Greetings,
For my case, I think I have found a perfect solution. I created the
following bash script named run:
-------------------------------
#!/bin/bash
# This script allows the running of a Groovy file in the context of the
# entire system.
JAR_PATH=`dirname $0`/../lib
CLASSES_PATH=`dirname $0`/../build/web/WEB-INF/classes
THE_CLASSPATH=.
for i in `ls $JAR_PATH/*.jar`
do
THE_CLASSPATH=${THE_CLASSPATH}:${i}
done
THE_CLASSPATH=${THE_CLASSPATH}:${CLASSES_PATH}
java -cp ${THE_CLASSPATH} groovy.ui.GroovyMain "$@"
------------------------------------
I am then able to run a groovy file in the context of the rest of my system
(this system has 9500 classes and 89 jar files). I can now simply do:
run MyGroovyFile
Thanks!
Blake
