I'm trying to deploy and execute a very simple workflow that runs a groovy script.I implemented the code in Eclipse and I can successfully execute it, but when I try to export it to a .jar file, using Maven, I'm getting an exception saying: Can't find scripting engine for 'groovy'.I've seen a couple

Hi,

is groovy-all jar in the classpath of the application where you runs your project?

Yes, it is in the classpath and when I run the application from the eclipse everything is fine.
The problem is when I run the application from the console, using the .jar file generated with Maven.

I really don't know may be the problem…

Does the jar include the groovy-all jar (ie a fat jar)? Do you add the groovy-all jar to the classpath when executing the jar?

Yes, the jar includes the groovy-all jar.

The pom is presented below. I'm compiling the code with the following command: mvn clean compile assembly:single package
And then running the jar by just doing java -jar NAME_OF_THE_JAR. Am I missing something? Do I need to define any environment variable before running the jar? Thanks!

Yes you are: if you run java -jar NAME_OF_JAR, groovy_all will not be on the classpath.
You need to run with java -cp path/to/your/libs -jar yourjar.jar (or create a fat jar that includes it)
