.5 and prior, but does not work with the latest
> releases (3.3.1 and 3.3.3), or master (tested against 3.3.7-SNAPSHOT).
> I did some bisecting and found the commit that caused the breakage:
> https://github.com/apache/maven/commit/be3fb200326208ca4b8c41ebf16d5ae6b8049792
> In particular, this commit introduced some code to not rebuild the model if
> it was already loaded during reactor resolution.
> This is causing maven not to use the dependency reduced pom created by the
> maven-shade-plugin.
> Removing this code fixes the situation. I'm hoping that code was just
> introduced as a performance optimization, and that I haven't broken anything
> functionally by removing it (the tests still pass at least).
> I will submit a pull request with the change for review.
> Here is the original maven-shade-plugin issue as reported by the Apache Storm
> team: https://issues.apache.org/jira/browse/MSHADE-206
