[jira] [Commented] (MNG-8301) [REGRESSION] Can't build a project without modelVersion=4.1.0 but with 4.1.0 (beta-4) XSD

["Maarten Mulders (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MNG-8301?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17888910#comment-17888910 ] 

Maarten Mulders commented on MNG-8301:
--------------------------------------

I have created a PR with an integration test that illustrates the issue: [apache/maven-integration-testing #386|https://github.com/apache/maven-integration-testing/pull/386].

I have also run a {{git bisect}} on Maven using this project with {{mvn validate}} as the verification. The outcome is that [2d224623|https://github.com/apache/maven/commit/2d224623a32770401e0a5a8aecf1333797f89b8e] is the first bad commit. [~gnodet], you are the author of that commit - maybe you have any clue?

> A project whose pom.xml refers to the [4.0.0-beta-4 XSD|https://maven.apache.org/xsd/maven-4.1.0-beta-4.xsd] and that lacks a {{modelVersion}} element used to be buildable with Maven 4.0.0-beta-4. Maven would infer from the XSD that it should use _modelVersion_ 4.1.0.
> With the current snapshots of 4.0.0-beta-5, it can no longer be built:
