I am using JDK 1.8 which is installed in the system. 我正在使用系统中安装的JDK 1.8。 Is it a maven plugin issue? 它是Maven插件问题吗? I think the xml configurations are almost fine. 我认为xml配置差不多可以了。
I am using eclipse oxygen.For the first time I am running a spring project using oxygen. 我正在使用日食氧气,这是我第一次使用氧气运行春季项目。 Can anyone help me to solve this? 谁能帮我解决这个问题?
