I'm trying to test a class that has a private constructor. I know that I can use PowerMockito to mock the constructor, but I don't want to use PowerMockito because it has some limitations. I want to use Mockito. I found a solution in Mockito's GitHub. I copied the code from this link to my project. But I get an error. I don't know why. Here is the code:Error:Exception in thread "main" java.lang.NoSuchMethodError: org.mockito.internal.util.JavaEightUtil.invokeNullaryFactoryMethod(Ljava/lang/Class;)Ljava/lang/Object;at org.mockito.internal.creation.instance.InstantiatorProvider$1.newInstance(InstantiatorProvider.java:54)at org.mockito.internal.creation.instance.InstantiatorProvider$1.newInstance(InstantiatorProvider.java:51)at org.mockito.internal.creation.instance.InstantiatorProvider.getInstantiator(InstantiatorProvider.java:49)at org.mockito.internal.creation.instance.InstantiatorProvider.getInstantiator(InstantiatorProvider.java:38)at org.mockito.internal.creation.instance.InstantiatorProvider.getInstantiator(InstantiatorProvider.java:33)at org.mockito.internal.creation.instance.InstantiatorProvider.getInstantiator(InstantiatorProvider.java:28)at org.mockito.internal.creation.instance.InstantiatorProvider.getInstantiator(InstantiatorProvider.java:23)at org.mockito.internal.creation.instance.InstantiatorProvider.getInstantiator(InstantiatorProvider.java:18)at org.mockito.internal.creation.instance.InstantiatorProvider.getInstantiator(InstantiatorProvider.java:13)at org.mockito.internal.creation.instance.InstantiatorProvider.getInstantiator(InstantiatorProvider.java:8)at org.mockito.internal.creation.instance.InstantiatorProvider.getInstantiator(InstantiatorProvider.java:3)at org.mockito.internal.creation.instance.InstantiatorProvider.getInstantiator(InstantiatorProvider.java:8)at org.mockito.internal.creation.instance.In
