SCS_pom_xml_properties.txt

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>1.8</java.version>
        <spring-cloud-services.version>1.6.0.RELEASE</spring-cloud-services.version>
        <spring-cloud.version>Edgware.SR2</spring-cloud.version>
    </properties>

I defined a new property, spring-cloud-services.version to simplify longer-term maintenance.
