Overview

At the Bolsena hacking event 2009, we decided to move from ant build to maven.

Maven structure

First changes was to identify main modules and clean dependencies to not to have cyclic references between them. To fix cyclic references, minor refactoring was made (trying to not to change too much the current code base).

Before

After

GeoNetwork is divided in the following modules :

Major changes

• GeoServer : no more embedded in GeoNetwork (should be a dependency).
• CSW client : removed
• Jetty : removed and start the web application using Maven related plugins (see Run the application)
• Installer :
  • assembly plugin is used to create a ZIP package with licence and war files
  • TODO : create a binary version with Jetty ? installer ?
• OAI-PMH dependencies
  • Duplicate iso date class to fix cyclic reference.
• Test : removed
  • removed to fix cyclic reference with GAST.
  • Actual tests also require a Jetty embedded which has been removed (test was starting Jeeves, to run test).
  • TODO : Unit test or test against a running app could be added.
• GAST :
  • GAST was using only the application path to load both resources and libs (from WEB-INF/lib). Added a libPath and an appPath.
  • Remove jetty and mckoi startup and init (see Open issues)
  • Current status : GAST could be used to create db (not mckoi ones) and load data once the catalogue is started.

Maven build

Build the application

mvn clean install

Packaging the application

GeoNetwork is distributed as WAR files (intermap.war and geonetwork.war) packaged by maven process. Assembly plugin is used to create a ZIP file with 2 required WAR files.

mvn assembly:assembly

Assembly configuration is in release package.

Run the application

Maven plugins for Jetty or Cargo allows to quickly start the application after build.

War files

Publish war files created by maven to your favorite webapp directory (Tomcat, Jetty).

Maven plugin / Cargo

Cargo looks to be the best option to run the application (easily start more than one webapp).

See : ​http://cargo.codehaus.org/

mvn cargo:start
mvn cargo:stop

Maven plugin / Jetty

mvn jetty:run

Current issue with jetty plugin is that we cannot run more than one application at a time (only geonetwork.war is started, not intermap.war).

Deploy the application

Deploy mechanism has been setup and tested with an scp connection to a remote server. We need to define where to create GeoNetwork repositories.

maven deploy

Create an eclipse workspace

mvn eclipse:eclipse

Open issues

• GAST :
  • FIXME / hardcoded classpath in MANIFEST
  • What to do with GAST and embedded jetty and mckoi ?

Proposal Type

• Type: Architecture
• App: GeoNetwork
• Module: All
