Subject [jira] [Commented] (MNG-6261) Relative parent POM resolution failing in 3.5.0 with complex multimodule builds
Date Mon, 06 Aug 2018 21:55:00 GMT


Robert Scholte commented on MNG-6261:

I think the cleanest fix is to wrap pomFile in a {{FileModelSource}} and do an {{equals()}}
with {{expectedParentSource}}. This also means that it is easy to unittest , verify all combinations
of drive letters with FileModelSource.equals(). Hence I marked it as for-the-grabs. Now waiting
for somebody to pick this up.

> In my effort to upgrade an existing (fairly complex) Maven build to Java 1.9.0 I updated
Maven to 3.5.0 (from 3.3.9). Unfortunately I get errors when the project's modules are resolved:

> This build has a correct pom parent-structure (a tree), but is fairly complex -- the
submodule hierarchy is not aligned with parent-child pom hierarchy (it's best to look at the
repro code to understand how it's structured).
> However, it's been working correctly with all prior Maven versions and I wonder if it's
a regression bug or maybe underspecified Maven requirement (that should be enforced with a
warning and not lead to this odd runtime message).
