java.lang.IncompatibleClassChangeError using Scriptom 1.6 on Groovy 1.7.10

Question

I try to use scriptom 1.6 on Windows 7 to connect to excel application. However I keep getting the error:

Caught: java.lang.IncompatibleClassChangeError: Class org.codehaus.groovy.scriptom.ActiveXObject does not implement the requested interface groovy.lang.GroovyObject
    at GoBeby.main(GoBeby.groovy:14)

Here is my code:

import org.codehaus.groovy.scriptom.ActiveXObject;

class GoExcel {


    public static void main(String[] args) {

        ActiveXObject excel = new ActiveXObject("Excel.Application")
        excel.Visible = true;


    }
}

and maven file:

I just run out of ideas. I have check to use jacob 64bit and 32 bit dll, change groovy framework to 1.5. Has anybody any idea how to make it work?

Answer 1

One possibility is that you are using 1.6.0 version of scriptom and 1.7.0 version of groovy. Looking at scriptom pom, it depends on 1.6.0 version of groovy.
