Maven----将手动下载的jar包以命令行的方式安装到本地MavenRepository中

Posted 2020-10-19 LuckyDan

1.情景再现:准备实现SprintBoot的热部署功能,因没有对应jar时,在Eclipse中mvn install 会报错:

　　报错信息:

[INFO] --- spring-boot-maven-plugin:1.4.1.RELEASE:run (default-cli) @ spring-boot ---

2. 因Maven无法自动从网上仓库下载到相应的jar包,所以需要手动进行安装到本地MavenRepository中

　　命令格式如下:

mvn install:install-file -Dfile=jar包的位置(参数一) -DgroupId=groupId(参数二) -DartifactId=artifactId(参数三) -Dversion=version(参数四) -Dpackaging=jar

　　参数一:Jar包所在的位置

　　参数二:jar包的groupId

　　参数三:jar包的artifactId

　　参数四:jar包的版本号

3.实际操作:如下图

4. 特别注意事项:

　　4.1 注意"-"不能缺少 install后面的"-"是没有空格的
　　4.2 注意"-Dfile"中jar包的路径和jar包的名字.
　　4.3 注意看cmd命令提示,查看本地repository中是否成功的复制了jar包.
