based on our discussion about removing any datatype dependency from
the swt module, I created a small module just to run the swt module. I
added the data deps and let maven do its thing.
Funny thing is that now I have the same
java.lang.AbstractMethodError
at
org.geotools.filter.function.DefaultFunctionFactory.getFunctionName(DefaultFunctionFactory.java:106)
at
org.geotools.filter.function.DefaultFunctionFactory.loadFunctions(DefaultFunctionFactory.java:134)
...
also from within the module created a la Quickstart. No eclipse
involved. So I can only guess i am doing something strange.
Any further idea?
