java maven编译错误：找不到符号 [英] java maven COMPILATION ERROR : cannot find symbol

问题描述

java maven编译错误：找不到符号
我正在使用eclipse从远程linux机器上构建Java maven项目。我使用Eclipse远程系统资源管理器（RSE）连接到项目。当我要全新安装项目时，似乎maven找不到我的某些类。

java maven COMPILATION ERROR : cannot find symbol I am using eclipse to build a java maven project from a remote linux machine. I get connected to project using Eclipse Remote System Explorer (RSE). When I want to clean install the project, it seems that maven cannot find some of my classes.

这是错误，我是项目POM文件。

This is the error and I the project POM file.

错误：
