When I check out a project using the jaxb2-maven-plugin, I get the error:
An internal error occurred during: "Building workspace".
Provider org.apache.xerces.jaxp.SAXParserFactoryImpl not found
However if I do the same on the command line it works fine!
So it seems to have something to do with the m2 plugin...
I have tried with 0.9.5 + Eclipse 3.3 and 0.9.6 + Eclipse 3.4 both with the same issue and also tried using both the embedded and an external maven (2.0.9) all with the same result.
It also seems that this behaviour breaks the project since Eclipse will then remove the target/generated-classes from the classpath.
The workaround right now is to :
1 - Check out and ignore this error (the project now has errors and is in a bad state)
2 - Manually to "Run as"->"Maven generate sources"
3 - Sync with SVN and do "Update and override" on the .classpath file to get back the stuff Eclipse broke
4 - Refresh the project
All this is naturally painful and not very practical... :-(
Again I can re-iterate that this works perfectly in maven (outside eclipse) and the build server (continuum) builds this example project all the time without errors.
I have attached my full environment from Eclipse in a text file and also a sample POM file of one of the projects with this problem.

org.apache.xerces.jaxp.SAXParserFactoryImpl not found error with projects using jaxb2-maven-plugin?
I've reproduced that error. It seems like embedded maven used when updating source folders have different classloader structure and it does not see xerces required by jaxb. That won't be an easy to fix, however there is a workaround that you can use.
See attached pom.xml which declares required depndencies, including xerces, as jaxb plugin dependencies. With this it works for in the ide and in the command line.
