I’m trying to use warble to build a war file, and I’m getting:
cp
/Users/jamesmoore/.gem/jruby/1.8/specifications/activerecord-jdbcmysql-adapter-0.9.2.gemspec
tmp/war/WEB-INF/gems/specifications/activerecord-jdbcmysql-adapter-0.9.2.gemspec
rake aborted!
Cannot load gem at
[/opt/local/lib/ruby/gems/1.8/cache/activerecord-jdbcmysql-adapter-0.9.2.gem]
in /Users/jamesmoore/dev/projects/ga.git
/Users/jamesmoore/dev/jruby-1.4.0/lib/ruby/site_ruby/1.8/rubygems/format.rb:41:in
`from_file_by_path’
(See full trace by running task with --trace)
It looks like it’s trying to pull the activerecord-jdbcmysql-adapter
from the MRI gem directory instead of the ~/.gem version where it’s
installed.
Suggestions?
Versions:
jamesmoore@james-moores-macbook-pro-2:~/dev/ga$ gem -v

Do you have GEM_HOME set as an environment variable?

Put this in config/preinitializer.rb:
if defined?(::JRUBY_COMPILED_WAR)
Set the gem home to the gem path when running as a war, to ensure
we don’t pick up any system gems, only gems bundled in the war
ENV[‘GEM_HOME’] = Gem.path.first
end
The ::JRUBY_COMPILED_WAR is a switch which we only set if we are
running from a WAR, if you always run from a war (which I wouldn’t
recommend unless you like watching paint dry) you can omit that.
