    Description

      I discovered this NPE whilst running some integration tests for our Repoaint IO tiles-maven-plugin:

      [INFO] Scanning for projects...
      [INFO] --- tiles-maven-plugin: Injecting 1 tiles as intermediary parent artifacts for com.test:reporting-tiletest...

      This was triggered when running our sitereporting test ( https://github.com/repaint-io/maven-tiles/tree/master/src/it/sitereporting-tiletest ) and doesn't trigger an NPE using Apache Maven 3.5.3, but does with the current SNAPSHOT of 3.6.2.

      The problem lies when Maven is building the model from https://github.com/repaint-io/maven-tiles/blob/master/src/it/sitereporting-tiletest/tile-tile/tile.xml#L35 and can be fixed by applying the patch found at https://www.dropbox.com/s/9gficrmlgxl2jd0/0001-Fix-NPE-thrown-from-DefaultReportingConverter.patch?dl=0 (for some reason I could not attach the patch to the ticket).
