update-parent does not respect -DallowMajorUpdates (original) (raw)

The update-parent goal does not respect the properties allowMajorUpdates, allowMinorUpdates and allowIncrementalUpdates that use-latest-version goal uses. This is somewhat confusing (even though the documentation states that the property is not used)

Updating the parent version will update to a new major version even if allowMajorUpdates is declared

$ mvn versions:update-parent -DallowMajorUpdates=false

Since, for example the java version used and other breaking changes might be inherited from the parent, there should be a way to update the parent without updating to a new major version
