IDEA 12 EAP

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.

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.

Release Notes

Major changes in IntelliJ Idea 12

Core features:

JDK 8 "Project Lambda" support (closures and extension methods) (work in progress)
Bytecode viewer plugin
Rearranger plugin is now bundled (work in progress)
Recent Files (Ctrl-E) popup redesigned
Breakpoints dialog redesigned
Middle matching in completion
Completion includes static methods and fields
Faster project content indexing
Native help viewer under Mac OS X
Rewritten annotation processing configuration
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
- 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
New run configuration features
- Possibility to run another configuration or external tool as "before run" action
- Possibility to forbid running multiple copies of a run configuration
New intentions and quickfixes

- Make class implement interface
- Add ternary operation to avoid NPE
- Convert array access to collection access
- Move initializer to setUp()
- Remove extra argument in method call
- Convert if statement to ternary operator
- Split 'try' statement with multiple resources
- Merge nested try statements
- Merge sequential method calls into call chain
- Make package-local, Make protected, Make private
- Push condition inside call
New inspections

- String concatenation missing whitespace
Highlighting of recursive calls with gutter icons
