How to invoke groovy with 'java' from command line

Question

I have to ship some groovy code to some users that have only java installed (no grooy, no $groovy_home, etc). I'm trying to invoke groovy from the commandline but I'm having no luck. Here's my bat file:

java -classpath .;lib;bin;bin-groovy introspector.AclCollector

And here's my exception:

Exception in thread "main" java.lang.NoClassDefFoundError: groovy/lang/GroovyObject

Could not find the main class: introspector.AclCollector.  Program will exit.

Does anyone have a clue? I have 'groovy-all-1.6-beta-1.jar' in \lib dir.

Answer 1

I think you need to explicitly list the groovy jar in the classpath

Answer 2

You have here another example of Groovy app called from Java (in this case, from ant, but the general idea is the same).

java -cp [...];%GROOVY_HOME%/embeddable/groovy-all-1.5.4.jar;[..]

As mentioned by frankowyer, you have the exact groovy jar explicitly listed on the classpath arguments of the java.

Since your clients do not have special environment variable, just replace the %GROOVY_HOME%/... with the complete path to:

• groovy.jar or
• goovy-all-VERSION.jar (to minimize any conflict with other libraries)
