+#### IMPORTANT REMINDER FOR BELOW STEPS: When submitting a PR please make sure to NOT commit the changes mentioned in these steps, instead once testing is done make sure to revert the changes and then submit a pr.

+0. Build the project with the intended profiles via the `mvn` cli, for example for spark 3.2 use `mvn clean package -Dspark3.2 -Dscala-2.12 -DskipTests`. 
+1. Install the "Maven Helper" plugin from the Intellij IDE.
+2. Make sure IDEA uses Maven to build/run tests:
+   * You need to select the intended Maven profiles (using Maven tool pane in IDEA): select profiles you are targeting for example `spark2.4` and `scala-2.11` or `spark3.2`, `scala-2.12` etc. 
+   * Add `.mvn/maven.config` file at the root of the repo w/ the the profiles you selected in the pane: `-Dspark3.2` `-Dscala-2.12`

Review Comment:
   Can we add `.mvn` to the git ignore to help prevent people from adding it to their PRs?
