IntelliJ IDEA and Kotlin top choices for JVM developers

Snyk and Java Magazine have just announced their results of surveying more than 10 200 JVM developers.  The report shows good news for JetBrains and for our users.

Kotlin is more popular than ever! It’s overtaken Scala and Groovy to be the third most used JVM language (behind Java, of course, and Clojure).

JVM Language Use

According to this survey, IntelliJ IDEA is the most popular JVM IDE, still, but you already knew that since you’re reading this on the IntelliJ IDEA blog.


Results like these are because of you, our amazing users.  You drive us to create the best possible tools, and we love doing this for you.

IntelliJ IDEA 2018.3 EAP: GitHub pull requests and more

We are excited to announce that the upcoming IntelliJ IDEA 2018.3 will come with initial support for GitHub pull requests, along with a couple of other features worth talking about in detail.

GitHub Pull requests

Now you can view all pull requests from your GitHub repository as a list inside the IDE. They are available in the brand new GitHub Pull Requests tool window. Select Main menu | VCS | Git | View Pull Requests and view the state of a PR, current label, and assignee, if any. In the right pane, you can view the altered files and use the diff to preview the changes.

We plan to add actions such as merge, close, comment, and more in the forthcoming releases. For now, you can create a local branch from a PR via the context menu and then merge it as a regular branch. From the same context menu, you can quickly open a pull request on

IntelliJ IDEA 2018.3: Helm support

Not so long ago, IntelliJ IDEA 2018.1 Ultimate Edition introduced some initial support for Kubernetes through the brand new Kubernetes plugin. The forthcoming IntelliJ IDEA 2018.3 takes it even further and now the Kubernetes plugin gets Helm support!

In the blog post covering the first EAP build of IntelliJ IDEA 2018.3, we only briefly mentioned the availability of Helm support in the Kubernetes plugin. Now the time has come to dive into the details.

Please bear in mind that you need to install not only the Kubernetes plugin v2018.3, but also the Go template plugin. After this is done, the IDE will correctly resolve the Helm resource template files and provide you with our well-known editing support: code completion, rename refactoring, and, of course, inspections and quick-fixes.

Java Annotated Monthly – October 2018

The main news so far has been the release of Java 11.  It’s not a large release in terms of new developer functionality since Java 10, but it is the first Long Term Support Release since Java 8, so if you’ve been hanging around on Java 8, now’s the time to look at all new things that made it into Java 9, 10 and 11. Java 11 also removes things. This, like, never happens in Java.  Also noteworthy, Oracle changed its licensing and support model since Java 8. Read this month’s Annotated Monthly to find out more.

Spring and Kotlin final classes

It’s time for the next topic in the series of blogs on using Spring Framework with Kotlin support in IntelliJ IDEA.

Kotlin classes are final by default, but some Spring functionality requires classes to be open. For instance, @Configuration classes should be extendable, and methods annotated with @Transactional or @Async must also be extendable. If you don’t want to bother with it, there is the all-open plugin as well as the spring plugin for Kotlin compiler. But if you don’t like the idea of modifying Kotlin rules by compiler plugins and don’t mind an additional open modifier on your classes and methods, then IntelliJ IDEA offers an inspection that checks that all necessary classes and members are declared open:
