Adding support for frameworks and technologies
- Adding support for a framework
- Specifying framework settings
- Adding support for auto-detected frameworks
- Excluding frameworks from auto-detection
You can extend capabilities of a module by adding support for various development frameworks, technologies and languages. (Hereafter, the word frameworks is used to refer also to the technologies and languages.) As a result, depending on the framework, IntelliJ IDEA may:
- Download the framework implementation files, arrange those files in a library, and add that library to the dependencies of the module.
- Create a sample class or application as well as framework configuration and application deployment descriptor files.
- Add framework-specific coding assistance features to the editor.
- Create a facet for specifying how the framework is used in the module.
- Create a run/debug configuration for your application.
- Create an artifact configuration, e.g. for packaging or deploying your app.
- Provide a framework-specific tool window.
Some frameworks need to be configured. For such frameworks, IntelliJ IDEA provide facets.
A facet is part of the UI that lets you specify framework-specific settings for a module.
Usually, facets have the same names as the corresponding frameworks. For example, a facet for the Spring framework would be called a Spring facet.
Adding support for a framework
You can add support for a framework:
- When creating a project or module ( or ). On the first page of the New Project or the New Module wizard, the frameworks are shown as options under Additional Libraries and Frameworks.
For an existing module:
- In the Project tool window (): right-click the module folder and select Add Framework Support. Then select the framework(s) in the Add Frameworks Support dialog.
- In the Project Structure dialog (): select Modules or Facets and click .
Specifying framework settings
To specify the settings for an enabled configurable framework (one that has a facet), open the Project Structure dialog, select Modules or Facets, and then select the framework (the facet).
- Modules. In this section, facets are shown as module elements.
In this section,
facets that pertain to the same framework appear as elements of that framework.
For certain facet types (frameworks) there may be default settings and also the settings that can be applied to all facets of a type at once. To check if there are such settings for a framework, select the framework (i.e. the facet group name).
In this section you can also configure framework auto-detection (see Excluding frameworks from auto-detection).
Adding support for auto-detected frameworks
IntelliJ IDEA can guess that you are using a framework. If it finds a file or a directory typical of a certain framework (the corresponding checks are performed when you reopen your project), you get a notification looking similar to this:
Once you have enabled an auto-detected framework, look at the framework settings (if available) and make the necessary adjustments.
Excluding frameworks from auto-detection
By default, auto-detection is enabled for all the supported frameworks. If necessary, you can disable framework auto-detection completely or exclude individual frameworks from auto-detection. The exclusion can be project-wide or limited to a certain directory.
