宣告:僅限於將maven Repository下載的jar(使用maven打包的jar)安裝到本地的maven倉庫中,不保證全部成功,最初的時候新增依賴發現下載始終不成功,只能手動下載,但是手動下載完畢後,只能通過mvn install:install-file -Dfile=..這種方式安裝jar包到倉庫,實在是太過繁瑣,仔細觀察jar包後發現jar的座標資訊很容易從jar名稱已經jar內部的pom.properties檔案獲得,程式碼如下

測試結果:

1.eclipse中執行

2.打包成jar

3.可以指定目錄.預設的目錄為d:/jartoMVN/ ,直接拷貝路徑時記得加上 "/"
