IntelliJ IDEA | Preferences | Version Control | Ignored Files
The dialog box opens when you click the Add or Edit button in the Ignored Files dialog box
Use this dialog to configure rules that define which files and folders should be ignored by version control systems.
Files to ignore can be appointed explicitly by their names of through name patterns with wildcards. To have a directory ignored, you need to specify the full path to it relative to the project root..
Select the relevant option and fill in the text box next to it.
|Ignore specified file||In this text box, specify the name of the file to be ignored. Do one of the following:
Type the file name relative to the project root, for example, my_folder/my_subfolder1/my_subfolder2/my_file.
Click the Browse button and
select the desired file in the Select File to Ignore dialog box.
|Ignore all files under||In this text box, specify the name of the directory to be ignored. Do one of the following:
Type the directory name relative to the project root, for example, my_folder/my_subfolder1/.
Click the Browse button
and select the desired folder in the Select Directory to Ignore dialog box.
The rule is applied recursively to all the subdirectories of the specified directory. If a directory has several subdirectories and you want only one of them ignored,
specify the required directory explicitly, for example, my_folder/my_subfolder1/my_subfolder2/.
|Ignore all files matching||In this text box, specify a pattern that defines the names of files to ignore.
The rule is applied to all the directories under the project root.
Using wildcards in combination with slashes (/) to restrict the scope to a certain directory is not supported.
