add an option to exclude parent from properties updates

[jonathanlermitage]

Since version 2.13.0, the display-property-updates goal shows many properties updates for Spring Boot based projects.
Spring Boot projects use a Spring Boot parent pom which declares a BOM with many dependencies and their corresponding version properties.
Even if we don't actually use these dependencies (they are declared in a dependencyManagement block), the display-property-updates goals now shows updates for all of these properties.
I think it would be useful to provide a parameter that allows us to ignore version properties updates from parent's pom. If this parameter already exists, could you please update the documentation https://www.mojohaus.org/versions-maven-plugin/display-property-updates-mojo.html?
Thanks!

How to reproduce: create a sample Maven project with https://start.spring.io/. You can also test this project https://github.com/jonathanlermitage/spring-mvc-tiny-sample. Then, invoke display-property-updates and see the proposed properties updates.
With plugin 2.12.0 I get:

[andrzejj0]

This is a result of fixing #367.

Indeed, very valid request. I'll definitely consider it.

[andrzejj0]

New option: includeParent, default true.

Adding the same option to property-updates-report.

[edwinvanderham]

Should this includeParent property not also be added to update-properties?

Since upgrading from 2.12.0 to 2.13.0, the update-properties for a reactor project takes much much longer and is way more verbose than before. In every reactor module, I get the same message about properties being unchanged, whereas before I would only see this in the root module.

[andrzejj0]

I agree that it's more chatty than before. It's a side effect of #367. I think it doesn't really add any value there. While it will discover property updates from parent POMs, it won't be able to modify them anyway. So it's a genuine bug, which needs to be addressed, not just a question of providing the property there.

What's worse, versions-changes.xml will record a change that did not occur.

[andrzejj0]

@edwinvanderham could you please create a new issue? Thanks Created #837

[andrzejj0]

Edit -- it does matter after all if the child POM redefines a property defined and used in the parent. - #582

So, I'll add includeParent, equal to true.

[edwinvanderham]

@ajarmoniuk thank you for the quick response
