I put this in each subproject's maven.xml:
<ant:property file="${basedir}/../project.properties"/>
<util:available file="${basedir}/../build.properties">
<util:properties file="${basedir}/../build.properties" trim="true" />
</util:available>
I'm trying to force this order of precedence (from the subproject's
viewpoint) when defining properties:
1. ../build.properties
2. project.properties
3. ../project.properties
>From what I can tell the subproject project.properties gets loaded
before the subproject maven.xml. I load the master project.properties
using Ant so as not to override anything defined in the subproject's
project.properties. I then load the master build.properties using
Jelly, because I want properties defined there to override properties
defined elsewhere. You could also load user-specific properties last
using Jelly to give them the highest priority.
When Maven supports property inheritence, I don't know if it will do
so in this order, but it made sense for me.
