I agree that using ANT is no more cross-platform than using the JDK directly to compile Java code.
Enclosed is a zip of 2 classes and a manifest that I wrote that encapsulate calling the Javac compiler without java.exe. The main reason I wrote it was so it found the JDK (1.2+) tools.jar containing the Javac compiler automatically (so no need for a JAVA_HOME env. var. as ANT requires), and also for doing message filtering. By looking at the Javac.java file (ignoring the message filtering stuff), you should easily be able to call the JDK compiler from your Java code. Using the filtering of message, and passing the -verbose switch to the Java compiler, I display which classes actually get recompiled during a Javac run (including implicitly compiled classes found through the source path), and also reformatted the Javac error messages so Visual Studio could jump to the error on F4. To run from the command line (or makefile), these 2 classes are packaged in a tiny JAR that I run as below: java -jar $(JAX_DIR)\lib\JAVAC.jar -verbose [any regular Javac options] I hope you or anyelse finds this useful. --DD <<JavacShim.zip>> -----Original Message----- From: Mark Derricutt [mailto:[EMAIL PROTECTED]] Sent: Wednesday, February 13, 2002 11:42 PM To: Ant Users List; Erik Hatcher; Jay Riddell Subject: RE: Calling Ant from Java: An example please ? Hmmmm, and the lack of cross platformability is where? As long as you have tools.jar on your class path, load the load com.sun.tools.javac.Main and work with it. I've never done it myself, but I'm just looking at the JEdit JCompiler plugin code which does it, doesn't seem to hard. And I'm guessing the Ant <javac/> task code does something similiar as well... --On Wednesday, February 13, 2002 17:07:15 -0800 Jay Riddell <[EMAIL PROTECTED]> wrote: > Also, Mark asked why didn't I just call the compiler (instead of Ant)? > Because I am trying to write cross-platform code and I was planning > on using Ant as my "cross-platform compiler". -- \m/ -- "...if I seem super human I have been misunderstood."
