It turns out dependency plugin is using an old version of doxia (version
1.0, latest released is 1.4) that has known thread safety issues. You
*might* be able to work around this by adding the following dependencies to
the dependency-plugin in your pom:
<dependency>
<groupId>org.apache.maven.doxia</groupId>
<artifactId>doxia-sink-api</artifactId>
<version>1.4</version>
</dependency>
<dependency>
<groupId>org.apache.maven.doxia</groupId>
<artifactId>doxia-site-renderer</artifactId>
<version>1.4</version>
</dependency>
See
http://blog.sonatype.com/2008/04/how-to-override-a-plugins-dependency-in-mavenif
you're unfamiliar about how to do this. this might work, but might
also
bug out due to some incompatibility between 1.0 and 1.4 of doxia, I did not
try.
Please file an issue under http://jira.codehaus.org/browse/MDEP
