[m2e-dev] Scanning for changed files in a m2e compatible Maven plugin

[Anders Hammar <anders@xxxxxxxxxx>]

I'm trying to make the JAXB Maven Plugin of Codehaus Mojo compatible
with m2e as outlined in [1].

I'd like the plugin to skip execution when there are no changes to the
sources even when run from command-line (which there is already
support). Hoping to be able to use the BuildContext features for this,
I see that the DefaultBuildContext implementation does not support
this (it will always say all files are newly created).

So, my question is, do I need to implement two different code logics
to decide if the sources have changed? I.e., when
BuildContext.isIncremental() returns true I can use BuildContext, but
when it returns false I have to implement some other logic.
