Create library dialog
Use this field to edit the library name.
Select the library level (global, project or module).
Add items (classes, sources, documentation, and so on) to the library.
In the dialog that opens, select the necessary files and folders. For a Java library, these may be individual class and java files, directories and archives jar and zip containing such files as well as directories with Java native libraries .dll, .so or .jnilib. For an ActionScript/Flex library, these may be raw ActionScript 3 libraries, .swc, jar and zip files, the directories containing such files, and so on.
IntelliJ IDEA will analyze the selected files and folders, and automatically assign their contents to the appropriate library categories (Classes, Sources, Documentation, Native Library Locations, and so on).
When IntelliJ IDEA cannot guess the category (for example, when you select an empty folder), a dialog will be shown, in which you will be able to specify the category yourself.
To be able to use external documentation available online, click this icon and specify the URL of the external documentation.
