JetBrains IntelliJ IDEA Blog

Good news for those, who can’t wait IntellliJ IDEA 12 to try new features. Today we have released IntelliJ IDEA 12 EAP 122.592 with a bunch of improvements and new features.

Major changes in this release include:

• JDK 8 Method and Constructor References support.
• Glassfish 4.0 support
• SQL Dialect Intention (now it recognizes SQL dialect in files you edit).
• ActionScript Compiler 2.0 support (which brings better performance and inline features).
• ActionScript Code Arranger

The full list of changes can be found in Release Notes.

Feel free to share your feedback and report bugs in our issue tracker.

IntelliJ IDEA 12 is on the way to release and we keep working hard to make it sooner. We would also like to mention, that new project templates and SourceMap support are in the progress. This also refer to the new icons and look and feel.

So please stay tuned and let us know what you think!

Develop with Pleasure!

Today we’re beginning the Early Access Preview for the next bugfix update of IntelliJ IDEA, version 11.1.3. The new build includes fixed data flow analysis algorithm (fewer ‘Method is too complex to analyze’ warnings), better AIR applications packaging, and quite a number of other fixes. You can download the new build from the EAP page or update from the IDE using “Check for updates”.

If you’re an IntelliJ user working under Linux you’ve probably seen that boring “Synchronizing files…” spinning icon in a left corner of a status bar. It is there because for an intelligent IDE it is a must to be in the know about any external changes in files it working with - e.g. changes made by VCS, or build tools, or code generators etc. On Windows and Mac OS X native file system watchers used to facilitate this task but on Linux the only option was to recursively scan directory tree. Now you’re welcome to give a try to native file system watcher for Linux.

Prerequisites

File system watcher requires inotify(7) facility. It is in mainstream kernel for more than two years (since 2.6.13, and in glibc since 2.4) so chances are your distribution don’t missing it. The sign of inotify availability in a system is a presence of /proc/sys/fs/inotify/ directory.

Download and setup

File system watcher is a single binary executable (fsnotifier) and can be downloaded directly from our Git repository. It should be named ‘fsnotifier’, placed into bin/ directory of your IDE and granted execution rights. Inotify requires a “watch handle” to be set for each directory it monitors. Unfortunately, the default limit of watch handles may not be enough for reasonably sized projects (e.g. IntelliJ IDEA sources contain 30000+ directories). The current limit can be verified by executing:

cat /proc/sys/fs/inotify/max_user_watches

It can be raised by adding following line to the /etc/sysctl.conf file:

fs.inotify.max_user_watches = 524288

… and issuing this command to apply the change:

sudo sysctl -p

64-bit systems

If your system is strictly 64-bit (i.e. doesn’t contains 32-bit runtime libraries in /lib32 directory) you should download 64-bit version here. Rename downloaded file to “fsnotifier”, rest of setup is same.
