Maven adds a local jar package to the MAVEN repository

Maven adds a local jar package to the MAVEN repository
MVN install:install-file-dgroupid=io.netty-dartifactid=netty-all-dversion=5.0.0.alpha1-dpackaging=jar-dfile=
G:/java/jar Bag/netty-all-5.0.0.alpha1.jar

The jar package I downloaded was placed in the D:\MVN directory (D:\mvn\spring-context-support-3.1.0.RELEASE.jar)
So the command I typed in cmd would be:

MVN Install:install-file-dfile=d:\mvn\spring-context-support-3.1.0.release.jar-dgroupid=org.springframework- Dartifactid=spring-context-support-dversion=3.1.0.release-dpackaging=jar
