1.情景再現:準備實現SprintBoot的熱部署功能,因沒有對應jar時,在Eclipse中mvn install 會報錯:

　　報錯信息:

2. 因Maven無法自動從網上倉庫下載到相應的jar包,所以需要手動進行安裝到本地MavenRepository中

　　命令格式如下:

mvn install:install-file -Dfile=jar包的位置(參數一) -DgroupId=groupId(參數二) -DartifactId=artifactId(參數三) -Dversion=version(參數四) -Dpackaging=jar

　　參數一:Jar包所在的位置

　　參數二:jar包的groupId

　　參數三:jar包的artifactId

　　參數四:jar包的版本號

3.實際操作:如下圖

4. 特別註意事項:

　　4.1 註意"-"不能缺少 install後面的"-"是沒有空格的
　　4.2 註意"-Dfile"中jar包的路徑和jar包的名字.
　　4.3 註意看cmd命令提示,查看本地repository中是否成功的復制了jar包.

Maven----將手動下載的jar包以命令行的方式安裝到本地MavenRepository中
