- For example: `./gradlew :launcher:quickTest`.

#### Install Gradle locally

and try out a change in behavior manually. 
- Install: `./gradlew install -Pgradle_installPath=/any/path`
- Use: `/any/path/bin/gradle taskName`.

It's also a good idea to run `./gradlew sanityCheck` before submitting your change because this will help catch code style issues.

> **NOTE:** Do **NOT** run `gradle build` on the local development environment,
