This tutorial will answer several questions (below) within a maven project that has several configuration files (dataset, property, persistence).
1.) How to have multiple persistence, datasource and property files depending on the profile or environment variable (xxx-dev, xxx-integr, xxx-prod)?
2.) How to execute a maven copy/rename/move in a pom?
3.) How to execute an ant if inside a maven pom?
It's best to answer this question in this simple chunk of code :-)
Some notes:
1.) We need to define a dependency to ant-contrib to be able to use the ant if tag.
2.) The copy property file will execute if property local.tomcat.home is set.
Note, using -P production will only activate that profile but will not replace any variable in the actual property file. To be able to get the actual file we need to specify -Denv=prod. Also we need to bind it to the test phase and not the install phase.
