IntelliJ IDEA 15 Released, Adds Kotlin to the Family of Supported JVM Languages
Great news from the JetBrains team: today we’re announcing the release of IntelliJ IDEA 15!
As always, the new IntelliJ IDEA release brings a rich set of new features, better user interface, more built-in tools and integrations, and further improved coding assistance that is consistent across the entire range of supported languages and frameworks.
In other great news, Kotlin, the JVM language that JetBrains is crafting, goes Beta. Now is a very good time to try it out for productivity, conciseness and perfect Java interoperability. IntelliJ IDEA 15 bundles the Kotlin plugin and provides support for Kotlin out of the box. To get started with Kotlin, use this handy tutorial.
Both IntelliJ IDEA Ultimate and IntelliJ IDEA Community are now available for download. Also, starting today, IntelliJ IDEA 15 is available as part of JetBrains Toolbox, with new subscription licensing and pricing.
For more details on the new features and licensing, please read below.
To fully embrace Java 8 we’ve equipped our debugger with first-class lambda support: now you can precisely target lambdas when setting breakpoints, running code to cursor or an arbitrary expression, and stepping into code at the caret.
The new Force return action lets you interrupt method execution and return any specific value that you request, letting you flexibly vary the method execution logic while debugging.
On-the-fly code duplicates detection
Thanks to its enhanced code indexing engine, IntelliJ IDEA can now detect code duplicates as you type, displaying a popup that lets you examine them on the fly. To avoid pestering you, it is set by default to only detect duplicates longer than five lines of code, however you can configure this setting, or disable the inspection altogether by pressing Alt+Enter.
Spend less time switching between the dialog and the results tool window. As another perk of the improved indexing, the Find in Path action now offers an instant preview of search results as you type in the search box.
The gutter is more interactive and now allows running applications and tests. Also, new icons let you easily distinguish between failed and successful tests.
The entire test runner tool window has been redone from scratch to provide a unified interface for all languages, complete with inline statistics, vertical layout, test result history, and export/import actions.
Now every Run Configuration has a small green indicator that tells you if it’s running. If your Run Configuration is a Single instance only, the IDE will show you the Restart action instead of the Run action on the toolbar.
With the new adjustments for the red-green color deficiency, the IDE has become friendlier for people with color blindness.
We’ve also made it possible to hide unnecessary tool windows without disabling corresponding plugins.
Last, but not the least is complete HiDPI support for Windows and Linux, with fractional scaling for both fonts and icons according to your system DPI settings.
The built-in integrations with Git, Mercurial, Perforce and other version control systems have now been updated.
The Rebase action is now available from the Branches menu, and like Merge, inherits support for synchronous multi-root branch operations, automatic stash/unstash changes, and conflict resolution assistance.
The Branches menu is now available from the Log viewer context menu.
When you click the gutter, IntelliJ IDEA will highlight changes by word.
For whitespace-only changes, the gutter now uses a different color, making it easier to distinguish actual changes in the code from simple reformatting.
The option VCS changed only text, added earlier to the Reformat action has become smarter: it reformats not only the changed lines, but also the surrounding code when it makes sense.
The Undo action is now available when merging and/or resolving conflicts, and the Annotate action is available from the Diff viewer.
If you’re using Mercurial Queues, you’re welcome to check out the new tools for managing patches.
Perforce users can now shelve local changes in their Perforce repos. This option may be safer and more convenient than local shelving in certain cases.
When committing changes, TFS users will now be able to access their saved queries, and browse work item trees.
Coding assistance for Spring has been updated to support the new 4.2 features: @Bean on Java 8 default methods, @Import with regular component classes, code completion and navigation for @EventListener, @AliasFor and @ContextConfiguration support along with supporting Hibernate 5.0.
For Spring Boot users we’ve prepared a better coding assistance in application.yml and additional-spring-configuration-metadata.json files, as well as automatic Spring facet configuration based on annotations.
Grails developers will enjoy the long-awaited support for Grails 3.x, the newest version of their favorite Groovy-based web framework.
For Arquillian, we’ve made it possible to configure containers on the IDE level, and then run tests against those selected.
The Scala plugin has been updated with support for SAM (single abstract method), an intention to expand macros, Postfix completion, the Inline refactoring for type aliases, and support for dynamically named tests (e.g. “
test(variable)” or “
While working on improving Kotlin and Scala support, we didn’t forget about Groovy: meet the @Builder AST transformation support.
Front-end web developers will be glad to know that we support TypeScript 1.5 and 1.6 along with the TSLint integration, better coding assistance for React and JSX, and initial support for AngularJS 2.
The newest features in Android Studio 1.3 are now available in IntelliJ IDEA 15: Android Memory (HPROF) Viewer, and the Allocation Tracker. Changes from Android Studio 1.4 are expected in minor IntelliJ IDEA 15 updates.
It’s no secret that JetBrains is working on a brand new IDE for working with SQL code and databases, currently dubbed 0xDBE. IntelliJ IDEA, being our flagship product, includes all of that functionality. Here’s just a glimpse at the list of features to come:
- Fast and accurate schema introspection
- Modify table action
- Generating CREATE TABLE and INSERT statements via Alt + Ins (⌘ + N for OS X)
- Multiple query consoles
- Query console local history
- Execution plan
- Compare query results
- And many more…
