我试图在我的测试用例中使用Powermockito来测试遗留void delete()内部的public final ClassToTestmethod但是当我在mockStatic上调用ClassToTest时抛出这个异常
这是一个例外：

我的ivy.xml for dependencies看起来像这样：
<dependency org="junit" name="junit" rev="4.11"/>
<dependency org="org.mockito" name="mockito-all" rev="1.9.5"/>
<dependency org="org.powermock" name="powermock-module-junit4" rev="1.7.3"/>
<dependency org="org.powermock" name="powermock-api-mockito" rev="1.7.3"/>
<dependency org="org.powermock" name="powermock-core" rev="1.7.3"/>
在测试方法内部我使用这些注释：
@RunWith( PowerMockRunner.class )
@PrepareForTest( ClassToTest.class )
@PowerMockIgnore( {"javax.management.*"})
我做了一个调试，发现它在尝试加载这个类的时候发现它完全失败了：
org.powermock.api.mockito.repackaged.ClassImposterizer
依赖项中是否缺少某些内容？或者别的我做错了？
org/mockito/internal/creation/instance/InstantationException类已经在Mockito的2.x版本中引入，并且在1.9.5版本中不可用。
同样基于兼容性表，您应该将Powermock 1.5.6版本作为最新支持1.9.5 Mockito的目标。 supported versions
Mockito 1.9.5是一个非常古老的版本。您可以尝试使用最新的stable-1.10.19进行更改。
尝试在intellij中使用Idea依赖分析器插件并解决冲突，这看起来像是依赖冲突。 PS更新mockito到最新的2. *版本，我这样做没有冲突或问题，新版本非常好
