Hi Mahesh,

I have checked. It seems the issue you have encountered is cause only in
the current development branch of the product-cep. It doesn't identify the
ML siddhi extension as an extension. ML siddhi extension works fine in the
latest release of CEP (4.1.0) [1].
Until we figure out the reason and come up with a solution, can you use the
latest CEP release for your work. It's fine to use that since you haven't
started actual development yet.

Best regards.
