What about simply adding the jars to the classpath without any path, then when
you run the jar have your script cd into the directory where the jars are? The
jar with main will be in the same directory as its dependencies.
For example, my pom has
<!-- don't add classpath prefix; that way the jar can run -->
<!-- from any directory as long as the executing script -->
<!-- cds into the directory it's in. -->
<!-- <classpathPrefix> -->
<!-- ${classpathPrefix}/cars_download -->
<!-- </classpathPrefix> -->
<plugin>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<mainClass>
edu.berkeley.ist.cars.download.main.CarsDownloadMain
</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
Then my shell script (unix) looks like
JAVACMD=/usr/jdk/latest/bin/java
FLAVOR=download
RUNDIR=/users/facility/cars_runner/${FLAVOR}
JARFILE=cars_${FLAVOR}.jar
JARPATH=${RUNDIR}/${JARFILE}
# first cd to the directory where everything is.
# the classpath in the jar file doesn't specify the
# full path so we need to be in with the jars.
cd ${RUNDIR}
2>&1 ( ${JAVACMD} -jar ${JARPATH} ) >> ${RUNDIR}/logs/${FLAVOR}.log
Here's my assembly xml file that generates the zip file where all the jars and
shell script go in; this gets extracted on the server where the jar runs.
<?xml version="1.0" encoding="UTF-8"?>
<assembly>
<id>download</id>

<format>zip</format>
</formats>
<includeBaseDirectory>false</includeBaseDirectory>
<baseDirectory>/</baseDirectory>

have you had a look at the appassembler-mavn-plugin on mojo?
I use it and antrun and buildhelper to create a zip with batch files and
bash scripts and all the dependencies for projects

jar-with-dependencies is not a practical option for our project so we have
come up with a custom assembly that generates a zip/tar of:
- our projects jar
- a lib dir with all of our projects dependencies
- bat scripts to execute the jar
However I still need to add all of the jars in the lib to the classpath
when
invoking java in the bat scripts.
Is there any way to have maven add the appropriate dependencies entries for
the bat script based on the current runtime classpath?
