[news.eclipse.technology.equinox] trying to build do p2 generation with

["John Kelly" <john.kelly@xxxxxxxxxx>]

Hi,

I'm trying to add p2 generation to our build.xml with is already building 
our update site (site.xml etc..)
Our build machine DOES NOT HAVE ECLIPSE installed, so i'm trying to cut down 
the generation process to a bare minimum,  if possible.
(please excuse my ignorance if what i'm trying to do is "dumb")

Firstly, I need to know if it's possible to build in this way (see ant task 
below below).

I've read quite a bit of literature around the web and I've got as far as I 
can..
I'm now stuck on a "Java returned: 13" problem

All suggestions gratefully received - thanks in advance
John

Details are...

I've created an ant target as below...

   <java classpathref="eclipsep2.classpath" fork="true" failonerror="true"
  classname="org.eclipse.equinox.launcher.Main" >
  <arg line=" -application 
org.eclipse.equinox.p2.metadata.generator.EclipseGenerator \
              -debug \
           -consoleLog \
           -updateSite ${lib.dir} \
              -site file:${lib.dir}/site.xml \
              -metadataRepository file:${lib.dir} \
              -metadataRepositoryName '${PRODUCTTITLE} Update Site' \
              -artifactRepository file:${lib.dir} \
              -artifactRepositoryName '${PRODUCTTITLE} Artifacts' \
              -compress \
              -reusePack200Files" />
    </java>
 </target>

my classpath includes the following jars

  <include name="org.eclipse.equinox.launcher_1.0.1.R33x_v20080118.jar" />
  <include 
name="org.eclipse.equinox.p2.metadata.generator_1.0.0.v20080604.jar" />
  <include 
name="org.eclipse.equinox.p2.artifact.repository_1.0.1.v200808061616.jar" />
  <include 
name="org.eclipse.equinox.p2.exemplarysetup_1.0.0.v20080427-2136.jar" />
  <include name="org.eclipse.equinox.p2.ui.sdk_1.0.0.v20080605-1731.jar" />
  <include 
name="org.eclipse.equinox.simpleconfigurator.manipulator_1.0.1.R34x_v20080911-1720.jar" 
/>

the console output looks like this...

p2:
     [java] Install location:
     [java] file:/c:/xxx/buildoutput/lib/
     [java] Configuration file:
     [java] file:/c:/xxx/buildoutput/lib/configuration/config.ini not found 
or not read

     [java] Shared configuration location:
     [java] file:/c:/xxx/buildoutput/lib/configuration/
     BUILD FAILED
C:\xxx\src\build.xml:150: Java returned: 13

if i look in generated directory C:\xxx\buildoutput\lib\configuration i find 
a log file with contents thus..
