External static methods not being recognized in the project

Question

I am importing a library of utils into my main project, the library currently contains a single static method, I can import both manually and by Maven, but I am not able to access the static method of the library. I am using Spring boot, Maven and JDK 1.8 in the project the library was created with JDK 1.8.

Class inside the . jar:

import java.util.List;

public class CalculoGeografico {
    public CalculoGeografico() {
    }

public static boolean CalcularPontoDentroPoligono(List<Double> latidudes, List<Double> longitudes, Double pontoLatitude, Double pontoLongitude) {
    boolean result = false;
    int j = latidudes.size() - 1;

    for(int i = 0; i < latidudes.size(); j = i++) {
        if (((Double)latidudes.get(i) < pontoLatitude && (Double)latidudes.get(j) > pontoLatitude || (Double)latidudes.get(j) < pontoLatitude && (Double)latidudes.get(i) > pontoLatitude) && (Double)longitudes.get(i) + (pontoLatitude - (Double)latidudes.get(i)) / ((Double)latidudes.get(j) - (Double)latidudes.get(i)) * ((Double)longitudes.get(j) - (Double)longitudes.get(i)) < pontoLongitude) {
            result = !result;
        }
    }

    return result;
}
}
