Cool! Thank you. What’s about Play! 2.0 support?
WarnerJan says:
June 27, 2012
Awesome! Do you an idea (no pun intended) when v12 will be released? We are looking at upgrading from v9, so we don’t wanna be “stuck” with v11 when v12 is around the corner.

How about an updated Ruby plugin that doesn’t have the deadlocks?

WarnerJan,
IntelliJ IDEA 12 will be released before the end of 2012, most likely in late November/early December.

David,
An updated Ruby plugin for Leda will be released at a later time.

What license should I have to use this EAP ? If Idea 11 license will be enough to run it more then 30 days ?

What is the ‘Brand New Compiler Mode’? You can’t just leave it at that!

But I think it’s because I am using the latest Android SDK 🙂

Yole,

Thanks for the info. Looking forward to Idea 12 🙂

More details on Brand New Compiler Mode coming soon.
Jens R says:

Looking for improved Gradle support. More on par with the current support for Ant and Maven, when editing build.gradle files.
Brice says:

On the EAP page, the new compiler stuff is really cool : Incremental Java Compilation !

Compilation subsystem rewrite: “External make” feature
– The new make is by default off, can be enabled on a per-project basis from “Settings | Compiler | Use out-of-process build for project compilation” checkbox.
– Currently supported: incremental compilation of Java, Groovy, resource copying, UI Designer forms, Artifacts, Android, annotation processing, not-null instrumentation
– Currently NOT SUPPORTED: projects that store data in Eclipse format, Grails-specific instrumentation

Highlights:
– all compilation tasks are performed in a separate process, fully independent from IDE’s VM, no interference with AWT thread, no IDE resources consumption during build
lower memory requirements for the IDE.
– in the make process javac compiler is called in “in-process” mode via java API, hence faster java sources compilation
– java make: completely rewritten java classes dependency management for faster and more accurate search of dependent classes
– ‘automake’ mode: automatic make triggered by events from IDE’s virtual file system. If such make resulted in errors, those are highlighted in Project View and editor tabs
– faster project rebuild

@Andrey: EAP comes with license key built-in. You do not need any keys to use it.
Every EAP build is also time-limited. So, you will need to updated it to a newer one eventually.

Frostman, we are adding support for play 2.0 (IDEA-82967).
finally, we are going to support in Idea12 – drools, clouds, new spring related projects, vaadin, jee7.
Yuri Trukhin says:
June 28, 2012
Need JavaFX 2 support
Eugene Zhuravlev says:
June 28, 2012
Brice, we’ve had incremental java compilation from version 1.0.
By ‘incremental’ I mean “no need to compile whole project every time”.
Jeffrey Biles says:
June 28, 2012
+1 for an updated ruby plugin. I won’t be able to participate in preview until there is one available.
Per Lundholm says:
June 28, 2012
Brand new compiler mode – that’s sounds like a the final argument against IntelliJ has been met. I recently tried, again, migrating from Eclipse and am really annoyed when I do TDD as IntelliJ is much slower in starting a test suite.

It is so bad it actually lowers productivity as I get distracted when waiting for the “make”, “parse”, “load”, etc.

Don’t use it over current code or yours caches and local history will be lost 🙂

Hello,

Either with 4.1 or 4.0.3 Android SDK we have the following exception when trying to edit a simple app main layout:

Will you be supporting the Play Framework 2.0 (for both Java and Scala)?
yakk says:
June 29, 2012
I see a note on purchase on buy&upgrade page
“any IntelliJ IDEA 10 license purchased after November 07, 2011, qualifies for a free upgrade to IntelliJ IDEA 11.”
I wonder if you are going to offer free upgrade of 11 to 12 before the release? I am considering to buy a personel licence
Christian says:

I’m hoping for Play 2 support too. Play 1.2 is in legacy mode now.
Brice says:
June 29, 2012
@Eugene I have the same feeling as Per Lundholm. However I confer that maven had some role to play there 🙂
Mirko says:
June 29, 2012
+1 Play Framework 2.0 support. Whats most needed is the ability to have correct interpretation of scala template files
sparkedge says:
July 2, 2012
cannot deploy on startup.i’ve submitted bugs to central youtrack.
this is a huge problem keeps me aways from trying out those great features.
Pronam says:
July 2, 2012
Great list of features.. Taking it for a spin shortly. Play 2 support welcome. Spring Hadoop support would be cool as well.
Gary Mc says:
July 10, 2012
I’m really hoping for the ability to debug javascript tests especially with JsTestDriver, but nodeunit would be great too. Nothing else matters at the moment

Hey guys,

Been expecting a lot from you since gr8conf. I must admit I am impressed with your vision 🙂 TomEE + Groovy 2.0 support ? what do people ask huh ? 🙂
Viraf Karai says:
July 30, 2012
I agree with Jens R – I am seriously looking forward to world-class support for Gradle in IDEA-12 (Leda) – along the lines of Maven. IDEA already has brilliant support for Maven, so please extend this level of support to Gradle too. I’ve had great success with Gradle for building Groovy projects and am looking forward to using it more and more. GMaven is just god-awful for Groovy and doesn’t work at all.
Benjamin Houdu says:

+1 JavaFX 2.0 support. Would be awesome. Eclipse has it and Netbeans too, so why not in Intellij ?
Ilan says:
September 14, 2012
I’d really wish idea 12 will have support for JavaFX too!
Alexandre Verri says:
October 4, 2012
It must have JavaFX 2.0.
Mark says:
October 20, 2012
Please tell me you are not omitting JavaFX2.0 support. If you are, someone has made a big mistake.

Come on guys….why replace the goose with some boring generic splash screen…… I demand the goose!
