Example Java webapp infrastructure for Continuous Delivery

This is an example of a Java webapp project which supports techniques for continuous delivery.

Core concepts are:

• Embedded Jetty webapp for lightweight configuration, ease of use and single self contained deployment of a single binary to any environment.
• Scripted deployment of the app which supports both push and pull deployment.

Content:

• settings.xml.example: Example settings.xml. Rename and put in ~/.m2.
• pom.xml: Parent pom for the entire project.
• database/: Contains code for generating DB schema with Liquibase.
• core/: Domain objects and Dao's.
• webapp/: Embedded Jetty webapp artifact. Contains the deployable webapp artifact.
• scripts/: Contains scripts for deploying, starting and monitoring of the webapp.
• config/: Contains config for the app and the deploy script.

Preconditions:

• CI environment (e. g. Jenkins)
• Artifact repository (e. g. Nexus)
• Database (e. g. MySQL)

Usage:

• Build it: mvn clean install
• See Readme.md in sub projects for usage of the different artifacts.

Releasing:

• mvn release:prepare -DdryRun=true -Dintegration=false
• mvn release:clean release:prepare release:perform -Dintegration=false -Dgoals=deploy

Skipping targets:

The following options are available to skip certain targets:

• -DskipTests (skip all tests)
• -Dintegration=false (skip all integration tests)
• -DskipAssembly (skip war packaging, appassembler and zip assembly)
