The build.gradle file isn't useful outside of gordon

Both the gradle command line tool and IDEs should be able to work with it, but it references target which must be something include outside of the file.

```
$ gradle build

FAILURE: Build failed with an exception.

* Where:
Build file '/Users/sam/Projects/gordon/nfstest/connect/build.gradle' line: 22

* What went wrong:
A problem occurred evaluating root project 'connect'.
> Could not find property 'target' on task ':buildLambda'.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

Total time: 3.978 secs
```

Start with connect/build.gradle, especially the target reference reported at line 22, then run the shown gradle build command outside Gordon's usual context. Done means the build file evaluates successfully for both the Gradle command-line tool and IDEs without requiring an external target definition.
