maven-jaxb2-plugin fails in Eclipse M2E, but works fine from command line #315

We're using maven-jaxb2-plugin v0.14.0 in many projects. It works fine from the command line. I'm posting this here not because I think there's something wrong with the plugin, but because you may have heard of this problem.

In Eclipse, using the M2E plugin, we get exceptions in the problems view like this:

It appears that I can just ignore this, but it is hard to ignore. I can't tell for certain whether it's causing any functionality problems in Eclipse.
