Setting pom properties from Maven Plugin for resource filtering - maven

Question

I have a conf file in a java app that contains an IP address parameter. I want to be able to put in this parameter the local ip address automatically at build time. I used maven resources-plugin as follows:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>2.5</version>
<executions>
<execution>
<id>copy-resources</id>
<phase>validate</phase>
<goals>
<goal>copy-resources</goal>
</goals>
<configuration>
<outputDirectory>/home/user/config</outputDirectory>
<resources>
<resource>
<directory>config</directory>
<filtering>true</filtering>
<includes>
<include>**/*.xml</include>
<include>**/*.properties</include>
</includes>
</resource>
</resources>
</configuration>
</execution>
</executions>
Next, I've created a property that contains the parameter
<properties>
<gateway.ip>${local.ip}</gateway.ip>
</properties>
Then, I've created a Maven plugin that gets the local ip address and sets the above parameter:
final Properties props = mavenProject.getProperties();
props.put("local.ip", resultAddress.getHostAddress());
lastly, I define my custom plugin in the pom.xml:
<plugin>
<groupId>com.company</groupId>
<artifactId>get-local-ip-plugin</artifactId>
<version>0.0.1-SNAPSHOT</version>
<executions>
<execution>
<id>get-local-ip</id>
<phase>validate</phase>
<goals>
<goal>get-local-ip</goal>
</goals>
<configuration>
<localIp>${local.ip}</localIp>
</configuration>
</execution>
</executions>
</plugin>
The problem is that this doesn't work and I get ${local.ip} in the resulting file instead of xxx.xxx.xxx.xxx ip address.
Any suggestions?

found my bug :) - I bound both plugins to the validate phase (the good
