Short answer, this is not supported by m2e.
Manipulating MavenProject model at runtime breaks some fundamental
assumptions m2e makes about projects and something I have no plans to
support in m2e. I think custom packaging type is a better way to add new
plugin executions to projects without having to explicitly configure
<plugin> elements in pom.xml.
