You can a pom file for a particular project like this:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<parent>
<groupId>com.soebes.smpp</groupId>
<artifactId>smpp</artifactId>
<version>2.3.0</version>
</parent>
<groupId>com.soebes.examples.j2ee</groupId>
<artifactId>parent</artifactId>
<version>3.4.6-SNAPSHOT</version>
<packaging>jar</packaging>
You can put the needed plugin configuration into the given parent. Like this example.
Apart from that you don't need to define the plugins in the build section only via pluginManagement where you define the configuration and the version of the appropriate plugins. Which can be seen here as an example.
