Is it true that hook plugins can only override core JSPs, services, language keys, and Struts actions?

Hook plugins in Liferay provide a way to customize and extend the platform without modifying the core codebase directly, which ensures better maintainability and upgrade paths. While it is true that hook plugins are commonly used to override core JSPs, services, language keys, and Struts actions, they are not limited to just these elements.

Hooks can actually include a broader range of functionalities and can interact with other plugins. They are versatile enough to allow developers to override other aspects of Liferay's behavior, such as layout templates and CSS. This flexibility permits a greater degree of customization, making it possible to tailor the user experience to meet specific requirements.

The assertion that hook plugins are confined to only the mentioned components is therefore incorrect. This indicates a misunderstanding of the broader capabilities of hooks in the Liferay architecture, thus confirming that the statement is false.
