Download IntelliJ Idea 2018.3

JetBrains releases several development environments such as CLion targeting C and C++, DataGrip targeting SQL, PhpStorm targeting PHP and IntelliJ Idea targeting Java. IntelliJ Idea offers smart code completion, deep static analysis, intelligent refactorings, debugger and a test runner, and can also handle Kotlin, Groovy, Coffee and Actionscript. For an overview of the possibilities, we refer to this page† IntelliJ Idea is available in two flavors, a licensed Ultimate flavor with more functionality and a free open source Community flavor. The Ultimate flavor will require payment for business and home use, but if the software is used for education or non-commercial open source projects, the license is free. JetBrains has released IntelliJ Idea 2018.3 with the following announcement:

IntelliJ IDEA 2018.3: GitHub Pull Requests, Java 12, Multiline TODO comments, Git submodule support and More

Visit What’s new for a detailed overview, or go straight to the website and download the brand new version of IntelliJ IDEA right now. Keep reading for a brief summary.

Java

• IntelliJ IDEA supports the upcoming Java 12, and you can already preview the Raw String Literals (JEP 326) in the IDE.
• The IDE can now spot duplicates in more complicated cases, and it does this faster as well.
• Java Stream API improvements: redundant sorted calls that are made before the subsequent min call are now detected.
• A new data-flow-based inspection detects situations where the first condition is unnecessary because it’s already covered by a second condition.
• The IDE now identifies situations where a suppressed inspection no longer addresses any warnings in the associated method body, class, or statement.

Editor

• The IDE highlights the first and all subsequent TODO comment lines in the editor and displays them in the TODO tool window.
• A new indentation status bar displays the size of the indent in the current file.
• You can create a scope to disable code formatting from being done on specific files and folders. Go to the ‘Formatter Control’ tab in Preferences / Settings | Editor | Code Style.
• Syntax highlighting and code completion are now available for EditorConfig files.

• The new updated Structural Search & Replace dialog comes with loads of enhancements, including autocompletion in the search field, more flexible scope configuration, and more.

Reworked Plugin Preferences Page

• Improved Angular support: much more accurate code completion and Go to definition for variables, pipes and async pipes, and template reference variables.
• You can now debug Node.js worker threads.
• More flexibility with ESLint and TSLint.
