You are not passing the code/zip to the lambda with --zip-file option.

--zip-file fileb://yourJavaCode.zip

You can create the zip manually or using build tools like maven/gradle. Here is the link to learn more about packaging your java code for the lambda

Hi @Juned Ahsan your answer helped me to create a deployable zip file from the maven project, now I am able to create a function from CLI. I have 1 more question that 1)after creating the function every event is adding to that function like EC2,iot and so on... how can i ignore those? thanks Juned
