【问题描述】：

我在单元测试用例中使用了 Mockito 和 Power Mockito。当我运行配置文件代码覆盖率时，我能够生成 jacoco 报告，但是

我在测试阶段尝试生成 Jacoco 报告时出错

错误 [错误] 无法在项目 testproject-api 上执行目标 org.jacoco:jacoco-maven-plugin:0.8.2:report (default-report)：JaCoCo 报告生成时出错。：创建报告时出错：出错时分析 d:\workspace\api\target\classes\pkg\ResponseBuilder.class。无法处理检测类 pkg\ResponseBuilder.class。请提供原始的非仪器类。 -> [帮助 1]

【参考方案1】：

问题现已解决。我需要为 default-restore-instrumented-classes 目标添加测试阶段。请找到更新后的代码
