Add code with AddJar() when using streams API?

Question

How can I use the addJar() method when I implement a stream?

The newJob() uses a DAG:

JobConfig config = new JobConfig();
config.addJar("..");
jet.newJob(dag, config).execute().get();

Streams are changed to DAGs internally:

IMap<String, Long> counts = lines
                .stream()
                .flatMap(..);

This is possible as of version 0.4

IStreamMap<Integer, Integer> map = jet.getMap(randomString());
range(0, 10).parallel().forEach(i -> map.put(i, i));

JobConfig jobConfig = new JobConfig();
jobConfig.addClass(MyMapper.class);
List<Integer> list = map
    .stream()
    .configure(jobConfig)
    .map(new MyMapper())
    .collect(toList());
