PowerMock从@RunWith抛出异常（PowerMockRunner.class）注释

我试图让PowerMockito与我的应用程序一起工作。我已经将库添加到构建路径。我有以下的测试类：PowerMock从@RunWith抛出异常（PowerMockRunner.class）注释

package client.controller; 

import org.junit.Test; 
import org.junit.runner.RunWith; 
import org.powermock.core.classloader.annotations.PrepareForTest; 
import org.powermock.modules.junit4.PowerMockRunner; 

@RunWith(PowerMockRunner.class) 
@PrepareForTest(System.class) 
public class SampleTest 
{ 
    @Test 
    public void test() 
    { 

    } 
}

当我尝试运行测试，我得到以下异常：

按照PowerMock FAQ，我应该尝试使用旧包装。我做了，而且我仍然得到相同的例外。有任何想法吗？

瓶子被认为在类路径中包含'org.junit.internal.runners.TestClassRunner'？ – 2012-03-04 08:11:00

它似乎已在JUnit 4.5及更早版本中被删除/重命名。 – 2012-03-04 08:16:36

我正在使用JUnit 4.8.2。我如何检查课程路径？如果我尝试导入该包，Eclipse告诉我它无法解析。 – LandonSchropp 2012-03-04 08:47:42

看起来像我是PowerMock不正确地添加到构建。当我看着通过的问题在Eclipse中查看，我发现以下几点：

Archive for required library: 'lib/powermock-mockito-junit-1.4.11 4/powermock-release-junit-without-mock-framework-1.4.11.pom' in project 'Test' cannot be read or is not a valid ZIP file Test  Build path Build Path Problem 
Archive for required library: 'lib/powermock-mockito-junit-1.4.11 4/powermock-release-without-test-and-mock-framework-1.4.11.pom' in project 'Test' cannot be read or is not a valid ZIP file Test  Build path Build Path Problem

从固定的问题的构建路径删除这两个文件。

对我来说，混乱开始使用JUnit版本，

显然4.12> 4.4在JUnit版本。

所以对于版本> 4.4，则需要使用powermock-module-junit4

，而不是powermock-module-junit4-legacy。

作为一个方面说明，后来我发现我不得不使用powermock-api-mockito2

，而不是powermock-api-mockito

这就是进步......
