Error loading TikaLanguageIdentifierUpdateProcessorFactory

I am trying to add Tika's language detection feature to Solr (6.5.0). I added the following line to the solrconfig.xml file:

<lib dir="C:\Program Files\SOLR\server\tikaLib\" regex="tika-app-1.14.jar" />

And langid configuration in solrconfig.xml:

<updateRequestProcessorChain name="langid"> 
    <processor class="org.apache.solr.update.processor.TikaLanguageIdentifierUpdateProcessorFactory"> 
        <str name="langid.fl">text,title,subject,description</str> 
        <str name="langid.langField">language_s</str> 
        <str name="langid.fallback">en</str> 
    </processor> 
    <processor class="solr.LogUpdateProcessorFactory" /> 
    <processor class="solr.RunUpdateProcessorFactory" /> 
</updateRequestProcessorChain>

However I got the error below:

Caused by: java.lang.ClassNotFoundException: org.apache.solr.update.processor.TikaLanguageIdentifierUpdateProcessorFactory
at java.net.URLClassLoader.findClass(Unknown Source)

you need to add all jars Tika depends on, those are in 

contrib\extraction\lib\

just add a similar line to solrconfig.xml to the one you added above:

  <lib dir="${solr.install.dir:../../../..}/contrib/extraction/lib" regex=".*\.jar" />

should do it.
