--------------------------------

             Summary: Relative parent POM resolution failing in 3.5.0 with complex multimodule builds
                 Key: MNG-6261
                 URL: https://issues.apache.org/jira/browse/MNG-6261
             Project: Maven
          Issue Type: Bug
    Affects Versions: 3.5.0
            Reporter: Dawid Weiss
            Priority: Minor
         Attachments: repro.zip

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:

> mvn validate
[FATAL] Non-resolvable parent POM for com.carrotsearch.lingo4g:lingo4g-public-bom:[unknown-version]: Could not find artifact com.carrotsearch.lingo4g:lingo4g-public:pom:1.6.0-SNAPSHOT and 'parent.relativePath' points at wrong local POM @ line 5, column 11
...
(and many follow).

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).
