Cannot find class [ExtractorYoutubeDL]

[tkrn]

Version Heritrix 3.4.0-20200304

I see that #257 was pulled into the master and it was rolled out in release Heritrix 3.4.0-20200304 (https://github.com/internetarchive/heritrix3/blob/master/CHANGELOG.md#340-20200304-2020-03-04) but after defining it as documented in the notes of the ExtractorYoutubeDL.java file. I get the following error:

2020-04-06T10:36:54.321-04:00 SEVERE Cannot find class [org.archive.modules.extractor.ExtractorYoutubeDL] for bean with name 'extractorYoutubeDL' defined in URL [file:/zarchive/heritrix/jobs/test.tkrn.io/crawler-beans.cxml]; nested exception is java.lang.ClassNotFoundException: org.archive.modules.extractor.ExtractorYoutubeDL; ; Can't create bean 'metadata'

How do I load the org.archive.modules.extractor.ExtractorYoutubeDL bean?

I figured it out. I found the heritrix-contrib-3.4.0-20200304.jar compiled file and dropped in my lib path, then added to my CLASSPATH. It appears to be working.
