Usually I just manually copy in third party jars to our Maven repository when they come by, but recently I decided to give Maven's own tools a try. In this example, I'm deploying a MyLEAD jar Scott Jensen has sent my way:
mvn deploy:deploy-file -DgroupId=mylead -DartifactId=mylead-crosscut-attr \
-Dversion=1.0 -Dpackaging=jar -Dfile=./mylead_crosscut_attr-1.0.jar \
-Durl=scpexe://rainier.extreme.indiana.edu/l/extreme/java/repository
And here, I deploy it again, but this time as a Maven1 type artifact, to support Maven1 clients:
mvn deploy:deploy-file -DgroupId=mylead -DartifactId=mylead-crosscut-attr \
-Dversion=1.0 -Dpackaging=jar -Dfile=./mylead_crosscut_attr-1.0.jar \
-Durl=scpexe://rainier.extreme.indiana.edu/l/extreme/java/repository \
-DrepositoryLayout=legacy
