IntelliJ IDEA

IntelliJ IDEA is an integrated development environment (IDE) written in Java for developing computer software. It is developed by JetBrains (formerly known as IntelliJ), and is available as an Apache 2 Licensed community edition,[4] and in a proprietary commercial edition. Both can be used for commercial development.[5]

The first version of IntelliJ IDEA was released in January 2001, and was one of the first available Java IDEs with advanced code navigation and code refactoring capabilities integrated.[6][7]

In a 2010 InfoWorld report, IntelliJ received the highest test center score out of the four top Java programming tools: Eclipse, IntelliJ IDEA, NetBeans and JDeveloper.[8]

In December 2014, Google announced version 1.0 of Android Studio, an open-source IDE for Android apps, based on the open source community edition of IntelliJ IDEA.[9] Other development environments based on IntelliJ's framework include AppCode, CLion, DataGrip, GoLand, PhpStorm, PyCharm, Rider, RubyMine, WebStorm, and MPS.[10]

Coding assistance

The IDE provides certain features[14] like code completion by analyzing the context, code navigation which allows jumping to a class or declaration in the code directly, code refactoring, linting and options to fix inconsistencies via suggestions.

Built in tools and integration

The IDE provides[14] integration with build/packaging tools like grunt, bower, gradle, and SBT. It supports version control systems like Git, Mercurial, Perforce, and SVN. Databases like Microsoft SQL Server, Oracle, PostgreSQL, SQLite and MySQL can be accessed directly from the IDE in the Ultimate edition, through an embedded version of DataGrip.

Plugin ecosystem

IntelliJ supports plugins through which one can add additional functionality to the IDE. Plugins can be downloaded and installed either from IntelliJ's plugin repository website or through the IDE's inbuilt plugin search and install feature. Each edition has separate plugin repositories, with both the Community and Ultimate editions totaling over 3000 plugins each as of 2019.[15]

Supported languages

The Community and Ultimate editions differ in their support for various programming languages as shown in the following table.[16] Supported in both Community and Ultimate Edition:

There was a free plugin from Atlassian for IntelliJ available to integrate with JIRA,[29] Bamboo, Crucible and FishEye. However, the software called IDE-Connector was discontinued on June 1, 2015.[30]

The two editions also differ in their support[16] for software versioning and revision control systems.
