Install jar manually into maven and Nexus

Sometimes the maven building just needs one or more 3rd party jars, and the jars cannot be downloaded and installed automatically by Internet.

Then you can install these jars manually.

1st. Install a 3rd party jar package into maven repositor

mvn install:install-file -DgroupId=<jar's groupdId> -DartifactId=<artifactId> -Dpackaging=jar -Dversion=<version> -Dfile=<file location> -DgeneratePom=true

Just replace <> placeholder with your real case.

2nd. Install a 3rd party jar package into Nexus

For Nexus, you can only upload a 3rd party jar into the repository "3rd party", which is already installed as default as you setup Nexus server. Just click "3rd party" repository, and you will find a button called "Artifact upload" on the bar in the middle of the page.
