From: CsO Date: 2007-05-08T14:55:32+09:00 Subject: Plug-in org.rubypeople.rdt.debug.ui was unable to load class Hiya, I'm following the tutorial at: http://www.oreillynet.com/pub/a/ruby/2007/04/26/ruby-on-rails-meets-eclipse.html I've got: Eclipse SDK Version: 3.2.2 Build id: M20070212-1330 ruby 1.8.6 (2007-03-13 patchlevel 0) [i386-mswin32] RDT Version 0.9.0.200704141430RC1 Basically the latest stable stuff. When I try Window->Preferences Ruby>-Installed Interpreters, I get: Plug-in org.rubypeople.rdt.debug.ui was unable to load class org.rubypeople.rdt.internal.debug.ui.preferences.RubyInterpreterPreferencePage. The other options in the Ruby subtree behave similarly. Any ideas? Thanks. -- Posted via http://www.ruby-forum.com/.
