Escalante 0.2.0 out now with SBT plugin!

We're pleased to announce the second official release of Escalante - version 0.2.0. We consider this release to be beta quality, and lacks some of the features and API stability that will end up in the 1.0.0 release.

What's in this release?

This second release focuses on improving support for Lift web applications within Escalante. These are the highlights:

  • Escalante-optimised Lift applications are now supported in any Lift version (as long as Maven resolution succeeds, see documentation for more info), including latest milestone Lift 2.5-M4 release.

  • The way Lift applications define metadata so that Escalante can resolve Scala/Lift dependencies has changed. Instead of the old WEB-INF/lift.xml archive, Escalante now searches for META-INF/escalante.yml file, which is a much more human readable archive thanks to the use of YAML, and a lot easier to work with from a parsing perspective. For more info, check the documentation.

  • Escalante optimised Lift applications can now select which extra Lift modules to use (i.e. mapper, jpa, record...etc) by defining them in META-INF/escalante.yml, hence reducing burden on permanent space to only those modules needed. To find out more, check the documentation.

  • A SBT plugin fully dedicated to Escalante is now available!! Version 0.1.0 is now available from JBoss Nexus repository. This plugin allows several for Escalante-optimised Lift WAR applications to be created (including generation of META-INF/escalante.yml), and it can deploy these applications to an Escalante instance (embedded, no separate process!) from the SBT console thanks to the escalante-run command. I'd like to personally thank Josh Suereth for the chat we had at Devoxx 2012 that kicked off the development of the SBT plugin, and David Pollak, Lift founder and lead, for motivating me to enable Escalante instances to be started from SBT. Thanks guys!! Check the Escalante SBT Git repo to find out out more about the Escalante SBT plugin.

  • Escalante Quickstarts have now been tagged for version 0.2.0 and the great news is Escalante Quickstarts now have SBT build files as well as the existing Maven files. So, regardless of whether you use SBT or Maven, Escalante's got you covered :). The SBT files are configured with the Escalante SBT plugin, so you can get started with the newly created Escalant SBT plugin right away!

  • A new Escalante Quickstart has been added showcasing interaction of Lift applications with JPA 2.0. Although injection of @PersistenceContext or @PersistenceUnit instances is not yet available, Lift developers wanting to run their JPA applications in Escalante are recommended that they bind the EntityManagerFactory instance to JNDI.

What's next?

This new Escalante version uses a newer base JBoss EAP version than the one you can currently access via OpenShift, so the previous instructions provided to run Escalante in OpenShift might not work as expected. Over the next few weeks we'll be working on getting Escalante 0.2.0 working on OpenShift, hopefully with a dedicated cartdridge.

On top of that, now that Escalante SBT integration is in place, we'll start looking into how to get Play applications run on top of Escalante, as well as carry on developing Escalante Lift integration adding more quickstarts...etc.
