Проблемы с Maven: плагин maven-clean не найден в репозитории

Вздох.

Используя maven 2.2.1, внезапно он не может разрешить maven-clean-plugin. И действительно, насколько безумно, что инструменту сборки требуется плагин для «очистки»?

Я попытался синхронизировать мой каталог .m2 с другой машины, которая работает нормально, и я получил те же результаты.

Мой помпон выглядит так: creaMatriu (N, 0, [T]): - креафила (N, 0, T),!. ...

I made a little code for creating a matrix of coordinates (like a chessboard), it's the following:

createMatrix(N,M,R) :- creaMatriu(N,M,A), reversed(R,A).
creaMatriu(N,0,[T]) :- creafila(N,0,T),!.
creaMatriu(N,M,[T|C]) :- creafila(N,M,T), M1 is M-1, creaMatriu(N,M1,C).
creafila(0,M,[[M,0]]):-!.
creafila(N,M,[[M,N]|C]) :-N1 is N-1,creafila(N1,M,C).
reversed(A, B) :- reversed(B, [], A).
reversed([A|B], C, D) :- reverse(N,A),reversed(B, [N|C], D).
reversed([], A, A).

The first time I executed it went well, but when i incremented the dimensions of the matrix, the "dots" at the end of the matrix begin to appear incrementing one coordinate as the dimension rises, as like this:

?- createMatrix(1,1,R).
R = [[[0, 0], [0, 1]], [[1, 0], [1, 1]]] .

?- createMatrix(2,1,R).
R = [[[0, 0], [0, 1], [0, 2]], [[1, 0], [1, 1], [1, 2]]] .

?- createMatrix(2,2,R).
R = [[[0, 0], [0, 1], [0, 2]], [[1, 0], [1, 1], [1, 2]], [[2, 0], [2, 1], [2, 2]]] .

?- createMatrix(3,2,R).
R = [[[0, 0], [0, 1], [0, 2], [0, 3]], [[1, 0], [1, 1], [1, 2], [1, 3]], [[2, 0], [2, 1], [2, 2], [2, 3]]] .

?- createMatrix(3,3,R).
R = [[[0, 0], [0, 1], [0, 2], [0, 3]], [[1, 0], [1, 1], [1, 2], [1, 3]], [[2, 0], [2, 1], [2, 2], [2, 3]], [[3, 0], [3, 1], [3, 2], [3|...]]] .

?- createMatrix(4,3,R).
R = [[[0, 0], [0, 1], [0, 2], [0, 3], [0, 4]], [[1, 0], [1, 1], [1, 2], [1, 3], [1, 4]], [[2, 0], [2, 1], [2, 2], [2, 3], [2|...]], [[3, 0], [3, 1], [3, 2], [3|...], [...|...]]] .

?- createMatrix(4,4,R).
R = [[[0, 0], [0, 1], [0, 2], [0, 3], [0, 4]], [[1, 0], [1, 1], [1, 2], [1, 3], [1, 4]], [[2, 0], [2, 1], [2, 2], [2, 3], [2|...]], [[3, 0], [3, 1], [3, 2], [3|...], [...|...]], [[4, 0], [4, 1], [4|...], [...|...]|...]] .

Anyone have any clue why this happens?

Thank you!
