Mvn problem with import

I tried to enhance the valloxmv binding. No problems with building it in eclipse.

But in maven I get the following error compiling an (unchanged) file.

[ERROR] import;
[ERROR] ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
[ERROR] The import cannot be resolved

Maven command was (as always)

mvn clean install

in the directory of the binding.

Do I have to adapt anything towards the ESH merge? Or is the problem just sitting in front of the screen?
