Writing a Jeweler Rakefile that adds dependencies depending on RUBY_ENGINE (ruby or jruby)
- by Matt Zukowski
I have a Rakefile that includes this:
Jeweler::Tasks.new do |gem|
# ...
gem.add_dependency('json')
end
The gemspec that this generates builds a gem that can't be installed on jruby because the 'json' gem is native.
For jruby, this would have to be:
Jeweler::Tasks.new do |gem|
# ...
gem.add_dependency('json-jruby')
end
How do I conditionally add the dependency for 'json-jruby' when RUBY_ENGINE == 'java'?
It seems like my only option is to manually edit the gemspec file that jeweler generates to add the RUBY_ENGINE check. But I'd rather avoid this, since it kind of defeats the purpose of using jeweler in the first place.
Any ideas?
