嘗試了各種辦法：1、重裝IDE; 2、修改網上說的hosts檔案; 3、洗掉各種快取檔案 均無效，求各位大神指點，謝謝！

maven服務配置問題吧uj5u.com熱心網友回復：
確認一下在setting->build->build tools->maven里maven配置的config沒問題，特別是庫的路徑，驗證一下是不是通的。uj5u.com熱心網友回復：
好的，我一會試試。謝謝！
uj5u.com熱心網友回復：
很好，一直在找，謝謝！uj5u.com熱心網友回復：
看過了，沒問題，還是不行

maven的倉庫鏡像配下，用國內阿里的鏡像吧，默認的那個比烏龜還慢，有時還會出錯uj5u.com熱心網友回復：
能把具體專案的步驟描述下么？我也用的idea，按配置沒有問題直接ok的。uj5u.com熱心網友回復：
將maven版本降級一下，看行不行uj5u.com熱心網友回復：
樓主 問一下 這個問題你解決了沒有？ 如果解決了 麻煩告訴一下 這個問題是怎么解決的 謝謝uj5u.com熱心網友回復：

樓主問題解決了嗎？樓上的方法都試過了還是不行。uj5u.com熱心網友回復：
我的idea maven設定里設定的是maven安裝的路徑，設定好之后關掉設定在打開路徑就變了，變成C://.m2下的一個路徑，請問知道是怎么回事嗎？
uj5u.com熱心網友回復：
看看你的maven本地倉庫是不是在C盤，maven沒權限往C盤里寫入檔案，肯定下不動你要的依賴jar包
把你的maven本地倉庫移動到D盤或者EFGHJKL任意一個非系統盤去
