The page is available when the File Watchers plugin is enabled. The plugin is not bundled with IntelliJ IDEA, but it can be installed from the JetBrains plugin repository as described in Installing, Updating and Uninstalling Repository Plugins and Enabling and Disabling Plugins.
A File Watcher is a IntelliJ IDEA system that tracks changes to your files and runs a third-party standalone application. IntelliJ IDEA provides predefined File Watcher templates for a number of such standard popular third-party tools (compilers, compressors, prettifiers, and others). You can also configure a custom File Watcher to run any other third-party tool.
File watchers have two dedicated code inspections:
- The File watcher available inspection is run in every file where a predefined File Watcher is applicable. If the project has no relevant File Watcher configured, IntelliJ IDEA suggests to add one.
- The File watcher problems inspection is invoked by a running File Watcher and highlights errors specific for it.
The page consists of two parts:
- A list of File Watchers available in the current project. To activate a File Watcher, select the check box next to it. If an error occurs while a File Watcher is running, the File Watcher is automatically disabled.
- A toolbar to manage this list.
