# vim: tabstop=4 expandtab shiftwidth=4 softtabstop=4

echo "JAVA_HOME is not set"
exit
fi
if [ ! -f "$JAVA_HOME/bin/java" ]; then
echo "JAVA_HOME does not point to a valid java installation"
exit
fi

Another neat way to do this is to embed your groovy script inside a bash
script as per the method described in the following post:

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!

Hi Paul,
That worked great. Thank you!
However, it would be very convenient if I could specify the -cp using the
"java -jar" method like so:
java -jar groovy-3.0.9-indy.jar -cp . TestGroovy
The reason is that the example I gave you is a simplified example of what I
am actually doing. Although the method you gave me does work in my
situation too, it is situationally somewhat awkward. It would be very
convenient if the groovy jar accepted and used the -cp command. Is there
any way I can do that?
(Just FYI, I am working on https://github.com/blakemcbride/Kiss In
particular, see section 7 of
https://htmlpreview.github.io/?https://github.com/blakemcbride/Kiss/blob/master/manual/man/index.html
)
Thanks!

Hi Blake,
If you add the following line into your TestGroovy script:
println System.getProperty('java.class.path')
you will see that "." from the -cp commandline switch to java isn't
passed through to Groovy when using java -jar.
You can instead use (semicolon would be the path separator on Windows):
java -cp /path/to/groovy/jar:. groovy.ui.GroovyMain TestGroovy
or:
/path/to/groovy TestGroovy
Cheers, Paul.

Greetings,
I can run a simple Groovy class (TestGroovy.groovy) without explicitly
compiling it as follows:
java -jar groovy-3.0.9-indy.jar TestGroovy
I have a compiled Java class file named TestJava.class
I am not using any package declarations. everything is in the current
directory.
I changed TestGroovy.groovy to call my TestJava.class file, however, this
is what I am getting:
$ java -jar groovy-3.0.9-indy.jar TestGroovy
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
/home/blake/groovy/TestGroovy.groovy: 7: Apparent variable 'TestJava' was
found in a static scope but doesn't refer to a local variable, static field
or class. Possible causes:
You attempted to reference a variable in the binding or an instance
variable from a static context.
You misspelled a classname or statically imported field. Please check the
spelling.
You attempted to use a method 'TestJava' but left out brackets in a place
not allowed by the grammar.
@ line 7, column 3.
TestJava.javaMethod()

1 error
I also tried: java -cp . -jar groovy-3.0.9-indy.jar -cp . TestGroovy
With the same error.
Basically, I am trying to run a Groovy file and have it call a Java class
that I am supplying.
I am attaching the Java and Groovy files. Sure appreciate any help.
