Greetings! This article covers the new, improved method for installing Immutant, and replaces the first in the getting started series of tutorials with Immutant. This entry covers setting up a development environment and installing Immutant. This tutorial assumes you are on a *nix system. It also assumes you have Leiningen installed. If not, follow these instructions, then come back here.
Installing the lein plugin
Let's install it as a global plugin:
$ lein plugin install lein-immutant 0.3.1 Copying 3 files to /a/nice/long/tmp/path/lib Including lein-immutant-0.3.1.jar Including clojure-1.2.0.jar Including clojure-contrib-1.2.0.jar Including data.json-0.1.1.jar Including fleet-0.9.5.jar Including overlay-1.0.1.jar Including progress-1.0.1.jar Created lein-immutant-0.3.0.jar
lein immutant to see what tasks the plugin provides:
$ lein immutant Manage the deployment lifecycle of an Immutant application. Subtasks available: install Downloads and installs Immutant overlay Overlays features onto ~/.lein/immutant/current or $IMMUTANT_HOME env Displays paths to the Immutant that the plugin can find new Creates a new project skeleton initialized for Immutant init Adds a sample immutant.clj configuration file to an existing project deploy Deploys the current project to the Immutant specified by ~/.lein/immutant/current or $IMMUTANT_HOME undeploy Undeploys the current project from the Immutant specified by ~/.lein/immutant/current or $IMMUTANT_HOME run Starts up the Immutant specified by ~/.lein/immutant/current or $IMMUTANT_HOME, displaying its console output
Now we need to install an Immutant distribution. We've yet to make any official
releases, but our CI server is setup to publish an incremental build every time
we push to the git repo. The latest incremental build is always available at
http://immutant.org/builds/immutant-dist-bin.zip. The previous version of
this tutorial walked you through downloading and installing the latest incremental
manually, but with the new
install task, that's no longer necessary - the
install task will download and install the latest incremental build for you.
Let's see that in action:
$ lein immutant install Downloading http://repository-projectodd.forge.cloudbees.com/incremental/immutant/LATEST/immutant-dist-bin.zip done! Extracting /a/nice/long/tmp/path/lib/immutant-dist-bin.zip Extracted /Users/tobias/.lein/immutant/releases/immutant-1.x.incremental.51 Linking /Users/tobias/.lein/immutant/current to /Users/tobias/.lein/immutant/releases/immutant-1.x.incremental.51
Part of the install process links the most recently installed version to
~/.lein/immutant/current so the plugin can find the Immutant install without
requiring you to set
$IMMUTANT_HOME is set, it will
If you want to install a specific incremental build, specify the build number (available from our builds page) as an argument to lein:
$ lein immutant install 50
You can also have it install to a directory of your choosing (if you want the latest build, specify 'latest' as the version):
$ lein immutant install latest /some/other/path
~/.lein/immutant/current will be linked to that location.
To verify that Immutant is properly installed, let's fire it up. To do so,
lein immutant run command. This is a convenient way to start the Immutant's
JBoss server, and will run in the foreground displaying the console log.
You'll see lots of log messages that you can ignore - the
one to look for should be the last message, and will tell you the Immutant was properly
$ lein immutant run Starting Immutant via /Users/tobias/.lein/immutant/current/jboss/bin/standalone.sh ... (a plethora of log messages deleted) ... 09:18:03,709 INFO [org.jboss.as] (Controller Boot Thread) JBoss AS 7.1.0.Beta1 "Tesla" started in 2143ms - Started 149 of 211 services (61 services are passive or on-demand)
You can kill the Immutant with Ctrl-C.
If you've done all of the above, you're now ready to deploy an application. We covered that in our second tutorial.
Since Immutant is still in a pre-alpha state, none of what I said above is set in stone. If anything does change, We'll update this post to keep it accurate.
