SoapUI Maven Project Properties POM not working

Update:

Finally figured it out. I moved the <configuration> tag in my pom.xml outside of the <execution> node but still within the <plugin> node like this:

<plugin>
                <groupId>com.smartbear.soapui</groupId>
		<artifactId>soapui-maven-plugin</artifactId>
		<version>5.4.0</version>
		<configuration>
			<projectFile>xxx-soapui-project.xml</projectFile>
		    <printReport>true</printReport>
		    <testFailIgnore>false</testFailIgnore>
		    <projectProperties>
			<value>jdbcUsername=xxx</value>
		    </projectProperties>
		</configuration>
		<dependencies>
                    <dependency>
			<groupId>xxx</groupId>
			<artifactId>xxx</artifactId>
			<version>xxx</version>
		    </dependency>
                </dependencies>    
                <executions>
                    <execution>
                        <goals>
                            <goal>test</goal>
                        </goals>
			<phase>test</phase>
                    </execution>
                </executions>
</plugin>

After this, everything worked.

Documentation should be updated!!! Hope this helps others.

Thanks
