Fabric8 Components Agent/APMAgent

In the components pom there is

    <module>fabric8-agent</module>
    <module>fabric8-apm</module>

Normally, Maven interpolation ensures the APM Agent is built before the agent module. The fabric8-agent module has:

        <dependency>
            <groupId>io.fabric8</groupId>
            <artifactId>fabric8-apm</artifactId>
            <version>${version}</version>
        </dependency>

Unfortunately it seems Maven 3.3.3 running on the internal build doesn't correctly recognise this; changing the property away from the deprecated value (https://maven.apache.org/ref/3.3.3/maven-model-builder) to

            <version>${project.version}</version>

fixed it for me.
