Error: Could not find or load main class com.amazonaws.services.kinesis.multilang.MultiLangDaemon

I was using the `amazon_kclpy_helper.py` command to print the command to run Python KCL client so far and it stopped working approximately yesterday.

When I now create a new virtualenv and reinstall the `amazon_kclpy` it stopped working in all my environments (other working machines, build machines, etc). All the jars were correctly downloaded into the virtualenv when installing the library.

Also all the samples in that the documentation/README fail with the same error.

Examples from my vagrant development VM:

```

```

Did something change in the dependent libraries that would affect the command to fail running the KCL?

Thank you for looking into it.
