我在 eclipse 中的服务器启动时收到此错误。使用PrepareForTest注释的单元测试运行良好。
我在pom.xml中添加了mockito-core，powermock-module-junit4，powermock-api-mockito作为依赖项。
此错误的原因可能是什么？谢谢！

所以这段代码找不到org.powermock.core.classloader.annotations.PrepareForTest。由于它似乎与 osgi 有关，我预计此代码的 OSGI 清单上会出现一些错误配置。
你应该朝这个方向调查，即为什么 eclipse OSGI 类加载器拒绝加载它。您可能需要添加更多OSGI规则（例如使用BN），因为您似乎有几个依赖项。
