Properties Maven Plugin

The Properties Maven Plugin is here to make life a little easier when dealing with properties. It provides goals to read and write properties from and to files, and also to set system properties.

It's main use-case is loading properties from files instead of declaring them in pom.xml, something that comes in handy when dealing with different environments.

If you have a properties file called teams.properties with this content:

  toronto=raptors
  miami=heat

and invoke the properties:read-project-properties goal, it would be the same as declaring the following in your pom.xml:

  <properties>
    <toronto>raptors</toronto>
    <miami>heat</miami>
  </properties>

The properties loaded from files can be used to filter resources differently for different environments. Those using Spring's PropertyPlaceholderConfigurer can see how these goals can be useful.
