Looking at the exception message, it seems that the version of Ant used for those who implemented the class com.sun.tools.xjc.XJCTask is different from the version of Ant used by the maven-antrun-plugin.
You should try to find out what versions are used by each of them and then try to use compatible version for both. Maybe the short way to fix it is ask someone of the team behind XJCTask 's implementation. Other ways you can try is google for "A class needed by class com.sun.tools.xjc.XJCTask cannot be found: org/apache/tools/ant/DynamicConfigurator". I did it and found good tips on solving this. (one said upating jre worked for him) Regards, Rafael.
