IntelliJ IDEA 2018.3 Help

Networking in IntelliJ IDEA

IntelliJ IDEA requires Internet connection for a wide variety of tasks. For example:

  • Checking for IntelliJ IDEA updates

  • Code inspections that can verify external resources

  • Communication with the version control servers, task servers

  • Anonymous usage statistics

  • Resolving Maven dependencies and updating plugins

  • Using the IDEtalk plugin

Besides that, IntelliJ IDEA provides IPC for commands (for example, open files), and the built-in Web server.

Some of the communication requirements are configurable:

  • To turn off checking for updates, open the Settings | Updates page, and clear the Check for updates in channel checkbox.

  • To turn off IDEtalk plugin, open the page Settings | Plugins, and make sure that the checkbox to the left of the plugin name is cleared.

  • To use only those Maven resources that are available locally, open the page Settings| Maven, and select the checkbox Work offline

  • To disable code inspection that highlights dead links, open the Settings | Inspections page, and clear the checkbox to the left of the HTML inspection Non-existent web resources.

  • You can control the frequency of sending usage statistics, or even completely disable this function in the page Settings | Usage statistics.
