generating WAR file for ruby on rails application

Question

I am using Warbler to generate a WAR file for my ruby on rails application. I don't use anything special in my application, and i only run the "warble war" command.

In the WAR generation i am getting those 2 warnings

warning: skipping minitest
warning: skipping json

Upon the importing of the WAR in eclipse, the project can't be built and it says

Archive for required library: '/WebContent/WEB-INF/lib/gems-gems-warbler-1.4.1-spec-sample_war-some.jar'cannot be read or is not a valid ZIP file

I tried to follow some workarounds from https://github.com/jruby/warbler/issues/199 but without any clue. I am using Rails version 4.0.2 and warbler version 1.4.1 .I am new to deployment so i would be grateful if somebody can help me. Thanks

Answer 1

A better way to exclude the offending file : the warble config.

Generate the configuration with

warble config

Then uncomment the following line to fix it :

config.gem_excludes = [/^(test|spec)\//]

Answer 2

Let me warn you that this is a complete butcher job and I only used this because I was perplexed as to why I was also getting the same errors and Tomcat died when trying to deploy my jruby/rails application. Here's what I did:

$ ls -l /usr/local/opt/tomcat/libexec/webapps/workspace/WEB-INF/lib/*sample*

You will see some warbler sample jars there. gems-gems-warbler-1.4.1-spec-sample_war-some.jar has a size of 0. It's the problem, but I figure I don't really need any sample jars, thank you. So:

$ bundle show warbler
/PATH/.rvm/gems/jruby-1.7.10@rails4/gems/warbler-1.4.1

$ rm -rf /PATH/.rvm/gems/jruby-1.7.10@rails4/gems/warbler-1.4.1/spec/*sample*
$ bundle exec warble war

Deploy to Tomcat, and the context starts just fine. Less than ideal and probably there is a "correct" solution. This got me moving forward, tho.
