Joule CLI

Joule ships with a Command Line Interface (CLI) for running your Joule project. To use the CLI your workflow generally looks like this:
1.Define your use case using the Joule DSL
2.Develop custom components within an IDE and test them locally, if required
3.Define the required data sources and sinks using Joule DSL
4.Run your use case from the command line
Example
java -cp "./lib/*" com.fractalworks.streams.joule.JouleCLI \
         -s eventSource.yaml \
         -e usecase.yaml \
         -p publishSinks.yaml
Command line arguments
The CLI has a few command line arguments to run the Joule process.
Required
-s or --source for data source file
-u or --usecase for stream processing use case file
-p or --publish for event sinks file
Optional
-c or --config for custom Joule process configuration file
-r or --refdata for reference data sources file
Prerequisites

To develop components read the setting up environment document for detailed requirements.
Within the example repository, we have provided a bash script for additional functionality. Check the README.MD for further information
