Intellij中的java Google ORTools:UnsatifiedLinkError

Question

我正在建立一个java框架，应该使用Google或其他工具。下面的代码编译成功，但在运行时引发异常：

Exception in thread "main" java.lang.UnsatisfiedLinkError: com.google.ortools.linearsolver.operations_research_linear_solverJNI.MPSolver_CLP_LINEAR_PROGRAMMING_get()I
    at com.google.ortools.linearsolver.operations_research_linear_solverJNI.MPSolver_CLP_LINEAR_PROGRAMMING_get(Native Method)
    at com.google.ortools.linearsolver.MPSolver$OptimizationProblemType.<clinit>(MPSolver.java:221)
    at Main.main(Main.java:15)

我正在Windows 10上使用Intellij 2018.3。我花了很多时间试着跑，但没有成功。根据我在互联网上的发现，这个例外可能是由于链接不良和/或缺少工具所依赖的外部库造成的。然而，我没有解决这个问题的背景，Intellij也没有强调任何东西。知道问题出在哪里吗

最后，我运行以下代码：

import com.google.ortools.linearsolver.MPObjective;
import com.google.ortools.linearsolver.MPSolver;
import com.google.ortools.linearsolver.MPVariable;

public final class Main {

  public static void main(String[] args) {

    // Create the linear solver with the GLOP backend.
    MPSolver solver =
        new MPSolver("SimpleLpProgram", MPSolver.OptimizationProblemType.GLOP_LINEAR_PROGRAMMING);

    // Create the variables x and y.
    MPVariable x = solver.makeNumVar(0.0, 1.0, "x");
    MPVariable y = solver.makeNumVar(0.0, 2.0, "y");

    System.out.println("Number of variables = " + solver.numVariables());

    // Create a linear constraint, 0 <= x + y <= 2.
    MPConstraint ct = solver.makeConstraint(0.0, 2.0, "ct");
    ct.setCoefficient(x, 1);
    ct.setCoefficient(y, 1);

    System.out.println("Number of constraints = " + solver.numConstraints());

    // Create the objective function, 3 * x + y.
    MPObjective objective = solver.objective();
    objective.setCoefficient(x, 3);
    objective.setCoefficient(y, 1);
    objective.setMaximization();

    solver.solve();

    System.out.println("Solution:");
    System.out.println("Objective value = " + objective.value());
    System.out.println("x = " + x.solutionValue());
    System.out.println("y = " + y.solutionValue());
  }
}
