Option to use system installed closure-compiler.jar

[junaruga]

Hi,
Right now this closure-compiler gem package is using fixed version: closure-compiler.jar which is bundled inside of the package.
However I would like to use system installed closure-compiler.jar from this gem package.

I am using Fedora 23. And there is a closure-compiler package.

# rpm -qa | grep closure-compiler
closure-compiler-20141215-3.fc24.noarch

# rpm -ql closure-compiler
...
/usr/share/java/closure-compiler/closure-compiler.jar
...

For example one of the popular gem package: nokogiri has the option to use system installed library.

https://github.com/sparklemotion/nokogiri

In Nokogiri 1.6.0 and later libxml2 and libxslt are bundled with the gem, but if you want to use the system versions
at install time, set the environment variable NOKOGIRI_USE_SYSTEM_LIBRARIES or else use the --use-system-libraries argument. (

I would be happy if this kind of option for the closure-compiler was implemented.

How do you think?

Thanks.
