Hi everyone!

The error: "Can't find scripting engine for 'groovy'" it's clearly.
Can't find groovy language, so: check if your groovy libs are in last stable version, tomcat7 can conflict with old groovy versions, or if your groovy dependency declaration in pom.xml is right. I have solved my problem with a correct dependency declaration in pom.xml:

wrong:

dependency>
   <groupId>org.codehaus.groovy</groupId>
   <artifactId>groovy</artifactId>
   <version>2.0.1</version>
  </dependency>

rigth:


dependency>
   <groupId>org.codehaus.groovy</groupId>
   <artifactId>groovy-all</artifactId>
   <version>2.0.1</version>
  </dependency>
Now, it works fine, before this refactoring, scriptTypes "osama" or "groovy" show same error

My ambient: Activiti 5.10, Tomcat 7.0.22, Groovy 2.0.1

If only I had read this last couple of posts before banging my head against the wall trying to get activiti to notice the groovy scripting engine in version 2.0.x…..  I changed my dependencies back to;
<blockcode>
        <dependency>
            <groupId>org.codehaus.groovy</groupId>
            <artifactId>groovy</artifactId>
            <version>1.7.5</version>
        </dependency>
</blockcode>
Which worked but its nice to know that to get 2.0.x working the artifactId needs to be <artifactId>groovy-all</artifactId>.

I also verified that it works with the latest version of groovy;

<blockcode>
        <dependency>
            <groupId>org.codehaus.groovy</groupId>
            <artifactId>groovy-all</artifactId>
            <version>2.1.3</version>
        </dependency>
</blockcode>

Thanks for the post

Yes indeed. The old groovy jar used to contain the scripting engine, but that was changed with the 2.0 version. Now you need to use the -all jar.

I added the note to the docs: https://github.com/Activiti/Activiti/commit/bb96ca6ae22437b0851196abefce88569f13d682
