cobertura-maven-plugin and cassandra-maven-plugin caused cassandra.rpcPort to be different

I've got the following configuration in my pom.xml

            </includes>
            <filtering>true</filtering>
        </testResource>
     </testResources>

and properties file have this line cassandra_host=127.0.0.1:${cassandra.rpcPort}

The code uses this property to connect to an instance of cassandra. So whenever I run mvn clean install, cassandra.rpcPort is generated twice, one when the rest is run, and one when cobertura runs. eg.

[INFO] Reserved port 60315 for cassandra.rpcPort
[INFO] Reserved port 60316 for cassandra.jmxPort
[INFO] Reserved port 60317 for cassandra.storagePort
[INFO] Reserved port 60318 for cassandra.stopPort

then when cobertura runs,

[INFO] Reserved port 60319 for cassandra.rpcPort
[INFO] Reserved port 60320 for cassandra.jmxPort
[INFO] Reserved port 60321 for cassandra.storagePort
[INFO] Reserved port 60322 for cassandra.stopPort

And it the cassandra-maven-plugin generates a target/cassandra/conf/cassandra.yaml file which has rpc_port: 60315 (the origin port and not the one from cobertura). However the property file has the value of the port generated by cobertura.

If I disabled cobertura plugin, then everything runs successfully. Anyone know how to get around this issue?

Thanks & regards Tin

OK, I've solved the issue by moving the build-helper-maven-plugin to prepare-package phase, and add the following

<plugin>
                <artifactId>maven-resources-plugin</artifactId>
                <version>2.7</version>
                <executions>
                    <execution>
                        <id>copy-test-resources</id>
                        <phase>pre-integration-test</phase>
                        <goals>
                            <goal>copy-resources</goal>
                        </goals>
                        <configuration>
                            <outputDirectory>${project.build.testOutputDirectory}</outputDirectory>
                            <resources>
                                <resource>
                                    <directory>${project.basedir}/src/test/resources</directory>
                                    <includes>
                                        <include>*.properties</include>
                                    </includes>
                                    <filtering>true</filtering>
                                </resource>
                            </resources>
                        </configuration>
                    </execution>
                </executions>
            </plugin>

This way, cobertura plugin is already done and the network ports are only scanned/reserved once. Hope this might help someone in the future.
