You can optionally point your build properties in a configuration file:
<project>
...
<build>
...
<plugins>
<plugin>
<groupId>net.sourceforge.clownfish.mojo.glassfish</groupId>
<artifactId>clownfish-maven-plugin</artifactId>
<version>0.1.1-SNAPSHOT</version>
<configuration>
<configurationFile>/path/clownfish.properties</configurationFile>
</configuration>
<dependencies>
....
</dependencies>
</plugin>
</plugins>
</build>
...
</project>
where /path/clownfish.properties contains customised properties:
clownfish.deploy.dfmclassname=com.sun.enterprise.deployapi.SunDeploymentFactory
clownfish.deploy.uri=deployer:Sun:AppServer::localhost:4848
clownfish.username=admin
clownfish.password=adminadmin
clownfish.targets=server
clownfish.artifactTypes=ear, war, ejb, rar, car
clownfish.autostart=true
clownfish.verbose=false
