In this example, we add a dependency to `commons-beanutils` but exclude the transitive dependency `commons-collections`.
In our code, shown below, we only use one method from the beanutils library, `PropertyUtils.setSimpleProperty()`.
Using this method for existing setters does not require any functionality from `commons-collections` as we verified through test coverage.
