This means that all components which group is `com.mycompany` will automatically be trusted.
Trusted means that Gradle will not perform any verification whatsoever.

The `trust` element accepts those attributes:

- `group`, the group of the artifact to trust
- `name`, the name of the artifact to trust
- `version`, the version of the artifact to trust
- `file`, the name of the artifact _file_ to trust

One other thing to note is that properties like `source` have corresponding methods in core Gradle tasks.
Those methods follow the convention of _appending_ to collections of values rather than replacing them.
Again, this method accepts any of the types supported by the <<#sec:file_collections,files()>> method, as shown here:
