## Building and Testing

The most reliable way to build and test Guava is:

```shell
./mvnw clean install
```

If you want to run a single test, you'll need to pass multiple flags because
Guava is a multi-module project. For performance reasons, you may also wish to
skip generating Javadoc. For example:

```shell

			}
			continue
		}
		i := in.Value.Iter()
	readloop:
		for {
			var next simdjson.Iter
			typ, err := i.AdvanceIter(&next)
			if err != nil {
				r.err = &err
				return
			}
			switch typ {
			case simdjson.TypeNone:
				break readloop
			case simdjson.TypeRoot:
				typ, obj, err := next.Root(nil)
				if err != nil {
					r.err = &err
					return
				}
