Change inspection severity

Last modified: 11 January 2023

Inspection severity levels indicate how seriously the detected code problems affect your project. In IntelliJ IDEA, there is a set of predefined severity levels:

  • Error Error icon: syntax errors.

  • Warning Warning icon: code fragments that might produce bugs or require enhancement.

  • Weak Warning Weak Warning icon: code fragments that can be improved or optimized (redundant code, duplicated code fragments, and so on).

  • Server Problem Server problem icon: problems that come from an external build server, for example, from TeamCity.

  • Grammar Error the Typo icon: grammar mistakes. This severity comes from the bundled Grazie plugin.

  • Typo the Typo icon: spelling mistakes and typos.

  • Consideration: code fragments that can be improved. This severity is not marked on the error stripe and does not have a default highlighting style, but you can choose one from the list of existing styles or configure your own.

  • No highlighting (fix available): provides no code highlighting; the list of available fixes is invoked by pressing AltEnter.

For every severity, you can configure its own highlighting style in the editor.

Severity levels are designed to indicate problems, they don't have any impact on the code execution: if you change the severity for spelling mistakes from Typo to Error, this won't affect the execution of your application.
