RE: javac cent exception

More digging....

Note: I have this in my gump workspace:
	  <property name="build.sysclasspath" value="first"/>
Note: I've tried first & last & I've removed the line, same deal.

I inserted a -debug into the gump generated script, I then did:

	bash -x build.sh krysalis-ruper dist

I found some interesting things. A few snippets:

1)
        <target name="debugenv">
        	    <echo message="Ant                  :   ${ant.version}"/>
                <echo message="Ant File         :       ${ant.file}"/>
                <echo message="Ant Prj          :
${ant.project.name}"/>
                <echo message="Ant Java         :
${ant.java.version}"/>
                <echo message="Ant Home         :       ${ant.home}"/>
                <echo message="Java             :       ${java.version}"/>

                <available property="javac.available"
               	classname="com.sun.tools.javac.Main"/>

        	   <echo message="Javac Available  :       ${javac.available}"/>

                <echoproperties/>

        </target>

Gives:

     [echo] Ant             : Apache Ant version 1.6alpha compiled on
January 1 2003
     [echo] Ant File         :

     [echo] Java          : 1.4.0_03
     [echo] Javac Available  : ${javac.available}

Uh oh -- the javac I need sure doesn't look available!!!!

The CLASSPATH, right before launching ant sure seem to show the right entry

Also, dumping the javac parameters I see :

     [echo] srcdir=        src/java
     [echo] destdir=

     [echo] nowarn=        off
     [echo] bootclasspath=
	...
	[echoproperties] build.compiler.bootclasspath=

Is this real, or am I viewing these "too early" before they are set ?

Anybody know how to dump pathrefs?

I am starting to wonder if this is not classpath so much as class loading.
Sadly I get no output from ant to help me determine...

regards,

Adam

P.S. For anybody curious let me know and I'll forward the whole output file.

Subject: javac cent exception


When I run centipede (from latest in CVS, on Linux, on JDK j2sdk1.4.0_03)
from Gump I get this exception. When I run from the command line I don't
have a problem.
Looking at this line of code in ANT source I see:
    private static boolean doesModernCompilerExist() {
        try {
            Class.forName("com.sun.tools.javac.Main");
            return true;
        } catch (ClassNotFoundException cnfe) {
            try {
                CompilerAdapterFactory.class.getClassLoader().loadClass(
"com.sun.tools.javac.Main" );
                return true;
            } catch (ClassNotFoundException cnfe2) {
            }
        }
        return false;
    }

So I assume com.sun.tools.javac.Main is not found.
In my gump running script I know I export this (per Nick), see:
	declare -x CLASSPATH="/usr/java/j2sdk1.4.0_03/lib/tools.jar"
and:
	jar tvf /usr/java/j2sdk1.4.0_03/lib/tools.jar | grep -i javac
shows:
	   520 Fri Nov 01 23:01:36 MST 2002 com/sun/tools/javac/Main.class
.. so I beleive it starts out in my classpath, so I can't understand. I
*used* to be able to get ant inside centipede to work inside gump, on this
configuration of OS/JDK, so am I somehow corrupting the classpath, or is it
someithing in recent cent or ?????
All suggestions appreciated.
regards,
Adam
