mvn clojure:swank throws java.lang.NumberFormatException: Invalid number: 2009-09-14

For some reason the 'swank' target of the clojure-maven-plugin isn't working for me on Windows. At home, on Ubuntu, it works fine. At work, with the same code base, it doesn't work. It throws the following exception:

Exception in thread "main" clojure.lang.LispReader$ReaderException: java.lang.NumberFormatException: Invalid number: 2009-09-14

I decided to work around this by extending my 'clj' starter script. I added a --pom switch which tells the script to build the classpath using the pom file in the current directory. It makes use of the build-classpath target of the maven-dependency-plugin. So now at work I can start up a Swank server simply by typing:

clj --pom "c:\dev\nwalex.com\clojure-scripts\start-swank.clj"

I have this aliased to 'swank' in my .aliases file in Cygwin.

Anyway, here's the full script:

#!/bin/bash

function init_classpath {
    # set up the classpath dynamically. Note this includes the jline jar
    CLASSPATH=""
    for jarfile in `ls -l ~/.clojure-classpath/ | pcol 11`; do
        JAR=`cygpath --windows $jarfile`
        CLASSPATH="$CLASSPATH;$JAR"
    done
}

function init_classpath_from_pom {
    echo "Initializing classpath from pom.xml..."

    # create the classpath file
    mvn dependency:build-classpath -Dmdep.outputFile=classpath 2>&1 > /dev/null

    # store it and remove the file
    CLASSPATH=`more classpath`
    rm classpath

    # also add everything under the clojure source directories
    CLASSPATH="$CLASSPATH;./src/main/clojure;./src/test/clojure"
}
 
if [ $# -eq 0 ] ; then
    init_classpath
    stty -icanon min 1 -echo
    java -Djline.terminal=jline.UnixTerminal -cp $CLASSPATH jline.ConsoleRunner clojure.main
else
    TMPFILE=""
    while [ $# -gt 0 ] ; do
        case "$1" in
        --pom)
            init_classpath_from_pom
            ;;
        -cp|--classpath)
            CLASSPATH="$CLASSPATH;$2"
            shift
            ;;
        -e)
            TMPFILE="/tmp/$(basename $0).$$.tmp"
            /bin/echo $2 > $TMPFILE
            ARGS=$TMPFILE
            break
            ;;
        *)
            ARGS="$ARGS $1"
            ;;
        esac
        shift
    done

    if [ "$CLASSPATH" == "" ] ; then
        init_classpath
    fi

    if [ "$ARGS" != "" ]; then 
        ARGS=`cygpath --windows $ARGS`
    fi
 
    java -cp "$CLASSPATH" clojure.main $ARGS
    if [ "$TMPFILE" != "" ] ; then
        rm $TMPFILE
    fi
fi

start-swank.clj is simply:

(require 'swank.swank)
(swank.swank/start-server "nul" :encoding "utf-8" :port 4005)

Update 1: Updated script to include the src/main/clojure and src/test/clojure directories on the classpath.
