This is probably the same as http://jira.codehaus.org/browse/MCHANGELOG-37
But yours have more info, so I'll try and hopefully I would be able
reproduce it this time.
Thanks.

I'm having an issue with the maven-changelog-plugin, which seems to
have just crept up over the past few days, after working fine. I'm
building it from svn, creating 2.0-SNAPSHOT, using rev. 410386.
Is it working for other people? It seems the reports section of the
plugin is somehow screwing things up - if I omit it, there are no
errors (but also no reports). Here's the relevant portion of my pom:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-changelog-plugin</artifactId>
<version>2.0-SNAPSHOT</version>
<reportSets>
<reportSet>
<id>scm-changes</id>
<configuration>
<type>range</type>
<range>30</range>
<basedir>${basedir}/src</basedir>
<dateFormat>yyyy-MM-dd HH:mm:ss</dateFormat>
</configuration>
<reports>
<report>changelog</report>
<report>file-activity</report>
<report>dev-activity</report>
</reports>
</reportSet>
</reportSets>
</plugin>
Can't understand why I suddenly get this error, but maybe someone can
shed some light on it? Is plexus really trying to instantiate List
(which is abstract)? This is mvn 2.0.4, happens with all my projects
which previously worked, and the cmd is simply 'mvn site'. Other
plugins with a reports list work fine, so I'm somewhat baffled.
Haven't looked at plexus yet.
