The goal you specified requires a project to execute but there is no POM in this directory

My order is

mvn install:install-file -Dfile=D:\cao\gofastdfs-2.0.jar  -DgroupId=com.aaa-DartifactId=gofastdfs -Dversion=2.0 

I searched Baidu all over to find the correct writing ： Parameters need to be enclosed in quotation marks

mvn install:install-file "-Dfile=D:\cao\gofastdfs-2.0.jar"  "-DgroupId=com.aaa" "-DartifactId=gofastdfs" "-Dversion=2.0" 

After the implementation, this error was not reported , But he made another mistake ：

Failed to execute goal org.apache.maven.plugins:maven-install-plugin:2.4:install-file 
(default-cli) on project standalone-pom: The artifact information is incomplete or not valid:

Later, I found that it was necessary to add “-Dpackaging=jar”

The complete order is ：

mvn install:install-file "-Dfile=D:\cao\gofastdfs-2.0.jar"  "-DgroupId=com.aaa" "-DartifactId=gofastdfs" "-Dversion=2.0" "-Dpackaging=jar

Perfect solution ！
