Packaging java dependencies for deployment

I am developing a simpla lambda function in Java and deploy using serverless. I have a plugin dependency for aws-alerts plugin. Everything works in node and I can download the dependencies using npm.

What is the corresponding dependency configuration for Java for this plugin ( I guess it should be in the maven pom file). Now I am getting the below error -

Error: Cannot find module 'serverless-plugin-aws-alerts’
at Function.Module._resolveFilename (module.js:325:15)
at Function.Module._load (module.js:276:25)
at Module.require (module.js:353:17)
at require (internal/module.js:12:17)

Any thoughts ?
