I've read thoroughly the manual and examples but still can't find the reason
for this behavior. First, some pointers to state my case.
- Environment: Windows XP SP3, Ant 1.8.1, jdk1.6.0_02
- My project builds and run fine from the cmdline, provided that the CLASSPATH
env. variable is set. I can even get a working jar executable from it, so the
manifest file (created manually) is also ok. So I tried to repeat the
development & deployment process using Ant.
First, I deleted the CLASSPATH env variable to avoid problems. Rebooted my
system.
This is my package structure (relative paths):
[root.dir]\ant builfiles\ //contains the xml buildfiles for my
projects
[root.dir]\projects\
[root.dir]\projects\modules\
[root.dir]\projects\modules\src\
[root.dir]\projects\modules\src\packages\ // source code for general purpose
auxiliary
// classes, w/ subpackages
[root.dir]\projects\modules\src\apps\ // source code for the actual
project classes
[root.dir]\projects\modules\src\resources\ // icons and other files required
by projects
[root.dir]\projects\WEB-INF\
[root.dir]\projects\WEB-INF\build\ // destdir for the <javac> task
[root.dir]\projects\WEB-INF\dist\ // destdir for the <jar> task
Both the build.xml and build.properties files are located in the "ant
buildfiles" folder.
The following is the build.properties file:
src.dir=../projects/modules/src
build.dir=../projects/WEB-INF/build
dist.dir=../projects/WEB-INF/dist
project.name=gdv
main-class=apps.gdv.v1_0_0.GDVLauncher
jar-classpath=.\\gdv.jar // the double backslash is an escape
sequence
// and it works fine (more details later)
and this is build.xml file:
<?xml version="1.0"?>
<project name="gdv" default="run">
<property file="build.properties"/>
<target name="clean">
<delete dir="${build.dir}"/>
<delete dir="${dist.dir}"/>
</target>
<target name="init" depends="clean">
<echo>Creating the build directories</echo>
<mkdir dir="${build.dir}"/>
<mkdir dir="${dist.dir}"/>
<!-- this section is an alternate method to include resource files:
<copy todir="${build.dir}/resources">
<fileset dir="${src.dir}/resources"/>
</copy>
Basically is a workaround to get a jar file containing the resource files and a
valid manifest despite the whenmanifestonly="skip" property set in the <jar>
task. I inspected the resulting manifest file and found it exactly as expected.
Manifest and resources are present, the packages with the bytecode obviously
not (compilation fails).

Finally, here's the verbose output of the ant command:

I apologize for this long, boring report, I hope you find the time to read it
entirely.
Any help will be greatly appreciated, thanks in advance for your patience.
