Bug#832868: mina2: FTBFS: Plugin org.apache.xbean:maven-xbean-plugin:4.5 or one of its dependencies could not be resolved

[Emmanuel Bourg]

This looks like an xbean bug. maven-xbean-plugin has an optional
dependency on Ant so the libxbean-java package doesn't have to depend on
ant, but the XBeanMojo class does use BuildException from Ant to report
errors [1]. It should use a MojoExecutionException from Maven instead,
or the Ant dependency should become mandatory.
