-#### `azure-functions:add`
-- Create new Java function and add to current project.
-- You will be prompted to choose template and enter parameters.

 #### `azure-functions:package`
 - Scan the output directory (default is `${project.basedir}/target/classes`) and generating `function.json` for each function (method annotated with `FunctionName`) in the staging directory.
 - Copy JAR files from the build directory (default is `${project.basedir}/target/`) to the staging directory.

 Follow below instructions, you don't need to handwrite `function.json` any more.
-1. Use annotations from package `com.microsoft.azure.serverless:azure-functions-java-core` to decorate your functions. 
-2. Run `mvn package azure-functions:package`; then `function.json` files will be automatically generated for all functions in your project.
