## Hudson Wargemmer
|
||||
|
||||
#### What?
|
||||
|
||||
The hudson wargemmer consists of two parts: a Rake task for turning a hudson war file
|
||||
(__W.__eb __A.__ __R.__chive for those not familiar with java lingo) into a distributable rubygem, and a cron task for creating
|
||||
a new version of the gem, whenever a new hudson version comes out.
|
||||
|
||||
The script polls the hudson update center and checks to see if there is a newer version of the hudson distribution that
|
||||
has not yet been gemmed up and if not, then bundles it and pushes it to [rubygems.org](http://rubygems.org) as a gem named
|
||||
hudson-war.
|
||||
|
||||
The generated gem has the same version number as the hudson distribution itself. So if you want the 1.386 distribution, then you would do a
|
||||
|
||||
gem install hudson-war --version 1.386
|
||||
|
||||
#### How?
|
||||
|
||||
In addition to the war file long with the The hudson-war gem comes with an executable script `hudson.war` to help you leverage your hudson distribution.
|
||||
|
||||
Without any arguments, it returns the location of the hudson warfile itself:
|
||||
|
||||
$ hudson.war location
|
||||
/path/to/hudson.war
|
||||
|
||||
It can unpack itself to a given directory. This is useful if you want to extract certain assets such as classfiles, annotations, configurations from it.
|
||||
|
||||
$ hudson.war unpack /tmp/hudson.war.exploded
|
||||
|
||||
It can copy itself anywhere
|
||||
|
||||
legolas: cowboyd$ hudson.war cp tmp
|
||||
copied /Users/cowboyd/.rvm/gems/ruby-1.8.7-p174@hudson.war/gems/hudson-war-1.391/lib/hudson/hudson.war -> tmp
|
||||
|
||||
Or if you want the classpath:
|
||||
|
||||
$ hudson.war classpath
|
||||
legolas:hudson.war cowboyd$ hudson.war classpath
|
||||
/Users/cowboyd/.hudson/wars/1.391/WEB-INF/lib/hudson-core-1.391.jar
