IntelliJ IDEA 16 Public Preview

It’s been wonderful (and busy) 3 months since we announced IntelliJ IDEA 15. Exciting, because we’ve been working on new features, and busy, because we promised more frequent updates. We’re proud of what we managed to accomplish during that time, and without any further ado, we’re happy to present you the first IntelliJ IDEA 16 public preview.

If you want all the details about its new features, or get yourself a copy to try right away, visit our website. Here’s a brief overview of its most notable highlights.

IntelliJ IDEA 16 continues to improve its Java debugger. Now it lets you use Groovy expressions in Evaluate and Watch windows when debugging Java applications. Debugging multiple threads and code without debug info is now simpler. The IDE will warn if you step over code that doesn’t match the running copy.

Code editor has been extended with a number of new features: now you can shift entire statements right or left,and have an easier way of importing static members. Also, the editor now supports RTL languages (e.g. Arabic or Hebrew.)

We’ve added many new code inspections, including those that help with migrating to Java 8 method references, lambda expressions, and the Optional type. The Inline and Change Signature refactorings have also been updated to correctly process such method references.

The IntelliJ IDEA project model is finally aligned with that of Gradle and supports custom source sets by resolving dependencies between individual ones. This improvement fixes a great number of issues that have been reported by our users.

VCS integration gets a couple of new actions and slightly updated UI for the Log viewer and the Diff viewer/Merge dialog. The integration with Git now supports Git worktrees.

If you’re working with Spring, you will be happy to know that we’ve added lots of coding assistance features for Spring Boot, Spring MVC, as well as have fixed many issues related to Spring Core.

The built-in coding assistance for Thymeleaf has been updated to v3, and large number of Thymeleaf 2 related issues has also been fixed.

Kotlin’s first big 1.0 release is now bundled with IntelliJ IDEA 16.

There’s something more for other JVM languages: we have significantly improved code completion for Scala.

IntelliJ IDEA 16 brings many improvements to JavaScript, ECMAScript 6 and TypeScript, and AngularJS: code completion, refactorings, better debugger, new inspections, etc.

The Docker plugin has been improved in many ways: we’ve reworked its UI and added support for Docker Machine.

IntelliJ IDEA 16 (and the entire IntelliJ platform) are migrating to Java 8. It means plugin developers can now use Java 8 features in their code.

Last, but not the least, we’ve backported new features from Android Studio 1.5

One of the key goals of this preview is receiving your feedback, so don’t hesitate to do so either here in comments, or in our tracker. We greatly appreciate your time, and wish to thank you for all your help.

Develop with pleasure!

    Are you going to keep this beautiful bird on the logo after release of IDEA 16, or it will suffer the same fate as of the owl from IDEA 15?

    • Andrey Cheptsov says:

      February 19, 2016

      Can’t confirm yet, hopefully yes. I’ll do my best to save the bird. I like it too.

        It’s true that new opening logos are very beautiful since JetBrains rebranding ! I love them, good job guys ! 😀

          Thank you!

            Cassiopeia was lovely. Would you guys be willing to share the former splash screens as a collection like Github has the Octodex: ?

            P.S. Would it be possible to customize the boot image from a plugin? I would write one to allow the user to choose which logo he/she likes the most.

    Keep the owl:-)

    • Vojtech Krasa says:

      February 20, 2016

      Or rather bring the old owl back 🙂

    Seeing that was, again, pushed back to a later release makes me really sad.

    • Maxim Mossienko says:

      February 19, 2016

      We are working on that but the feature was not ready for version 16.

      I agree, after five years, this issue is really getting old. If there’s an inexplicably complicated technical challenge behind this, it would be nice to know some details 🙂

    Please fix the gtk theme, what’s the point if some elements are stylized in their own way by IDE.

  5. Gal says:

    February 21, 2016

    Yey for more Scala support!
    It’s amazing how much better it is than Eclipse’s.

    I see there is a version with JRE (“Linux archive with x64 Java runtime”) and a version without (“Unix archive without Java runtime”).

    I don’t recall earlier versions of intellij coming bundled with JRE. Is this something new? What is it good for?

    • Andrey Cheptsov says:

      February 22, 2016

      Yes, the patched JRE fixes a number of issues with font rendering and AWT problems, and thus provides better user experience.

      • abc says:

        March 3, 2016

        Are these JRE fixes getting upstream to Oracle?

    Hello Andrey.

    I believe there is a small mistake in the first sentence of this post. Shouldn’t it be “IDEA 16”?


    • Andrey Cheptsov says:

      February 22, 2016

      The first sentence references IntelliJ IDEA 15, the previous version. It is correct.

  8. Dana DeVice says:

    February 25, 2016

    When will there be Angular 2 support? Any time soon?

    • Andrey Cheptsov says:

      February 26, 2016

      A part of it is already there. Did you try the v16 preview? Let us know what functionality you miss.

      • OZ says:

        February 26, 2016

        All directives are highlighted as unknown attributes: [routerLink], *ngIf, *ngFor, [ngSwitch], and so on.

        • Ekaterina Prigara says:

          February 29, 2016

          Please make sure that you have library somewhere in your project, e.g. in the node_modules folder (should not be excluded then) or configured as a WebStorm JavaScript library (Preferences | Languages and Frameworks | JavaScript | Libraries).

          • OZ says:

            March 2, 2016

            If I will not exclude node_modules, it will give a lot of wrong assumptions in autocompletion. Will copy it to libraries, thank for advice. Maybe will be better to add this advice to IDE itself (both to IDEA and WebStorm).

  9. Steven Downer says:

    Any chance the clone functionality of Git in the IDE can have similar features that Pull does? Such as recursive?

    • Kirill Likhodedov says:

      February 26, 2016

      Yes, we plan to support recursive clone, but not in this release. Maybe in the next one.

    Please fix the structure view, it’s the best tool to work on huge files and it’s behavior make it unusable,
