Create a Confluence "Hello World" Macro fails

I tried to create a Macro for Confluence and i do this with the Atlassian Tutorial (

The first steps were fine and i can see the macro in the add-on list.


When I want to add the Macro to a testpage, i am not able to do this. Even opening the Macro-Browser fails, also if i want to add a macro from the list that is already given. In the terminal i can see something like:

[INFO] [talledLocalContainer] caused by: java.lang.NoClassDefFoundError: Could not initialize class com.benryan.conversion.macro.ConverterMacro
[INFO] [talledLocalContainer] at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)
