What’s new in IntelliJ IDEA 2018.3 EAP 5?

Another IntelliJ IDEA 2018.3 EAP with more new goodies is now available for download! Let’s review what is inside the fresh EAP build!


For a start, the upcoming IntelliJ IDEA 2018.3 updates Git multi-repository projects significantly faster than before. Previously, the IDE could only fetch repositories one by one. Now, the IDE fetches all git repositories in the project in parallel during the project update.

As you know, in IntelliJ IDEA it is possible to view diff of the latest commit that touched a particular line – by calling Show Diff from Annotation context menu. Now, it is possible to get to the menu using keyboard only – invoke the VCS Operations pop-up (Ctrl-V on macOS /Alt+` on Windows and Linux) and choose Annotated Line | Show Diff, or whatever action or option you need there.


We’ve also added Diff Preview to the File History tab of the Version Control tool window.



We’ve also added a handy quick-fix to delete an unreachable switch branch that has been reported by the “Constant conditions & exceptions” inspection. By the way, if there are several unreachable branches, and you want to delete all of them at once, you can use the “Fix all ‘Constant conditions & exceptions’ problems in file” action.


Spring MVC

Spring MVC model variables work with Kotlin now.


Also, JDK has been updated to 1.8.0_152-release-1343-b3 x86_64 – the following notable fixes were integrated:

  • Rendering engine has been upgraded to Marlin 0.9.3 ( JRE-958 )
  • The critical issue with focus in some dialogs has been fixed ( JRE-973 )
  • A partial solution for supporting Hindi and Thai characters has been introduced ( JRE-928 )

Please see the release notes for a list of all changes.

Download the new EAP build from the website, or get it via Toolbox App. And don’t forget to share your feedback with us in the comments below, discussion forum, issue tracker, or on Twitter!

Happy Developing!

    One request from my side — could you mention it explicitly in a blog post once plugin version requirement (not sure how it’s called) goes from 999-SNAPSHOT to 183.*? I did try few EAP versions but without some plugins I cannot use it for real work.

    My EAP version does not offer an upgrade when I check for updates, is that a known issue?

    Would be really nice to have the Spring MVC model variables support for Groovy as well.

      1. In plugins repository [Preferences->Plugins] do the search “Scala” – there will be Scala plugin provided by JetBrains
      2. Install it and restart IDE
      3. After restart, go to [File->New->Project] – the plugin adds “Scala” templates group to the form. Choose one of them and IDE will create a new Scala-based project.
      If something goes wrong, please specify the details and versions of Intellij IDEA and the Scala plugin. Preferably, by registering a ticket at https://youtrack.jetbrains.com/issues/scl
