```Python
print(user_dict)
```

teríamos um `dict` Python com:

```Python
{
    'username': 'john',
    'password': 'secret',
    'email': '******@****.***',
    'full_name': None,
}
```

#### Desembrulhando um `dict` { #unpacking-a-dict }

 * for projects that are built, hence available on the file system. One project,
 * called the <dfn>aggregator project</dfn> lists one or more <dfn>sub-projects</dfn>
 * which are relative pointers on the file system to other projects. This is done using
 * the {@code /project/subprojects/subproject} elements of the POM in the aggregator project.

        // The old broken implementation would have done:
        // var plugin = getBuild().getDelegate().getPluginsAsMap().get(pluginKey);
        // return plugin != null ? new Plugin(plugin) : null;
        // This would create a disconnected Plugin that doesn't persist changes.

 that currently we have information about a project scattered across the project.xml and the
 various properties files. What needs to be done is to encapsulate all of this in the POM.

 Typically users parameterize the use of plugins, or have custom values like ${user.name}
 for use in elements like the <developerConnection/>. It would be idea if we
