mvn install:install-file -Dfile="D:\maven\repository\com\tc\itfarm-api\1.0.0-SNAPSHOT\itfarm-api-1.0.0-SNAPSHOT.jar" -DgroupId="com.tc" -DartifactId="itfarm" -Dversion="1.0.0-SNAPSHOT" -Dpackaging=jar
maven中maven dependencies中依赖出现了项目，把依赖的项目关掉，项目消失，但是还是无法打包 ，出现的错误如图。说明:依赖的项目为project-dao 打包的项目为project-service 都在project-parent中有依赖。project-dao是可以打包成功的。project-service中依赖dao的jar包也可以过来。

mvn install 可以解决问题
mvn -X clean install，-X表示强制从远程库更新dependency；再不行可能就是远程仓库没有架包了。
如果Nexus上没有架包，就需要用到上面的本地化安装架包命令
