Subject RE: Ant 1.4.1 / JDK 1.4 beta3: '
Date Wed, 05 Dec 2001 00:01:42 GMT
I dont see anything obviously wrong with your env one minor change you might
want to consider is to place the %PATH% at the end of your PATH env
variable. Also i construct my javac tasks like so.. 
 
 <path id="lib.path">
  <pathelement path="${env.CLASSPATH}" />
  <pathelement path="${env.LOCALCLASSPATH}" />
  <pathelement location="${build}" />
  <fileset dir="${build}" casesensitive="yes" >
       <include name="**/*.class"/>
  </fileset>
  <fileset dir="${ext}" casesensitive="no" >
   <include name="junit.jar" />
   <include name="ZKM.jar" />
   <include name="jdom.jar" />
   <include name="xerces.jar" />
  </fileset>
  <fileset dir="${dist.lib.path}" casesensitive="no" >
   <include name="**/*.jar"/>
  </fileset>
 </path>
 
<target .....
 
  <javac
   srcdir   = "${src}"
   destdir  = "${build}"
   includes = "**/*.java"
   excludes = "**/Test*.java"
   includeAntRuntime = "false"
   classpathref="lib.path"
  >
  </javac>
 
</target>
 
Some may call my lib.path overkill but it works great for me.. oh btw i dont
use JDK 1.4 yet so im no expert. :)

i noticed these items over at SUN..

Yes, but why doesn't the default 'modern' compiler work? I simply cannot get
any compilation to work. Not even with JDK 1.3.1! 

I'm now running everything locally (Ant, JDK, *.java and build.xml), and in
a cmd.exe (instead of my cygwin tcsh which sometimes generates path
separation issues). 


Take a look at the following and tell me if there's any check i'm
forgetting:

The javac byte-code compiler has a new -source option that enables support 
for compiling source code containing assertions. Also, default compilation 
is for -target 1.2. Previously, the default was 1.1. The compiler now 
correctly detects unreachable empty statements, 

and 


The Java virtual machines in this release include several enhancements. 


Signal-chaining facility. 
64-bit support on SolarisTM-SPARCTM platform edition. 
Error-reporting mechanism. 
New facility for logging garbage-collection events. 
The Classic virtual machine is no longer shipped as part of the Java 2 SDK.

Some more on this 'Modern compiler is not available / Cannot use classic 
compiler' problem: 


I've been trying Ant 1.4, and JDK 1.3.1_01, local installations iso having 
these reside on a SMB server: always the same problem. 
I do set JAVA_HOME properly, and setting CLASSPATH to tools.jar doesn't help

either. Building using a minimal build file still gives me the error 
message. 


If i run 'ant -debug', i do get tools.jar in 'java.class.path'. 


There must be something very basic that's wrong (some other environment in 
this machine / ...) on this Win2k machine. 


tia, 
Sebastien.

Hi, 


I'm having problems getting Ant 1.4.1 to work with JDK 1.4 beta3. 
I get the 'Cannot use classic compiler' error:

I looked this up in the archives, and it seems other people had this 
problem, but the solution was always adding tools.jar to the classpath (or 
setting up JAVA_HOME correctly). I however think these things are fine, and 
running ant in debug mode seems to confirm this:

(Note the java.class.path). This happens though:

So i don't really understand what's wrong here, unless Ant 1.4.1 has an 
issue with the Sun 1.4 beta 3 SDK? 


Any help would be appreciated! 


Sebastien.
