Subject javac Task Using Jikes with Large Number of Files
Date Fri, 14 Jul 2000 01:13:42 GMT
I'm trying to compile a source tree with the javac task.  I have
set  build.compiler=jikes.  The target XML looks like this:

<target name="build_java" depends="init">
   <mkdir dir="${escrow.classes}"/>
   <javac
       srcdir="${escrow.source}"
       destdir="${escrow.classes}"
       includes="com/escrow/**"
       classpath="${build.classpath}"
       debug="on"
   />
</target>

The resulting set of files number 402 source files.  When I run
the build, I get (sorry for the long wrapped lines, but that's
what comes out):

BUILD FAILED

I suspect I'm overloading the command line with too much stuff once
all 402 source file names are added.  I can run fine with about 200
source files, but not 400.  Using the JDK compiler works fine with
402 source files, but it's much slower than Jikes.

Is there something I'm doing wrong?  Should I leave off the includes
attribute (I think it's redundant since srcdir point there anyway)?
How can I get less added to the Jikes command line?

I notice I've got double entries in the classpath, probably because
they are in my environment classpath and I feed them in via the
classpath= attribute.  I want to make sure the build uses the correct
classpath, so I want it specified in the build file.  But I need some
classpath just to run ant, and there is a fair amount of duplication.
How do I get round the duplicate classpath entries?

Thanks in advance for any tips, pointers, or ideas.
