This post is a solution on a previous issue:
OptaPlanner - Problems with the solver configuration for two planning entity classes
This was the error:
Exception in thread "main" java.lang.IllegalArgumentException: Unmarshalling of solverConfigResource (org/optaplanner/examples/nurserostering/solver/nurseRosteringSolverConfig.xml) fails.

回答1:
The problem was caused because in the <swapMoveSelector> i inserted a <valueSelector> tag but as it says in the documentation
The SwapMove selects 2 different planning entities and swaps the planning values of all their planning variables.
The solution was simple: just remove the <valueSelector> from the <swapMoveSelector>
