[rules-users] EDT dependency -- transitive dependencies broken from 4.07 to 5?

[Ingomar Otter]

Hi Andrew,
I've seen this in 4.0.7 as well.
There is a dependency from drools-compiler to either Eclipse JDT or  
Janino for compilation, depending on what compiler you choose. JDT is  
default by now.

Both compilers are supplied with 5M2 bin-dist, see lib/janino.jar and  
lib/core-3.4.2.....jar for JDT. Make sure to include the JDT jar in  
your build and you should be fine.

What's strange is that you see this using maven, as this is an  
explicit dependency in the drools-compiler pom. Ehm, maybe I can't  
really help here. :-(


Cheers,
   Ingomar
