构建成功但没有可编译的源代码

Eclipse 控制台中的 Maven 测试输出：

上图显示了我的项目的目录，但是当我通过 Maven 运行该项目时，它在不运行测试的情况下给出了上述结果。期待一些准确的解决方案。

这就是我的 POM.XML 文件的样子：

Maven 是关于“约定优于配置” https://en.wikipedia.org/wiki/Convention_over_configuration成语。为了使maven-surefire-plugin将运行您的测试用例，它希望在下面找到它src/test/java，因此，您应该遵循maven的标准目录布局并将所有测试用例放在src/test/java.
