I'm currently in the process of migrating a Jekyll blog to a new theme and am now running into issues while pushing my site to GitHub pages and running the Jekyll site with the --safe flag.
Right now, the Jekyll site runs perfectly fine locally but I started hitting issues when pushing up to GitHub pages.
As a debugging measure, I read to ensure the Jekyll site runs without issues with the --safe flag which it does not.
However, I'm not exactly sure what the issue is here. Here's my output running it with bundle exec jekyll serve --safe --trace --verbose:

Reading that trace, I understand the issue is happening here but I'm not exactly sure how to fix this? (repo link)
Any ideas?
I finally got this working but I took a different approach rather than solving the --safe flag issue.
Instead, I now have two branches. One is for normal Jekyll development locally and the other is for pushing to GitHub pages (only the _site directory).
The entire process for that is outlined here.

When I check on the website, the app is created and running, but I can't proceed to the next step of this tutorial
$ cd wildfly
$ rhc app stop --app wildfly
$ git rm diy/index.html
$ git rm diy/testrubyserver.rb
cd wildfly is not working, rhc app stop --app wildfly stops app (as it should), and another 2 commands can't find repo. I think it's because create app command should do something more, but it was interrupted by this error. Am I wrong? What can I do to stop this error from happening?
I have a writing collection in my Jekyll site, and I have output set to true, because I want all the .md and .html files rendered. However, there are some .js and .css files as well, which I'd like Jekyll to just serve up as normal.
I'm getting this error
undefined method `data' for #<Jekyll::StaticFile:0x00000104d8bb70>
and I believe it's because Jekyll is trying to parse out the js/css files.
Is it possible to have static files served up normally within my collections?

You normally should be able to use static files in collection but there is a jekyll-redirect 0.6.2 bug (ticket is here).
Workarounds
1. use Github pages configuration
If you plan to serve your site from Github pages, you will need to add a Gemfile with
source 'https://rubygems.org'
gem 'github-pages'
Then do a bundle update. This will resolve the problem as Jekyll-redirect 0.3.1 doesn't try to make redirect for collections.
2. Move your static files
Move your static files out of your collection folder to avoid the bug with collections static files.
3. Remove redirect plugin
If you don't need it or need it just for one or two pages, remove it from you Gemfile and craft needed redirect page by copying redirect pages.
I've been trying to get buildr to run checkstyle.
I've added the requirement as
require 'buildr/checkstyle'
But when I run
buildr checkstyle:html
I get this (with trace)

Any idea what I have missed?
A few things to note. The checkstyle targets are added to the project in which they are defined. So if you create a project like
require 'buildr/checkstyle'
define "foo" do
project.version = "1.0.0"
checkstyle.config_directory = _('etc/checkstyle')
end
Then you will need to invoke the buildr task "buildr foo:checkstyle:html". It should be noted that it is not enough to simply add the require to the buildfile, you also need to supply a configuration file listing the checks. By default this located in the configuration directory with a name of "checks.xml" so for the above example you would need to place the checkstyle configuration file at "etc/checkstyle/checks.xml".
Versions of buildr prior to 1.4.17 also require that you specify an xsl stylesheet if you want to generate a html report. This defaults to the name "checkstyle-report.xsl" in the configuration directory but from buildr versions 1.4.17 onwards, buildr supplies it's own version of the xsl.
On a ubuntu server, with everything installed (checked against another pc where this works just fine) When trying to run warble on one of my jruby projects, I get this error:

all libraries and required gems seem to be there.
Google didn't help, and the strange thing is that on other pc this works fine...

What version of libxml2 are you using?
I had this same problem on OSX (leopard) which ships with libxml-2.6.x. I installed libxml-2.7.3 and the error went away. More info here: http://wikihub.berkeley.edu/x/zgXNAQ
