Maven commands aren't complete in the DIY installation instructions?

[olance]

On MacOS X (10.6.4), the mvn commands gave me build errors, telling me I was missing group, artifact, version or packaging information.

I managed to get it installed with:
mvn install:install-file -Dfile=xmlson-1.5.2.jar -DpomFile=xmlson-1.5.2.pom -Dversion=1.5.2 -DgroupId=com.wesabe -Dpackaging=jar -DartifactId=xmlson

and:
mvn install:install-file -Dfile=shore-0.2-SNAPSHOT.jar -DpomFile=shore-0.2-SNAPSHOT.pom -Dversion=0.2-SNAPSHOT -DgroupId=com.codahale -DartifactId=shore -Dpackaging=jar

Hope those are the correct parameters, and that it can maybe help others ^^
