Read up on how Maven handles properties, how you can use profiles, and how the Resources Plugin does property replacement.
My standard practice is to use property references in the properties file (or XML file), such as:
Then in the POM I provide a default value for the property (the default value I use is always hte value used in production), and I tell the Resources Plugin to filter resources:
<properties> <key1.value>someValueForKey1</key1.value> </properties> <build> <resources> <resource> <directory>src/main/resources</directory> <filtering>true</filtering> </resource> </resources> </build>
I can supply a different default by providing a profile with this property in my settings.xml file:
<profiles> <profile> <id>my.settings</id> <activation> <activeByDefault>true</activeByDefault> </activation> <properties> <key1.value>myKey1Value</key1.value> </properties> </profile> </profiles>
On my PC the resulting properties file will have:
build slave the properties file will have:
I can even change the value dynamically on the command line:
mvn clean package -Dkey1.value=useThisInstead
