mvn warning - build plugins version

[srl295]

WARNING: Some problems were encountered while building the effective model for com.ibm.g11n.pipeline:gp-res-filter:jar:1.2.8-SNAPSHOT
'build.plugins.plugin.version' for org.apache.maven.plugins:maven-surefire-plugin is missing. @ line 30, column 12

The plugin is specified, but no version number. I think the usual practice is to pin this down. Can probably set this as a property in one place and inherit it.

<plugin>
                                <groupId>org.apache.maven.plugins</groupId>
                                <artifactId>maven-surefire-plugin</artifactId>
…
</plugin>
