The following command runs the `test` task for all subprojects when invoked from the _root project directory_:

----
$ gradle test

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:

The go command and the tools it invokes consult environment variables
for configuration. If an environment variable is unset or empty, the go
command uses a sensible default setting. To see the effective setting of
