Snowpark project template

This project provides a quickstart template for a typical Snowpark project. It is a Maven project that is also configured to properly package and upload dependencies to Snowflake in order to avoid missing class errors. It demonstrates how to use an interactive session, create temporary UDFs, and create persistent UDFs.

To use this template --

Run as a Scala program

1. Copy src/resources/snowflake.conf.template to src/resources/snowflake.conf and fill in credentials
2. Run mvn scala:run to test things out
3. Modify this project to do what you need.

Run as an executable JAR

Note- the ./dependencies directory must still be present for upload to Snowflake

1. Copy src/resources/snowflake.conf.template to src/resources/snowflake.conf and fill in credentials
2. Run mvn package to generate the JAR file
3. Run java -jar target\snowpark-template-1.0-SNAPSHOT.jar to execute
4. Modify this project to do what you need.
