Description
Fixes #11399
When using
flatten-maven-pluginwithupdatePomFile=trueand<parent>expand</parent>, Maven incorrectly detected a parent cycle during the install phase. The error occurred because the consumer POM builder was usingPathinstead ofModelSourcewhen reading the flattened POM.Changes

The consumer POM builder was using
Pathinstead ofModelSourcewhen reading the flattened POM. This caused the cycle detector to incorrectly identify a cycle because it couldn't properly resolve the parent relationship context.Solution
ModelSourceincludes the necessary context (base directory, ModelLocator) to properly resolve parent POMs and avoid false cycle detection. By providing aModelSourcewith a properresolve()implementation, the parent POM can be correctly located and the cycle detection works as expected.Testing
