kandi X-RAY | activerecord-jdbc-adapter Summary
ActiveRecord-JDBC-Adapter (AR-JDBC) is the main database adapter for Rails' ActiveRecord component that can be used with JRuby. ActiveRecord-JDBC-Adapter provides full or nearly full support for: MySQL, PostgreSQL, SQLite3 and MSSQL* (SQLServer). Unless we get more contributions we will not be supporting more adapters. Note that the amount of work needed to get another adapter is not huge but the amount of testing required to make sure that adapter continues to work is not something we can do with the resources we currently have. Versions are targeted at certain versions of Rails and live on their own branches. Note that JRuby 9.1.x is end-of-life. We recommend Java 8 at a minimum for all versions.

QUESTION
I'm trying to migrate an existing Ruby on Rails App (Ruby 2.3.3p222, Rails 5.0.0.1), developed by an former colleague, to JRuby. The app is running without any issues using aforementioned Ruby version. You can find the original Gemfile as Gemfile Ruby in the appendix.
As I'm new to Ruby and not sure about what's wrong, I provide all the changes I did so far (see Gemfile JRuby in the appendix for the resulting Gemfile) to migrate the app to JRuby.

I replaced gem 'pg', '~> 0.21.0'

and could be solved in issue #891. As all changes were made on branch 50-stable

I want to install Redmine on my Raspberry Pi2. When I tried to run the command sudo bundle install --without development test rmagic
I got this as output:
Don't run Bundler as root. Bundler can ask for sudo if it is needed, and installing your bundle as root will break this application for all non-root users on this machine.

Answered 2017-Mar-25 at 01:33Getting a new line with >
at the beginning after pressing Enter in the shell is usually a sign of unbalanced quoting. Are you sure you entered the gem install
commands correctly?
Your errors when running bundler
look like network problems. Most probably on your side, but rubygems.org has had connectivity problems a couple times in the past so it's not entirely impossible the problem was on their side or somewhere in between. Retry a couple hours later and it should simply work.
