What is Early Access Program

We at JetBrains believe that making tools for developers should greatly involve listening to developers. Our Early Access Program lets development community closely participate in discussions devoted to IntelliJ IDEA and influence development planning, from early stages onwards.
Early Access Program allows you to try pre-release versions of our software to evaluate features that will be added to the next release.

Be Careful


It is important to distinguish EAP from traditional pre-release software. Please note that the quality of EAP versions may at times be way below even usual beta standards.

  2. Hello:
    I need version of IntelliJ IDEA 12.1. On the download page, this version is not listed, where can I access it?

    I guess removed it for at old it is, but resulra the latest Vaadin plugin only works for version 12.1 of IntelliJ IDEA.


    1. Previous version can be found at Previous IntelliJ IDEA Releases. However the Vaadin plugin should work in all 14.x.x versions as well.

      1. No, no ... the latest version of Vaadin plugin is 1.5.3 and is located in

        When upgrading from IntelliJ IDEA and try to update the Vaadin plugin you just installed Version 1.2, never lets you install the 1.5.3, apparently this latest version is not compatible with version 14 of IntelliJ IDEA. Already I wrote the author of the plugin but not responding.

        This latest version of Vaadin Plugin allows you to add Add-ons in a very comfortable way.


      2. I forgot to tell that to the url that sent me not listed 12.1. Which appears 12.0.4, and I do not know if the plugin vaadin work for that version. The author of the plugin specified 12.1......
