Hi,

Did you use the Maven pom.xml to get all the necessary dependencies for the project.
So with m2eclipse or mvn eclipse:eclipse from the command line?
The pom.xml includes the groovy dependency so you should get it in that way.

Best regards,

I do have m2eclipse installed and did the update dependencies but i don't see anywhere in the pom.xml an entry for groovy.

Thanks for your help!

I looked at the posted link and I don't have the asm jar older version in the listed folder yet I get an error

org.activiti.engine.ActivitiException: Can't find scripting engine for 'groovy'
at org.activiti.engine.impl.scripting.ScriptingEngines.evaluate(ScriptingEngines.java:71)
at org.activiti.engine.impl.bpmn.behavior.ScriptTaskActivityBehavior.execute(ScriptTaskActivityBehavior.java:43)
at org.activiti.engine.impl.pvm.runtime.AtomicOperationActivityExecute.execute(AtomicOperationActivityExecute.java:44)

Do I need to manually add the dependency to pom.xml for groovy? I'm following the Book "Activiti In Action" to run the unit test listed in Chapter 2 Page 17, there was no mention of updating pom so I assumed the dependency will be pulled by activiti but that does not seem to be the case, I used m2eclipse to get the activiti project started and my pom currently is as follows

fixed it by manually editing pom and adding the following dependency

   <dependency>
      <groupId>org.codehaus.groovy</groupId>
      <artifactId>groovy</artifactId>
      <version>1.7.5</version>
   </dependency>

Following the book to start the bmpn-examples from scratch had this missing element, this may help others who are following the book and getting started like me

I did not see the groovy reference in the book so adding it manually allowed me to run the Example for the BookOrder.
