arara was recently included in TeX Live 2012, as seen in the output of
$ tlmgr info arara
shortdesc: Automation of LaTeX compilation.

Did you update your TeX Live distro recently? If not, maybe
arara is missing from the repositories. A quick
tlmgr update --self --all will ensure an update to every single package and tool available in the TL tree to their last revisions.
arara deployed in TL, open your terminal and try

usage: arara [file [--log] [--verbose] [--timeout N] [--language L] |
--help | --version]

-L,--language <arg> set the application language
-l,--log generate a log output
-t,--timeout <arg> set the execution timeout (in milliseconds)
-v,--verbose print the command output
-V,--version print the application version
TeX Live takes care of adding a symbolic link to the
arara.sh script which calls
arara.jar with the operating system's Java Virutal Machine (if I recall correctly, Ubuntu comes with at least OpenJDK, which
arara is compliant).
If you cannot get the output, maybe the TeX Live 2012
bin/ folder was not added to the path. Try running
which pdflatex in your terminal and see the full path, it should have mention to the TL2012 install. If not, you might need to include the correct folder. Of course, it depends how you installed TeX Live in the first place.
According to the user manual, go to Preferences,
then go to Typesetting path, and click the + button in the Processing tools.
Now select the path to
arara. Note that in this image, I used the path provided with the standalone installer of
arara, since you are using the TeX Live version, stick with the link available in TL's
arara is available in the Profiles list.
Hope it helps.
Update: If we are talking about the TeX Live 2012 version available through Ubuntu's own repositories and not the TL version from TUG (a.k.a vanilla),
arara is not available.
The best option, in this case, is to use the standalone installer available in the project repository. For more information on how to install
arara with the installer, I kindly suggest Chapter 2 of the manual.
