Optaplanner: java.lang.NoSuchMethodError: com.google.common.collect.MapMaker.makeComputingMap

Question

@Test
    public void test_whenDroolsSolver(){
        SolverFactory<CourseSchedule> solverFactory =
                SolverFactory.createFromXmlResource("courseScheduleSolverConfigDrools.xml");
        Solver<CourseSchedule> solver = solverFactory.buildSolver();
        CourseSchedule solvedCourseSchedule = solver.solve(unsolvedCourseSchedule);

        Assertions.assertNotNull(solvedCourseSchedule.getScore());
        Assertions.assertEquals(0, solvedCourseSchedule.getScore().getHardScore());
    }

我正在运行上述Optaplanner应用程序的单元测试，但遇到了以下错误。

java.lang.NoSuchMethodError: com.google.common.collect.MapMaker.makeComputingMap(Lcom/google/common/base/Function;)Ljava/util/concurrent/ConcurrentMap;

我运行的是Maven guava 23.0库，它没有makeComputingMap方法。切换到旧版guava 13.0可以解决这个问题，但又出现了另一个缺失的方法。

java.lang.NoSuchMethodError: com.google.common.collect.Sets$SetView.iterator()Lcom/google/common/collect/UnmodifiableIterator;

buildSolver类org.optaplanner.core.impl.solver.DefaultSolverFactory.buildSolver似乎运行在一些出现在旧版本和新版本的guava类上，我有办法解决这个问题吗？

Answer 1

升级OptaPlanner（也升级Drools）到最新版本，使用guava 25.0。
