Introduction

The list of imports suggested by IntelliJ IDEA can be sometimes far too wide, and can include the classes you don't actually need. For example, some of the class names in your project can match the names of internal SDK or unrelated library classes.

IntelliJ IDEA lets you configure the classes to be excluded from import assistance and code completion, thus helping avoid unintentional use of the wrong classes. Besides that, IntelliJ IDEA provides an intention action that allows you to exclude unnecessary classes on-the-fly.

These settings apply to code completion as well. The classes and packages specified as the ones to be ignored by the code completion feature, will not be added to the suggestion list.

Configuring imports

To configure classes to be excluded from import

1. Open the Settings/Preferences dialog box, and under the Editor / General node, click Auto-Import.
2. On the Auto-Import page, click  (Alt+Insert).
3. In the dialog box that opens, type the name of the class or a whole package to be excluded, and click OK.

   Use  (Alt+Insert) and  (Alt+Delete) to manage the list of classes and packages that IntelliJ IDEA shouldn't place to the suggestion list.

4. Apply changes and close Settings/Preferences dialog.
