Javac2 ant task documentation, or help?

I've started usign IDEA 4.0's UI Designer, and find it helpful. However, like many people, I prefer to have my build process separate from my IDE. I've found a few pre-4.0-release postings discussing the '' Ant task that is supposed to be a drop-in replacement for '' in order to handle the UI Designer's .form XML files, which seems like a perfect fit. However, I can't find any documentation, or get it working. I initially tried just including $IDEA_HOME/redist/javac2.jar in my compilation classpath, which gave me the following error: $ ant compile Buildfile: build.xml prepare: compile: BUILD FAILED java.lang.NoClassDefFoundError at com.intellij.util.BcelUtils$1.class$(Unknown Source) at com.intellij.util.BcelUtils.disposeBcel(Unknown Source) at com.intellij.uiDesigner.ant.Javac2.compile(Unknown Source) at org.apache.tools.ant.taskdefs.Javac.execute(Javac.java:682) ... at org.apache.tools.ant.Main.main(Main.java:235) Caused by: java.lang.ClassNotFoundException: org.apache.bcel.util.SyntheticRepository at org.apache.tools.ant.AntClassLoader.findClassInComponents(AntClassLoader.java:1075) at org.apache.tools.ant.AntClassLoader.findClass(AntClassLoader.java:1036) at org.apache.tools.ant.AntClassLoader.loadClass(AntClassLoader.java:925) at java.lang.ClassLoader.loadClass(ClassLoader.java:235) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:302) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:219) ... 12 more So, following someone else's forum post, I started including other jarfiles as well (bcel.jar, idea.jar, etc etc). I quickly tired of the guess & check, and just included every jarfile from the IDEA 4.0 release into the classpath. Crude, I know, but what the heck. That produces a RuntimeException, as shown here: $ ant compile Buildfile: build.xml prepare: compile: BUILD FAILED java.lang.RuntimeException: java.lang.NoSuchFieldException: _repository at com.intellij.util.BcelUtils.disposeBcel(BcelUtils.java:0) at com.intellij.uiDesigner.ant.Javac2.compile(Javac2.java:43) at org.apache.tools.ant.taskdefs.Javac.execute(Javac.java:682) at org.apache.tools.ant.Task.perform(Task.java:341) ... at org.apache.tools.ant.Main.main(Main.java:235) Caused by: java.lang.NoSuchFieldException: _repository at java.lang.Class.getDeclaredField(Class.java:1208) at com.intellij.util.BcelUtils.disposeBcel(BcelUtils.java:32) ... 10 more Total time: 7 seconds ]]>

My environment:
o Mac OS X 10.3
o java version "1.4.2_03"
o IDEA 4.0

From the prior postings, this task appears to work without much effort for other folks -- is there a quirk with the Mac OS JDK? Or am I doing something incredibly stupid? Will this task be openly documented in a future release?


Many thanks, & keep up the great work,
