Are you sure that there is not another JAVA_HOME environment variable
defined; maybe like a system-level one? Or maybe something else weird
in your PATH variable?

A little background first.
I've been using Maven even before the 1.0 release, and have been
very happy
with it. I've created very complex builds and have a very good working
knowledge of Maven 1.x. The structure I describe below, is
precisely how
I've successfully built projects with Maven 1.x countless times.
I'm starting a whole new project, and would like to see if Maven 2
is going
to be something I want to use.
Now on to my problem. Maven 2 cannot find the Javac Compiler that I
believe
I pointed it to.
I'm running the latest Maven download, version 2.0, on Windows XP
I've created two project modules :
csi_build
csi_common
csi_common contains my first simple project I'd like to build with
Maven 2
csi_build contains my Maven 2 binaries, AND a number of JDKs I use
for
builds. I store my JDKs in version control (Subversion), as some
deployments
require different versions of the JDK and because I want anyone to
be able
to pull down the latest code from the repository and immediately be
able to
execute a build, even if they don't have the JDK installed.
I simply go to the csi_common directory and execute the following
build.batfile
===
echo off
set
JAVA_HOME=C:\CSI\eclipse_workspaces\CSI\csi_build\src\tools\jdk
\jdk1.5.0_04
set
MAVEN_HOME=C:\CSI\eclipse_workspaces\CSI\csi_build\src\tools\maven
\maven-2.0
set PATH=%JAVA_HOME%\bin;%MAVEN_HOME%\bin;%PATH%
echo PATH=%PATH%
mvn package -e
===
Here's my simple pom.xml for csi_common
===

Please ensure you are using JDK 1.4 or above and
not a JRE (the com.sun.tools.javac.Main class is required).
In most cases you can change the location of your Java
installation by setting the JAVA_HOME environment variable.
