How well does m2eclipse deal with maven plugins?

Question

In general, how well does m2eclipse deal with Maven plugins that modify or amend lifecycle phases?

In particular, I have a project that has a maven-clean-plugin extension to remove an extra generated directory (not in target/) using the configuration filesets tag. This works when running mvn at the command line but not when doing a clean in Eclipse. Is there any way to get m2eclipse to process that plugin?

Another example is flexmojos; there's a lot that can be configured with the flexmojo plugin but those parameters don't seem to get imported by m2eclipse.

Is the integration solely ad-hoc? If m2eclipse embeds Maven, why can't the plugins be executed directly using the underlying pom.xml configuration?

Decently, to my experience. At least for plugin bound to phases from the default lifecycle.

In particular, I have a project that has a maven-clean-plugin extension (...). This works when running mvn at the command line but not when doing a clean in Eclipse. Is there any way to get m2eclipse to process that plugin?

What the clean plugin "extension" is doing and what you're doing (calling mvn clean from Eclipse? calling Project > Clean?) is unclear - at least for me. But maybe have a look at MNGECLIPSE-823 or MNGECLIPSE-156. And don't hesitate to clarify :)

Another example is flexmojos; there's a lot that can be configured with the flexmojo plugin but those parameters don't seem to get imported by m2eclipse.

I don't do flex so the above is too vague for me. But providing a more concrete example might help.
