You appear to be missing a dependency for jna-3.2.4
This isn't available on the central maven repo http://repo1.maven.org/maven2/net/java/dev/jna/jna/
But you can find it in the java.net repo http://download.java.net/maven/2/net/java/dev/jna/jna/3.2.4/

Make sure that you have the java.net repo defined to your maven build.
This can be done iether in your pom, or in the settings.xml in your user home/.m2 directory.
