I think the path you pass along is invalid. The path in Windows is expected to use backticks, F:\project\pom.xml.
jruby, trying to read this path, fails in the expand_path method. That's all I can tell at first sight (and without a Windows machine). You can try to read the JRuby source code for that method to find out more. https://github.com/jruby/jruby/blob/1.6.5.1/src/org/jruby/RubyFile.java#L1100 On Thu, Mar 8, 2012 at 09:36, Khristian <der.ko...@gmail.com> wrote: > I'm trying to read an existing Maven 2 POM file in an application I'm > developing.
