java – PowerMock从@RunWith(PowerMockRunner.class)注释中抛出异常

我正在努力让powermockito使用我的应用程序.我已将库添加到构建路径中.我有以下测试类：

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()
    {

    }
}

当我尝试运行测试时,我得到以下异常：

根据PowerMock FAQ,我应该尝试使用旧版程序包.我做了,我仍然得到同样的例外.有任何想法吗？

最佳答案

看起来我正在错误地将PowerMock添加到构建中.当我查看Eclipse中的问题视图时,我发现了以下内容：

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

从构建路径中删除这两个文件解决了问题.
