jruby ennui avec fauvette avortée

Question

Je suis un débutant en jruby. J'ai une application Ruby Rails - que je cours avec des rials pour courir. Maintenant, je veux créer Pouillot de guerre avec un fichier WAR, mais je reçois une erreur que je ne peux rien faire:

double loading C:/jruby-9.1.5.0/lib/ruby/gems/shared/gems/activerecord-jdbc-adapter-1.3.21/lib/arjdbc/tasks/databases.rake please delete lib/tasks/jdbc.rake if present! warble aborted! NoMethodError: undefined method 'tail' for nil:NilClass Did you mean? taint rakefile:1:in rakefile:6:in C:/Hagen/leaman/lib/tasks/warbler/warbler.rake:1:in C:/Hagen/leaman/lib/tasks/warbler/warbler.rake:2:in rakefile:1:in rakefile:6:in C:/Hagen/leaman/lib/tasks/warbler/warbler.rake:1:in C:/Hagen/leaman/lib/tasks/warbler/warbler.rake:2:in rakefile:1:in rakefile:6:in ` '

faits: Windows7 JRuby-9.1.5.0 Warbler (2.0.4)

EDIT:
Si j'appelle les éléments suivants jruby -S warble --trace Je reçois la trace suivante:
nombre incalculable de fois:
