JRuby test builds do not generate grammar_file_scanner.rb

[headius]

There seems to be some file dependency issue with lib/racc/grammar_file_scanner.rb. It gets generated automatically based on dependencies when running rake test on CRuby, but it does not get generated on JRuby.

This causes the test suite to fail to start:

/home/travis/.rvm/rubies/jruby-9.2.4.0/bin/jruby -w -I.:lib/racc:lib:bin:test:. -e 'require "rubygems"; require "minitest/autorun"; require "test/test_chk_y.rb"; require "test/test_directed_graph.rb"; require "test/test_grammar_file_parser.rb"; require "test/test_racc_command.rb"; require "test/test_scan_y.rb"; require "test/test_scanner.rb"' --

I do not have an explanation for this, but I suspect some combination of rake-compiler and the various JRuby-specific conditionals in the Rakefile are interfering somehow. Note that the file does get generated when packaging the full gem, but it is not generated for rake test. For whatever reason, the test target does not end up depending on this file in the same way it is on CRuby.

I am patching it temporarily for #93 by forcibly generating it in the test script.

Is this still a thing?
