We have made a new beta version available: drjava-beta-20100415-r5220 [1]. You can download it from SourceForge [1] or from the DrJava [2] homepage.
Available for download at http://drjava.org [3] .
DrJava is a lightweight programming environment for Java designed to foster test-driven software development. It includes an intelligent program editor, an interactions pane for evaluating program text, a source level debugger, and a unit testing tool.
In addition to bug fixes in anticipation of the next stable release, this beta release includes a number of new features introduced after the last stable release:
These features include JUnit 4 support, ConcJUnit support, and the ability to use the built-in Eclipse compiler, the OpenJDK and JavaMint compilers.
Note: Java 1.4 compatibility has been dropped. To use DrJava, you will need Java 5 or newer.
New features since the last stable release:
- The Eclipse Java Compiler is now integrated into DrJava. DrJava therefore does not require the JDK anymore to compile programs. Note that the JDK is still required to use the debugger or to create Javadoc.
- DrJava supports the OpenJDK and JavaMint (multi-stage programming in Java; see http://www.javamint.org/ [4] ) compilers.
- JUnit 4.7 support.
- ConcJUnit support (for concurrent unit tests; see http://www.concutest.org/ [5] ).
- Access control for private and package private members now enabled by default.
- DynamicJava (Interpreter) error messages are much better, especially those involving method and constructor invocation.
- Added support in DynamicJava for explicit type arguments in local function invocations (“x =
foo(23)”). - The Breakpoint, Bookmarks, and Find Results tabbed panes now have Previous/Next buttons and associated keyboard shortcuts for simpler browsing.
- The Interactions Pane working directory can now be specified even when not using projects.
- If DrJava cannot start, for example because of bad memory settings in the Preferences, DrJava will suggest that you let it reset the Preferences.
- The preferred compiler can now be set, and this setting will be restored when DrJava starts the next time.
- Zoom for Print Preview.
- New Class wizard.
- Save Copy ability for Definitions documents, Interactions Pane and Console Pane contents.
