Question

I’m using JRuby and need to get specific version of a gem:

C:\>gem list activerecord-jdbcsqlite3-adapter --remote --all

*** REMOTE GEMS ***

activerecord-jdbcsqlite3-adapter (1.2.6, 1.2.5, 1.2.2.1, 1.2.2, 1.2.1, 1.2.0, 1.1.3, 1.1.2, 1.1.1, 1.1.0, 1.0.3 java, 1.0.2 java, 1.0.1 java, 1.0.0 java, 0.9.7
java, 0.9.6 java, 0.9.5 java, 0.9.4 java, 0.9.3 java, 0.9.2, 0.9.1, 0.9.0.1, 0.9, 0.8.2, 0.8.1)

Ok, so I put this in Gemfile:

gem 'activerecord-jdbcsqlite3-adapter', '=1.0.3 java'

But bundle doesn’t undestand that:

C:\bundle install

There was an error in your Gemfile, and Bundler cannot continue.

What am I doing wrong?

Answer 1

I think you’re looking for:

gem 'activerecord-jdbcsqlite3-adapter', '=1.0.3', :platforms => :jruby

But if you’re using jruby you probably don’t need the platfrom part.
