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.

  1. The upcomming Spring Integration support sounds fantastic! We can't wait here at my company - we have a few SI projects in development already and likely more to come. :-) We hope that you soon provide an EAP for download.

  2. You are missing a 4 years old feature requested by me in the release note: IDEABKL-4889 TODOs and commit changes

  3. I'm getting 404 (not found) from and 403 (forbidden) from for build ideaIU-106.396.tar.gz

  4. EAP build is being uploaded to CDN, should be fine within hour.

  5. My idea 106.491 doesn't start with neither -XX:+UseCompressedStrings nor -XX:+UseStringCache options enabled in idea.exe.vmoptions. Why's that? java7 -b136

    With -XX:+OptimizeStringConcat it starts good.

  6. says: "Updated Ruby, Python, Scala and PHP Plugins..." but I can't get either the Ruby plugin or the Python plugin working on 10.5 RC both plugins are version incompatible with this version. Any upcoming updates?

  7. so what is going to be the 108.xx build version? is it a 10.5.x / 10.6 or even "road to 11.0" ??

    there are useful fixes within this "108.XX tag"

    1. There will be no 10.6 release. The 108 branch number is IDEA 11 development.

      1. Oh no! So i have to wait till IDEA 11 for this one:



        and for sure waiting for IDEA 12 for that one:

        IDEA-54829 ;-)

        And of course pay again for an upgrade :-(

  8. There are many issues in the version 10.5.0 and most of them are bugs, and most of them fixed in 108.xx build. Now as you are saying it will be in the next release IDEA 11 and it will not be fair if updating to this release will not be for free.

    As for myself I purchased 10.5.0 and didn't work with it because 90% of my projects will not behave correctly because of these bugs which means I Had thrown my money ....!!

    Hope the update will be for free...

    1. IntelliJ IDEA 11 will not be a free update. Note that we plan to release further 10.5.x updates, and if you could point to the specific issues you're talking about, we can evaluate the possibility of backporting fixes to 10.5.x (or it's likely that they have already been backported).

      1. Thank you for your concern,

        I am waiting for fixes all related to EJB 3.1 and/or maven, one of them which I had reported and it is currently in my mind is IDEA-71718 and it is fixed in build 108.621


        1. We'll backport the fix for IDEA-71718 to 10.5.2.

          1. There are several Spring 3.x bugs out there that would be really nice to get earlier than the 11 release

            Would it be possible to backport the following to 10.5.2?

            • IDEA-66998 Spring: support java-based container configuration (@Configuration, @Bean annotations)
            • IDEA-70023 IntelliJ 10.5 doesn't respond when editing spring xml configuration files
            • IDEA-71416 Spring bean property definition hi-lighted red although propetry exists on super -class


            1. I've forwarded your request to the responsible developer, and he'll decide whether it's feasible to backport the fixes to 10.5.2.
