ASF GitHub Bot commented on MNG-7851: ------------------------------------- candrews commented on PR #1210: URL: https://github.com/apache/maven/pull/1210#issuecomment-1651879214 > And to do what? I don't see where is the error message adjusted... what do i miss? The new test case at https://github.com/apache/maven/blob/78da8ff662d9c9e0ba87aa2138114d8fd393855c/maven-model-builder/src/test/java/org/apache/maven/model/validation/DefaultModelValidatorTest.java#L120 demonstrates how the message changes. Before this PR, the message in this case is `'modelVersion' of '4.0' is newer than the versions supported by this version of Maven: [4.0.0]. Building this project requires a newer version of Maven.` And with this PR, as this test case proves, the error message is `'modelVersion' must be one of [4.0.0] but is '4.0'.`. > Error message when modelVersion is 4.0 is confusing > --------------------------------------------------- > > Key: MNG-7851 > URL: https://issues.apache.org/jira/browse/MNG-7851 > Project: Maven > Issue Type: Bug > Components: Core > Affects Versions: 3.9.3 > Reporter: Craig > Priority: Minor > > When a pom with modelVersion 4.0 is referenced, such as this one: > {code:xml} > <project> > <modelVersion>4.0</modelVersion> > <groupId>foo</groupId> > <artifactId>bar</artifactId> > <version>0.1</version> > </project> > {code} > The error message is: > {{'modelVersion' of '4.0' is newer than the versions supported by this > version of Maven: [4.0.0].
