1.在pom中添加dependency 后 没法把依赖下载到项目中【External Libraries】apache
视图如:segmentfault
解决方法:maven
(1)检查idea 的setting.xl文件配置路径是否配置正确ide
(2)从新导入maven依赖到项目中(reimport)idea
备注:能够在idea中把import Maven projects automatically 选项选中 ,那么在pom中添加dependency依赖 后 jar就会自动引入到项目中spa

2.每次down项目时检查idea 的file-->settings--->maven 的配置,确保下载下来的项目能够正确使用mavendebug
3.Idea不能新建package的解决3d

能够缘由target 目录正在被使用
场景:
此时我正停留在target目录中,因此致使target没法删除。
