*Example 1:* Setting a project property via the *command line*:

Gradle can also set project properties when it sees specially-named system properties or environment variables.
If the environment variable name looks like `ORG_GRADLE_PROJECT___prop__=somevalue`, then Gradle will set a `prop` property on your project object, with the value of `somevalue`.

       changes with every test execution, such that running the test
       actually changes the test classpath itself. This means that it
       can"t benefit from incremental build acceleration, because on every
       execution it sees that the classpath has changed, and so to be
       safe, it needs to re-run.

       - This is unfortunate, because actually it would be safe to declare
       the task as up-to-date, because these two files, which are based on
