没有指定前缀goal,配置错了，查看一下配置文件，加上前缀。

jar包冲突了，打开pom文件，点击下方的dependency hierarchy解决一下冲突的Jar包就行。

已经没有slf4j的冲突的jar包了，还是报错，原类还是执行不了，求解决，急！～

找不到application.xml，只有TEST-com.cy.CgbGoods01ApplicationTests.xml，求解决，急！～

我保留的是log4j-to-slf4j，还是报原来的错误，而且主类不能运行

这个项目是可以正常运行的，tomcat也是正常打开的，但是maven不能build，网页不能打开，求解，急！～

这是我排包的三个截图，好像还是不行，其中self-api文件反复出现，但是在resolved dependencies中只有一个

只剩下slf4j-api也会报错，用dependency-hierarchy排除，程序不能运行
