Stuart McCulloch commented on MNG-3042:
---------------------------------------
FYI, you only need to propagate values using reflection if you override the
field, ie. you declare a field in your mojo that "hides" a field of the same
name in original mojo. You only usually need to do this if you need to change
the default, or want access to the field - although in the latter case you
could use reflection to read the field rather than override it. (
interestingly, if the overridden field is a @parameter then your new field will
be injected instead of the original - but if it's an @component then it appears
the original field is injected rather than the original )
Note that you can read and write private fields using reflection - you just
need to use setAccessible(true) on the field to make it accessible, as shown in:
http://www.ops4j.org/projects/pax/construct/maven-pax-plugin/xref/org/ops4j/pax/construct/util/ReflectMojo.html
btw, in the maven-pax-plugin I extend a number of different mojos and override
a couple of private fields, so I know this works in practice.
