Description

The patch for MNG-6311 introduces a regression in ProjectBuilder due to missing cache invalidation when content change.

It was identified as a potential issue by fbricon on Oct 10, yet no further investigation happened and Maven 3.6.0 was released with this regression.
This regression prevents Eclipse m2e (and probably most APIs using the ProjectBuilder for a longer session which allows pom.xml files to be modified) from adopting 3.6.0.
