1.在pom中添加dependency 後 沒法把依賴下載到項目中【External Libraries】apache
視圖如:segmentfault
解決方法:maven
(1)檢查idea 的setting.xl文件配置路徑是否配置正確ide
(2)從新導入maven依賴到項目中(reimport)idea
備註:能夠在idea中把import Maven projects automatically 選項選中 ,那麼在pom中添加dependency依賴 後 jar就會自動引入到項目中spa

2.每次down項目時檢查idea 的file-->settings--->maven 的配置,確保下載下來的項目能夠正確使用mavendebug
3.Idea不能新建package的解決3d

能夠緣由target 目錄正在被使用

此時我正停留在target目錄中,因此致使target沒法刪除。
