Disable a dependency when generating java sources from XSD with xjc

I have recently added org.eclipse.persistence:eclipselink:2.6.0-M3 to my maven dependencies.

The problem is that I'm using org.codehaus.mojo:jaxb2-maven-plugin:xjc goal to build java sources from my *.xsd XML schemas and that now I have that error when building:

I've seen that eclipselink-2.6.0-M3.jar indeed declares /META-INF/services/com.sun.tools.xjc.Plugin which requires com.sun.tools.xjc.model.CPropertyVisitor2 which is not in my dependencies.

Is there a way to tell xjc not to use plugins or to change dependencies when executing xjc maven goal?

Solution

  • I found that workaround (which is not really satisfying me as it's not really answers my question): adding com.sun.xml.bind:jaxb-xjc:2.2.11 as a provided dependency of my project.
