SBT: Avoiding re-creating the assembly JAR
Spark’s default build strategy is to assemble a jar including all of its dependencies. This can be cumbersome when doing iterative development. When developing locally, it is possible to create an assembly jar including all of Spark’s dependencies and then re-package only Spark itself when making changes.
When developing locally, it’s often convenient to run a single test or a few tests, rather than running the entire test suite.
Apache Spark leverages GitHub Actions that enables continuous integration and a wide range of automation. Apache Spark repository provides several GitHub Actions workflows for developers to run before creating a pull request.
