### Testing changes

After making changes, you can test your code in 2 ways:

1. Run tests.
- Run `./gradlew :<subproject>:quickTest` where `<subproject>` is the name of the subproject you've changed. 
- For example: `./gradlew :launcher:quickTest`.
2. Install Gradle locally and try out a change in behavior manually. 
- Install: `./gradlew install -Pgradle_installPath=/any/path`

NOTE: Some tasks selectors, like `help` or `dependencies`, will only run the task on the project they are invoked on and not on all the subprojects.

When invoking Gradle from within a subproject, the project name should be omitted:

$ cd subproject

$ gradle taskName
