本文记录了在使用Maven进行单元测试时遇到的问题及解决过程。主要问题是测试类未被找到，导致测试无法正常执行。通过对构建流程的分析，发现测试资源未正确编译并复制到指定目录。

我的报错信息如下：

maven 调用surefire执行单测的过程：

先是clean -> jacoco agent -> maven-resources-plugin -> maven-compiler-plugin -> maven-resources-plugin:testresource ->

maven-compiler-plugin:testCompile ->maven-surefire ->test run jacoco-maven-plugin report -> maven-jar-plugin -> install

找不到test类，就是没有编译，在testresource compile no file compile to copy 到执行的单元测试目录下。
