nutch parsing zip files - parsing

Question

I am using nutch 1.15 to crawl the link that contains the zip files which comprises of file1.txt, file2.txt and file3.txt.
I used the parse-zip, parse-tika plugin in nutch "plugin.includes" but it is not able to crawl the content of the text files and index it.
Parsed content returns like this,
"content" : "file1.txt\nfile2.txt\nfile3.txt\n"
Why it is not able to get the contents of file1.txt, etc?
removed zip from regex-urlfilter.txt,
#-(?i)\.(gif|jpg|png|ico|css|sit|eps|wmf|zip|ppt|mpg|xls|gz|rpm|tgz|mov|exe|jpeg|bmp|js)$
-(?i)\.(gif|jpg|png|ico|css|sit|eps|wmf|ppt|mpg|xls|gz|rpm|tgz|mov|exe|jpeg|bmp|js)$
plugin.includes in nutch-site.xml:
<property>
<name>plugin.includes</name>
<value>protocol-http|protocol-httpclient|urlfilter-regex|parse-(html|text|tika|zip|metatags)|index-(basic|anchor|metadata)|query-(basic|site|url)|response-(json|xml)|summary-basic|scoring-opic|urlnormalizer-(pass|regex|basic)|indexer-elastic</value>
</property>
<property>
<name>http.content.limit</name>
<value>-1</value>
</property>
Parse-plugins.xml file:

Am I missing any configuration in nutch side?
