Yea looks like the Facter readlines method doesn't exist.
http://ruby-doc.org/core-1.8.7/IO.html#method-c-readlines
You will need to use ruby's readlines and probably clean up the lines as
well with chop.
Revised edition: (untested, and probably full of syntax errors)
Facter.add(:java_versions1) do
setcode do
file = '/home/suppalapati/java.txt'
if File.exists?('/home/suppalapati/java.txt')
lines = File.readlines( file, "\n")
if ! lines.nil?
versions = lines.collect {|command| `#{command.chop}`}
else
versions = `java -version`.to_a
end
versions.join(",")
else
# poor mans debugger
versions = "Can't find file: #{file}"
end
end
end
Please read : https://docs.puppetlabs.com/facter/1.7/custom_facts.html
See section about loading custom facts. This will give you the chance to
test on your machine.
check syntax ruby -c <facter_file.rb>
