IntelliJ IDEA 2020.2 Help

Disabling and enabling inspections

Some inspections may report problems that you currently do not want to see. In this case, you can disable or suppress them.

When you disable an inspection, you turn it off. It means that the code analysis engine stops searching project files for the problem that this inspection is designed to detect. Note that when you disable an inspection, you disable it in the current inspection profile; it remains enabled in other profiles.

Disable inspections

Disable an inspection in the settings

  1. In the Settings/Preferences dialog Ctrl+Alt+S, select Editor | Inspections.

  2. Locate the inspection you want to disable, and clear the checkbox next to it.

  3. Apply the changes and close the dialog.

You can quickly disable a triggered inspection directly in the editor.

Disable an inspection in the editor

  1. Place the caret at the highlighted line and press Alt+Enter (or click the Intention action icon to use the intention action).

  2. Click the arrow next to the inspection you want to disable, and select Disable inspection.

Disable an inspection in the Results tool window

  1. In the Inspection Results tool window (after running code analysis), right-click the inspection you want to disable and select Disable inspection.

  2. Click the Filter resolved items icon to hide the disabled inspection alerts.

Re-enable inspections

  1. In the Settings/Preferences dialog Ctrl+Alt+S, select to Editor | Inspections.

    You can also press Ctrl+Alt+Shift+H and select Configure Inspections.

  2. Locate the disabled inspection in the list and select the checkbox next to it.

    Modified inspections are written in blue. You can also click the Filter Inspection button and select Show Only Modified Inspections to display only the inspections with changed settings.

  3. Click OK to apply the changes.

Suppress inspections

When you suppress an inspection, the code analysis engine doesn't highlight the problem found by this inspection in the specific piece of code (class, method, field, or statement). You can also suppress all inspections in the current class.

After you suppress an inspection, IntelliJ IDEA adds a new element before the selected symbol.

For example in Java, if you suppress an inspection for a class, a method, or a field, the IDE adds the @SuppressWarnings annotation. For statements, the //noinspection comment is added.

In other languages, the IDE adds other elements. For example, in PHP, IntelliJ IDEA adds the /** @noinspection */ comment. In Python, the # noinspection comment is added. In JavaScript, inspections are suppressed with the // noinspection comment.

Suppress an inspection in the editor

  1. Place the caret at the highlighted line and press Alt+Enter (or click the Intention action icon to use the intention action).

  2. Click the arrow next to the inspection you want to suppress, and select the necessary suppress action.

    Suppressing an inspection

Suppress an inspection in the Results tool window

  • In the Inspection Results tool window (after running code analysis), right-click the inspection you want to suppress and select the necessary suppress action.

Enable suppressed inspections

  • To re-enable a suppressed inspection, delete the annotation or the comment that the IDE has added before the selected symbol.

Change the highlighting level for a file

  • By default, IntelliJ IDEA highlights all detected code problems. Hover the mouse over the widget in top-right corner of the editor and select another level from the Highlight list:

    • None: turn highlighting off.

    • Syntax: highlight syntax problems only.

    • All Problems: (default) highlight syntax problems and problems found by inspections.

    Changing highlighting level for a file
  • You can also change the highlighting level from the main menu. Select Analyze | Configure Current File Analysis or press Ctrl+Alt+Shift+H .
