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

Icon

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.

    http://www.jetbrains.com/idea/buy/index.jsp currently says:

    Any IntelliJ IDEA 10 license purchased after November 07, 2011, qualifies for a free upgrade to IntelliJ IDEA 11.

    When do you plan to update this text for IntelliJ IDEA 12 ?

    Sam

    1. Andrey Cheptsov

      We are in the middle of deploying the new page at the moment.

      1. Sam Razialruh

        ok, we will wait with the order ;-)

        1. Andrey Cheptsov

          Actually you can order it now. Your key will qualify for free update to IntelliJ IDEA 12. The free upgrade program starts from today.

          1. Sam Razialruh

            the new text now says

            "Personal IntelliJ IDEA 11 licenses purchased after November 07, 2012, qualify for a free upgrade to IntelliJ IDEA 12."

            So it's not for commercial licenses.

            back to: "ok, we will wait with the order ;)"

            1. Andrey Cheptsov

              Right, this refers only to personal licenses. Sorry for not mentioning that. We are going to announce our new program for comercial licenses too, I hope in a few days! I think it worth to wait until that.

              1. Sam Razialruh

                did it already start for comercial licenses?

  2. Wes Clark

    The Compiler settings page now has heap and VM options, which apparently overrode what I had on the Java page, leading to out of heap space errors.  This is new in 12, and bit me.

  3. Martin Westergaard Lassen

    I haven't been able to upgrade EAP through patches for a week now. I get the following line in my event log

    15.47.28 Failed to download patch file: http://download-ln.jetbrains.com/idea/IU-122.813-123.4-patch-mac.jar

    And indeed there is a 404 on that url. Does it have something to do with the new website?

    1. Dmitry Jemerov

      Unfortunately we've discovered that our patching mechanism doesn't work with code signing on Mac, so we're no longer providing upgrade patches for Mac. We'll resume the publication of patches once this problem is resolved.

      1. Martin Westergaard Lassen

        It worked a few weeks ago on the exact same setup, so what has changed? -I'm just curious.

        1. Dmitry Jemerov

          Nothing; the code signing has been broken all along.

    2. George Thiruvathukal

      I think I had the same problem - checking for updates finds the upgrade patch but after restarting it's still on the old version. You just have to throw in the towel on this revision and download the whole new EAP application and replace the old EAP version with the new one yourself in the file system. Just a simple replacement. All plugins and personal settings are in the appropriate Library folders so they'll all still be there.

    3. Ignacio González

      I have the same problem

      12:52:58 Failed to download patch file: http://download-ln.jetbrains.com/idea/IU-122.813-123.4-patch-mac.jar

      Greetings

  4. Johan Corveleyn

    It may be worth it to upgrade the included svnkit if you release another EAP (or RC). Right now (until 123.23) svnkit version r9495_v20121031_1510 is included. When looking at the changes in the svnkit repository I saw one more recent change that might be significant:

    I don't know whether that's relevant to IDEA, but it sounds like an interesting bugfix.

  5. Matthew Kennedy

    I downloaded it a couple of times, but I think the ideaIU-123.45.tar.gz is corrupt:

    % tar xvfz ~/Downloads/ideaIU-123.45.tar.gz

    The community edition and the source are fine though (ideaIC-123.45-src.tar.bz2 and ideaIC-123.45.tar.gz)

    1. Nate

      Same here -- unable to extract the unix .tar.gz archive.

  6. Grant Gochnauer

    The RC release installs but then on first launch says the license expired - even after choosing 30 day trial and thus is unusable because it quits as soon as I start it. 

    1. Mark Vedder

      See http://devnet.jetbrains.net/thread/440139 and http://youtrack.jetbrains.com/issue/IDEA-96293#comment=27-414017. The YouTrack comment has a workaround.

      1. Nate

        Doesn't seem to work... I get a dialog immediately that says my license is invalid, Close/Upgrade/Enter-Key/Eval -- but there's no way to get an evaluation license.  Also I'm using 123.63, Ultimate Edition.

        1. Dmitry Jemerov

          This will be fixed in RC3.

  7. Michael Scholz

    Past few versions have not worked for me. I've never successfully upgraded beyond 122.746

    The current problem is that all builds fail with [blah.xml (module blah)]: AIR descriptor C:\Users\me\blah\conf\blah.xml has incorrect content: Error on line 1: Content is not allowed in prolog.

    package phase I believe, not compilation. 

    1. Alexander Doroshko

      @Michael Scholz: answered in the issue tracker http://youtrack.jetbrains.com/issue/IDEA-96489

  8. Bradley M Handy

    The download link on this page is broken.  There is a "." before "download" in the path instead of a "/".  And, "download" and "idea" should be switched in the path.  ;-)

  9. Clifton Craig

    The update button from the official IntelliJ Idea product is taking me to this EAP page. Are you now promoting EAP releases as official releases or was this a fluke? I usually don't take EAP releases unless I want to explore some early new features but this latest release fixes a minor bug in Android facets and I'm wondering if it's safe to use in production. What's the deal?

    1. Dmitry Jemerov

      Clifton,
      If you ran an EAP build once, the update checker will switch to notifying you about all EAP releases. You can switch it back under Settings | Updates.

      Note that EAP builds of major release bugfix updates normally contain no new functionality and few risky changes, so they should be OK to use in production.

      1. P.S. Heijnen

        Very true, maybe you should update the section at the top of all (previous) major release pages to reflect this:

        "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." I guess you can remove this according to your statement.

        Also, for example, on the IEA 11 page it says: "IntelliJ IDEA 11 (aka Nika) is next major version for IntelliJ IDEA." Which  is not true anymore, of course.

        However, it actually doesn't matter to me...

      2. Clifton Craig

        Thanx Dmitry!

        Yes the statement at the top had me nervous:

        "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."

        Also, I had some bad experiences from EAPs back in the 4.x 5.x days which turned me away from using them in production. However I've heard that quality has improved significantly So maybe I might give it a go one day. Thanks again!

    Is there a way to report duplicated issues ? :S

    I was going to submit an usability/ux related issued, but actually there are two reports for the same problem and are assigned to different people xD

      thanks for reading and linking issues... now is just time to wait for it xD

    IntelliJ 123.123 JDK6_u37 Win8 

    1. Alexander Heusingfeld

      Seems like it has nothing to do with the OS. The patch file for version 123.123 is simply not available. There is a file available for version 123.116 though (see http://download-ln.jetbrains.com/idea/IU-123.116-123.139-patch-win.jar)

      1. Maxim Mossienko

        The patch from IntelliJ IDEA 12.0.2 (123.123) is being uploaded right now and should be available within minutes. Sorry for inconvenience.

  13. Ted Young

    Failed to apply patch from 123.123 to 123.139:

    I ran process explorer and didn't see any other process holding onto that file.

    ;ted

    1. Oleg Aleshko

      yeah i get the same exception

      however i can see idea.exe is still running, which seems suspicious 

  14. Eugene Platonov

    This last "RC" is the worst eap version I've had. It constantly hangs up every 2-3 hours consuming all the cpu.

  15. Oleg Aleshko

    patch http://download-ln.jetbrains.com/idea/IU-123.165-123.168-patch-win.jar is unavailable again..

      We removed EAP download / patches as 12.0.4 is available
