Error running sass 3.4.7 on Windows 7 (64bit) and jruby 1.7.16.1

Trying to build Foundation for Apps with jruby 1.7.16.1 installed, and I see this error from gulp-ruby-sass:

gulp-ruby-sass: stderr: Errno::ESRCH: No such process - No such process
mtime at org/jruby/RubyFile.java:924
stylesheet_needs_update? at C:/jruby-1.7..16.1/lib/ruby/gems/shared/gems/sass-3.4.7/lib/sass/plugin/staleness_checker.rb:65
...

Downgrading to jruby 1.7.15 fixes the issue. For more info see https://github.com/zurb/foundation-apps/issues/203#issuecomment-65805631 and https://github.com/sindresorhus/gulp-ruby-sass/issues/168

Sass 3.4.9 might fix this issue? Not sure because gulp-ruby-sass (or foundation-apps?) requires sass 3.4.7.

Here’s a workaround for sass-maven-plugin.

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-resources-plugin</artifactId>
    <version>3.0.2</version>
    <executions>
        <execution>
            <id>create-css-directory</id>

            <goals>
                <goal>copy-resources</goal>
            </goals>
            <configuration>
                <outputDirectory>path/to/missing/directory</outputDirectory>

                    <resource>

                        </excludes>
                    </resource>
                </resources>
            </configuration>
        </execution>
    </executions>
</plugin>

I think we are all in agreement that this is a terrible JRuby Windows bug. But I also tend to agree with @seiyapl : Perhaps it would be worth while to create the output artifacts (and back date them) to prevent the JRuby problems from striking.
