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
===============================================
<project xmlns="http://maven.apache.org/POM/4.0.0"; xmlns:xsi="

===============================================
The output complains "Unable to locate the Javac Compiler in:

Here's the output:

Why in the world is the Maven code looking for anything in C:
\jre1.5.0_04
???
if I issue "set JAVA_HOME" from the command line, I get:
===============================================
C:\CSI\eclipse_workspaces\CSI\csi_common>set JAVA_HOME
JAVA_HOME=C:\CSI\eclipse_workspaces\CSI\csi_build\src\tools\jdk
\jdk1.5.0_04
===============================================
and here's my path:
===============================================
C:\CSI\eclipse_workspaces\CSI\csi_common>set PATH
Path=C:\CSI\eclipse_workspaces\CSI\csi_build\src\tools\jdk
\jdk1.5.0_04\bin;
C:\CSI\eclipse_workspaces\CSI\csi_build\src\tools\maven\maven-2.0\bin;
C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem
===============================================
Also, if I issue "javac" from the command line, I get:
===============================================
C:\CSI\eclipse_workspaces\CSI\csi_common>javac
Usage: javac <options> <source files>
where possible options include:
-g Generate all debugging info
-g:none Generate no debugging info
-g:{lines,vars,source} Generate only some debugging info
-nowarn Generate no warnings
-verbose Output messages about what the
compiler is
doing
-deprecation Output source locations where
deprecated APIs
are used
-classpath <path> Specify where to find user class files
-cp <path> Specify where to find user class files
-sourcepath <path> Specify where to find input source files
-bootclasspath <path> Override location of bootstrap class

-extdirs <dirs> Override location of installed extensions
-endorseddirs <dirs> Override location of endorsed

-d <directory> Specify where to place generated class

-encoding <encoding> Specify character encoding used by

-source <release> Provide source compatibility with

-target <release> Generate class files for specific VM
version
-version Version information
-help Print a synopsis of standard options
-X Print a synopsis of nonstandard options
-J<flag> Pass <flag> directly to the runtime
system
===============================================
So, I KNOW javac is in the path.
Can anyone shed some light on what I may be doing wrong?
Sincerely,
Matthew Wheaton
