The package structure you actually have is:
*kaqqao.nutch.plugin.selector;*
In src/plugin/element-selector/plugin.xml you have defined it as:
<extension id="*kaqqao.nutch.selector*.HtmlElementSelectorIndexer"
name="Nutch Blacklist and Whitelist Indexing Filter"
point="org.apache.nutch.indexer.IndexingFilter">
<implementation id="HtmlElementSelectorIndexer"
class="*kaqqao.nutch.selector*
.HtmlElementSelectorIndexer"/>
</extension>
It aint the same and thats why it cannot load that class at runtime. Make
it consistent and try again.
It worked at my end after changing the package structure to
kaqqao.nutch.selector
