cleanup bc*.jars before expanding (default) jruby-openssl gem (partially fixes #1649)
bc.version no longer used - only bouncy-castle.version is
we no longer need this chunk to provide Ruby 1.8.6 (JRuby 1.4) compatibility
bouncy-castle-java gem is redundant as the bc jars are now embedded into jruby-openssl
use snapshots of ci.jruby.org/snapshots/maven for "all" profile, i.e. rake maven:dump_poms work as long there are snapshots online [skip ci]
Merge branch 'openssl-bc-jars++' of github.com:kares/jruby into kares-openssl-bc-jars++
Merge branch 'kares-openssl-bc-jars++'
Merge branch 'master' of jruby.org:jruby
use File.delete instead of FileUtils.rm_f which has problems on windows - fix #1628
