How to compile is a much biggest question and probably way off topic for this list. I think you need a starter tutorial on building and packaing java; there is more than one concept at work.
you will need a compiler of the appropriate version. that source has external dependancies declared in the imports from these packages: org.apache.cassandra.io org.apache.cassandra.db org.slf4j The rest of the import are internal to Java's standard library. I think you need to master the art of building and running a jar before you can reasonably hope to be playing with cassandra triggers.
